Electrostatic discharge can permanently damage your equipment. Always ground yourself by touching the system cabinet before touching any internal component. We strongly recommend using an antistatic wrist strap attached to cabinet ground. To open a desktop case: 1. Turn off the monitor and system unit power. Unplug the AC power cables and disconnect any other cables attached to the back of the system unit. 2. Remove the plastic bezel from the back of the case by pulling it away from the case. 3. Unscrew the five mounting screws at the back of the case that hold the case cover to the system unit chassis. 4. Slide the case cover back and up. Be careful not to snag any cables or connectors inside the case. 5. Set the case cover aside while you work on your system. 6. When through, reattach the case cover, screws, bezel, and cables in the reverse order. The figures show the plastic bezel, screw locations, and cover motion for a desktop case. 16 Chapter 1 - The Big Picture Mounting Screws Cover Chassis Plastic Bezel 17 Chapter 1 - The Big Picture How to Open a Vertical Case Caution: Whenever you open the case or work inside the computer there is danger of electrostatic discharge. Electrostatic discharge can permanently damage your equipment. Always ground yourself by touching the system cabinet before touching any internal component. We strongly recommend using an antistatic wrist strap attached to cabinet ground. Opening a vertical case is almost identical to opening a desktop case. To open a vertical case: 1. Turn off the monitor and system unit power. Unplug the AC power cables and disconnect any other cables attached to the back of the system unit. 2. Remove the plastic bezel from the rear of the case by pulling it away from the case. 3. Unscrew the six mounting screws at the back of the case that hold the case cover to the system unit chassis. 4. Slide the case cover back and up. Be careful not to snag any cables or connectors inside the case. 5. Set the case cover aside while you work on your system. 6. When through, reattach the case cover, screws, bezel, and cables in the reverse order. The figures show the plastic bezel, screw locations, and cover motion for a vertical case. 18 Chapter 1 - The Big Picture Mounting Screws Cover Plastic Bezel Chassis 19 Chapter 1 - The Big Picture Inside a Desktop System Unit The figure below shows some of the most common components inside the system unit case. Expansion Boards Expansion Slots Power Supply Mainboard Hard Disk Drive CPU Floppy Drives, CD-ROM Drives, and Tape Backup Units The mainboard is the large circuit board at the bottom of the system unit case. It is the heart of your system. All of the other components inside the case work for the mainboard. The power supply delivers electricity to the mainboard. The disk drives, keyboard connectors, and other parts of the system unit bring information to and from the mainboard. 20 Chapter 1 - The Big Picture Inside a Vertical System Unit Floppy Drives, CD-ROM Drives, and Tape Backup Units Power Supply Hard Disk Drive Mainboard Expansion Slots Expansion Boards CPU Vertical systems have all the same components as desktop systems. The figure shows the mainboard and common components inside a vertical system unit case. 21 Chapter 2 - The Mainboard 2. The Mainboard The mainboard is the large circuit board located at the bottom of the system unit case. It is the heart of your computer system. This board contains the central processing unit (CPU), secondary cache subsystem, expansion slots, ports and connectors for other computer components, and the system main memory or RAM. Mainboard Features Your mainboard includes: Intel Pentium (TM) Processor running at 60Mhz, 66Mhz, or 90 Mhz Small Computer System Interface (SCSI) host adapter socket Optional 256K or 512K secondary system cache Integrated Windows compatible Business Audio that supports ADPCM compression Integrated floppy drive controller Two local bus IDE hard drive interface ports supporting up to 4 IDE devices Enhanced Parallel Port Two full-function, RS232, 16550-compatible serial ports High-speed system memory; expandable from 2MB to 192MB Flash BIOS; relocatable to 32-bit high-speed RAM for faster performance Five 16-bit ISA expansion slots Three 32-bit PCI, local bus, high-speed expansion slots Clock/calendar with on-board battery backup 22 Chapter 2- The Mainboard PCI Local Bus 32-Bit High Speed Expansion Slots The three PCI local bus, high speed expansion slots move information at up to 133 MB/s. This provides an extremely high performance, 32-bit interface to support high speed, local bus video adapter cards and other peripherals such as LAN adapters and hard disk drives. Secondary Cache Subsystem The secondary cache subsystem enhances the performance of the CPU. The integrated cache controller and a cache memory SIMMs provide the secondary cache subsystem for the system. Either one 256K Cache SIMM or one 512K cache SIMM provides the cache memory. Keyboard Selectable Speed You can increase system performance by activating Turbo mode with the keyboard. <+> activates turbo mode (default). <-> disables turbo mode. Note: Some Pantera systems have a Turbo LED and Turbo button on the front of the case. The Turbo button and Turbo LED are not used on Pantera systems. Only the keyboard command enables or disables turbo mode. 23 Chapter 2 - The Mainboard On-Board Peripherals Your mainboard has all of the standard peripheral interfaces and many extras built in. This eliminates the need for many peripheral expansion cards and greatly enhances system reliability. The integrated peripheral interfaces include: Optional SCSI port (supports both SCSI-1 and -2 type devices) Two serial ports Parallel port Floppy drive controller Two IDE hard drive controller ports each capable of controlling two hard drives Business audio with speaker output jack, alternate internal speaker output, and microphone input jack Serial Port Your mainboard has two RS232C asynchronous serial ports, which are generally referred to as COM1 (9-pin) and COM2 (25-pin) ports. The serial ports are used to attach mice, serial printers, modems, or other serial peripheral devices. Both serial ports are 16550 UART compatible for higher data transfer rates. You can install up to two additional serial ports (COM3 and COM4) simultaneously in your system. However, MS-DOS does not manage more than two COM ports simultaneously very well. Therefore, while you can install and use four COM ports, do not attempt to use more than two at the same time or you may run into problems. Specifically, you should not try to use COM1 and COM3 at the same time, or COM2 and COM4 at the same time. 24 Chapter 2 - The Mainboard Parallel Port The 25-pin Centronics parallel port is often called the printer port because it is generally used only for printers. However, the parallel interface has achieved a high level of standardization. The parallel port is also EPP or Enhanced Parallel Port compatible. This means you can use the port to connect other peripheral devices designed to use a Centronics parallel interface. SCSI Port The optional on-board SCSI host adapter allows you to connect and control up to seven peripheral devices such as SCSIcompatible disk drives, tape backup units, communications devices, and CD-ROM drives. The SCSI port is a parallel, multitasking interface which supports both SCSI-1 and SCSI-2 devices. The SCSI port is configured from the system SETUP program. For SCSI system setup parameters, refer to the SCSI Control Menu in Using SETUP. Business Audio Ports The on-board business audio adapter chip allows you to use a built-in external speaker jack and microphone input jack for fullfeatured audio support of many popular software packages. The external speaker jack and microphone input jack are mounted on a bracket at the back of the system unit. 25 Chapter 2 - The Mainboard Mainboard Connectors Connectors are used to attach devices to the mainboard. Attached devices can be internal like hard disk indicator lights, or external like serial and parallel ports. The most commonly used connectors are shown in the Mainboard Diagram. A detailed description is provided in the table below.

Input Audio board cable connector 27 Chapter 2 - The Mainboard Mainboard Jumpers Jumpers are small groups of pins that can be connected or disconnected with jumper caps. To connect a jumper, place the jumper cap over the pins you wish to connect and gently press down. The Pantera mainboard uses only two jumpers. The mainboard stores most configurations in battery backed CMOS memory. The Pantera mainboard uses the SETUP program to reconfigure options stored in battery backed memory. The Pantera mainboard also uses the FLASH programming utility to update the system BIOS. Other mainboards use jumpers to configure upgrade options and parameters directly on the board. The Pantera mainboard uses the SETUP program and the FLASH programming utility instead, making upgrades and changes fast and easy. FLASH1 The FLASH1 jumper allows or disallows re-programming of the FLASH BIOS with the FLASH utility program. The default or normal position is to allow programming with the FLASH program. CLR1 The CLR1 jumper holds or resets the CMOS battery backed SETUP memory. You should not clear the CMOS SETUP memory unless it becomes corrupted and cannot be reprogrammed with the SETUP program. To clear the CMOS memory, turn off system power , then momentarily place the jumper in the CLEAR position, then return the jumper to the NORMAL position. Your system will not operate with the jumper in the CLEAR position, so be sure to return the CLR1 jumper to the NORMAL position. 28 Chapter 2 - The Mainboard Mainboard Jumpers Diagram 29 30 Chapter 3 - Using SETUP 3. Using SETUP The Extended BIOS Software System consists of several programs which work along with the system BIOS. Together, they provide additional system customization. You can access the Extended BIOS Main Menu by pressing F2 during system boot. Use the arrow keys to highlight and select the utility and then press Enter. The Main Menu allows you to choose between: Main Menu options Advanced System Setup Security Exit Each of the main screens allows you to choose several submenus. You navigate through the Extended BIOS software using the cursor keys and several function keys. You can also load the original factory default settings from ROM, load the current settings from battery backed CMOS, or save new changes to CMOS. Press F1 at any time for help. To make changes to SETUP values, use the arrow keys to select the desired item. The selected item will be highlighted. The + and - keys allow you to scroll through the available options. Only items surrounded by square brackets may be changed. Press F9 to load the SETUP defaults from ROM. Press F10 to load your previous settings from CMOS. Exit through the Exit menu. Press Enter to see a sub-menu, Esc to return to the previous menu. 31 Chapter 3 - Using SETUP Main Menu Your system setup has been configured at the factory for maximum performance and reflects all options you may have ordered. Generally, you need to run SETUP only if you change your system's hardware configuration, such as installing a different hard drive, or if the on-board battery fails. The SETUP Main Menu allows you to change: Time and date Video System System memory configuration Floppy drive types The Main Menu also offers you the following sub-menus: Fixed Disk 0-3 Type SCSI BIOS Enable Memory Control Memory Shadow Boot Sequence 32 Chapter 3 - Using SETUP Main Menu Options System Time Sets the real-time clock, using a 24-hour format. During the power-up sequence, the real time is read and saved in memory for use by the operating system. After boot up, the operating system updates the system time. System Date Sets the real-time date for month, day, and year. During the power-up sequence, this information is read and saved in memory for use by the operating system to determine the current date. After completing the power-up sequence, the operating system updates the current date. Diskette Drive A: Specifies the size and capacity of the floppy-disk drive installed as drive A. Options are: 360K, 720K, 1.2M, 1.44M, and 2.88M Diskette Drive B: Specifies the size and capacity of the floppy-disk drive installed as drive B. Daylight Savings Allows the system clock to adjust automatically for daylight savings time. The default is enabled. Video System This option can be set to one of the following: Monochrome 80 column Color Graphics (CGA 80 x 25) Enhanced Graphics Adapter or VGA (EGA/VGA)(default) 33 Chapter 3 - Using SETUP Main Menu Options System Memory Sets the system memory size. This is set to 640KB at the ZEOS factory. MS-DOS can manage conventional memory of 640KB without additional software. You should not need to change this value. Extended Memory Defines the size of extended memory in 64K increments. Extended memory is the total amount of memory not used as System Memory and for Shadow RAM (384K is allocated for Shadow RAM). For example, a system with 2MB (2048KB) installed (BIOS shadowed) will indicate 1024KB of extended memory [i.e.: 2048KB - (640KB + 384KB) = 1024KB]. Fixed Disk Menu The Fixed Disk Menu lists each of the installed IDE hard/fixed disks. Your first, or primary hard drive is Fixed Disk 0. If you have additional hard drives installed or want to install more drives, they will be configured as Fixed Disk 1, 2, or 3. 34 Chapter 3 - Using SETUP Fixed Disk 0 Type Sets the hard drive 0 configuration. This option was set to Auto at the ZEOS factory prior to shipment. In most cases, this option is all you need. When Auto is selected, the system determines what kind of hard drive is installed and displays the drive parameters. Note: Only change this option setting if you change your hard drive. Multi-Sector Transfer Determines the number of sectors per block for multiple sector transfers. Options are Disabled, 2, 4, 8, and 16. The default is 16. Older hard drives (and even some newer drives) will not work properly if the number of sectors is set too high. LBA Mode Control Enables or disables Logical Block Addressing, allowing you to use large IDE hard drives. This must be enabled for IDE hard drives greater than 528 MB. Physical Drive Determines the physical address of the drive. Options are : Default, Primary Master, Primary Slave, Secondary Master, and Secondary Slave. The default is Default. Fixed Disk 1 - 3 Control If your system has more hard drives installed, again set these options to Auto. This sets the drive type for the additional hard drives. Never needlessly change the default setting. 35 Chapter 3 - Using SETUP SCSI BIOS Enable Menu The SCSI default configuration settings are appropriate for most system installations. Configuration changes are only necessary when using nonstandard (older) SCSI devices or nonstandard peripheral expansion cards. SCSI BIOS Enabled Enables or disables the integrated SCSI BIOS. Controller Address The on-board SCSI controller always uses IRQ11, non-DMA. If other attached devices are using IRQ11, change their settings to a different IRQ. The SCSI I/O port default address is 340h (primary). The alternate address is 140h, but is not supported by the system BIOS at this time. Synchronous This parameter selects whether synchronous data transfer with SCSI targets should be initiated. When disabled, the system will still respond to negotiations initiated by SCSI targets. This option is generally used when an older SCSI device is installed which doesn't recognize synchronous negotiation. The default is enabled. Note: Some SCSI devices like CD-ROM drives may require this parameter to be disabled. 36 Chapter 3 - Using SETUP Enhanced Enable this option if you are using a hard drive larger than 1GByte. This option enables enhanced mode disk geometry translation. If the BIOS detects a drive capacity greater than 1GByte, it uses 255 head/ 63 sector translation. Otherwise it uses 64 head/ 32 sector translation. This option also allows for higher synchronous transfer rates of 6.67 MBytes/sec. or 10 MBytes/sec. Parity Enables parity checking by the on-board SCSI controller. Parity is supported by most SCSI devices. If this option is disabled, the SCSI controller still generates parity, but no interrupt will be generated on parity errors. Disconnect Enables a SCSI device to disconnect from the on-board controller if it will take a long time to complete a requested operation, and later reconnect when ready to finish. Use this feature to improve bus use in multitasking environments. Single task environments like DOS usually work smoother when this option is disabled. However, some tape backup units will operate better when this option is enabled, even under DOS. The default is disabled. 37 Chapter 3 - Using SETUP Memory Control The memory control sub-menu allows you to make detailed changes to your system memory configuration. External Cache This option permits you to enable or disable the external cache memory. Some applications are not compatible with caching. This option allows you to disable memory caching, if necessary. Cache Video BIOS area This option controls caching of the video BIOS. Enabling this option could improve video performance. The default is enabled. Note: Not implemented on all systems. Idt 7MP6157 256K Module: or Motorola MCM67A618 512K Selects Dual Write Enable Mode for the external system cache module. Set this to TRUE if you are using a 256K Idt module with a 7MP6157 part number or if you are using a 512K Motorola module with an MCM67A618 part number. DRAM speed Always set the DRAM speed to the slowest speed of all your installed memory SIMMs. Your mainboard supports 60ns or 70ns memory chips. Note: Not implemented on all systems. 38 Chapter 3 - Using SETUP Memory Shadow Shadowing is the technique of mirroring or copying portions of the computer's slower, read-only memory into much faster system memory. Shadowing key portions of memory generally improves system performance. System Shadow System shadow is always enabled. Video Shadow Enables or disables copying of the video BIOS into RAM. Shadowing the video BIOS may improve your video response time. The default is enabled. Shadow Memory Regions Allows you to choose which specific memory regions will be shadowed. The default is for all specific regions disabled. 39 Chapter 3 - Using SETUP Boot Sequence Menu The boot sequence sub-menu allows you to speed up boot time by disabling certain standard computer boot procedures. Keyboard Auto-repeat Rate Defines the rate the keyboard repeats when a key is pressed and held. The number displayed represents the number of repetitions per second the keyboard will generate. The default is 30 times per second. Keyboard Auto-repeat Delay Defines time delay between the time a key is depressed and the time the key begins to repeat. The default is 1/2 second. Key Click When selected, provides an audible feedback whenever a key is pressed. Numlock This option defines how the Num Lock key should work on power up. The Num Lock key is used to determine whether the cursor keys or the numeric keys are active on the keypad. Normally, the BIOS sets the Num Lock (numeric keys active) if the system detects a compatible keyboard on power up. Auto On Off Sets the Num Lock (numeric keys active) if the system detects a compatible keyboard on power up (default) Selects the numeric keys regardless of the keyboard Selects the cursor movement keys regardless of the keyboard Summary screen During normal boot, the system BIOS displays a summary screen of your computer configuration at boot. Disabling the system summary screen at boot skips this display. 40 Chapter 3 - Using SETUP Floppy Check When enabled the system checks that each floppy drive configured in CMOS memory is operational. Disabling floppy check skips this step, speeding up boot time. Floppy Swap For systems that boot using DOS, allows you to swap the drive designation for floppy drives A: and B:. Enabled swaps the drives. Disabled uses the drives as they are installed. Note: Not implemented on all systems. Boot Sequence During boot the computer looks for an operating system stored on the floppy boot drive or logical drive C on an installed hard drive. Disk drive boot sequence determines which drive is checked first. The default is [A: then C:], meaning the system will check floppy drive A first, then if no operating system is present, it will look on drive C. If you normally boot from the hard disk C, setting this option to [C: then A:] or [C: only] will speed your boot time. SETUP prompt When enabled, the system displays the message "Press F2 to enter SETUP" on boot. When disabled this step is skipped on boot. POST errors When enabled, the system pauses whenever it finds an error during bootup and displays the message "Press F1 to continue or F2 to enter SETUP". When disabled the system ignores POST errors during boot. The default is enabled. 41 Chapter 3 - Using SETUP Advanced Menu Warning! Setting these items incorrectly could disable your system. Never needlessly change from the defaults. The Advanced Menu offers the following options: Large Disk DOS Compatibility Enables or Disables Logical Block Addressing, enabling you to use very large IDE hard drives. Note: Not implemented on all systems. Integrated Peripherals This menu allows you to set the addresses, interrupts and DMA channels for your serial, parallel, and audio ports. Com Port A: When either Com Port 1 or Com Port 2 is set to Auto, the system will automatically set the interrupts for both ports. Otherwise this option allows you to set the interrupt and I/O address of the COM1 serial port. Com Port B: When either Com Port 1 or Com Port 2 is set to Auto, the system will automatically set the interrupts for both ports. Otherwise this option allows you to set the interrupt and I/O address of the COM2 serial port. 42 Chapter 3 - Using SETUP Parallel Port Sets the parallel port designation. The default setting of Auto allows the system to automatically assign the first available parallel port designation to the on-board parallel port (usually LPT1). Otherwise allows you to specify the parallel port address. Mode Allows you to specify the parallel port as Uni-directional (default) or Bi-directional. Audio Port Sets the interrupt and DMA access for the audio port. The default is IRQ9, DMA 6. You may also choose IRQ9 with DMA 5, or IRQ11 with DMA 5 or 6. The port can also be disabled. Note: The on-board SCSI controller will automatically use IRQ11. If you use both the SCSI controller and the audio port, be sure the audio port is set to IRQ9. PCI Devices The PCI Devices sub-menu allows you to set specifications for the PCI bus and for PCI devices connected to the bus. If you are inserting a PCI controller card into one of your PCI slots, this screen allows you to set the interrupt for the slot. The top row of the table at the bottom of the screen explains which of the four steering interrupts (0 through 3) needs an interrupt entry. For example, a card inserted in PCI slot 6 needs an interrupt entered on Interrupt Steering Register 0. Note: For more help setting PCI bus master interrupts, call ZEOS Technical Support at 1-800-228-5390. 43 Chapter 3 - Using SETUP Security The system security options allow you to password-protect system access. Whenever a password is entered, you must reenter the proper password to access the system. To protect yourself from forgetting your passwords, we strongly recommend writing them down and storing for safekeeping. Warning! If you forget the password, your system will not operate. You will have to completely clear the CMOS memory and re-enter your entire system configuration. Write down your password and store it in a safe place. The following security items are available: Set Supervisor Password Set User Password Password on Boot Diskette Access Fixed disk boot sector System Backup Reminder Virus Check Reminder Set Supervisor Password Allows you to enter a system supervisor password. Set User Password Allows you to enter a system user password. You can only enter a user password if a supervisor password is also entered. 44 Chapter 3 - Using SETUP Password on Boot When enabled, the system asks you for a password on boot. The system will only boot if the correct supervisor or user password is entered. The default is disabled. Diskette Access Specifies which level of password is required to access the floppy drives. This option prevents unauthorized copying of information. The default is Supervisor. Fixed disk boot sector When enabled, write protects the boot sector on your hard drive to protect against viruses. System Backup Reminder When enabled, displays boot reminder message to back up your system every day, week, or month. The default is disabled. Virus Check Reminder When enabled, displays boot reminder message to scan for viruses every day, week, or month. The default is disabled. Exit Menu Offers Exit and Save options for the SETUP program. 45 Chapter 4 - How to Add and Expansion Board 4. How to Add an Expansion Board The expansion slots on your mainboard are designed to accept a wide variety of cards or boards. Components such as scanners, tape backup units, video capture devices, and many others use expansion cards (also called expansion boards) to communicate with the CPU on the mainboard. Often adding these components is as easy as opening the case, slipping the new card into an empty expansion slot, and connecting the component to the card. To add an expansion board: 1. Turn off the monitor and system unit power and unplug the AC power cords from the wall outlet. 2. Open the system unit case (see How to Open a Desktop Case, earlier). 3. Find an empty expansion slot or, if you are replacing an expansion card already in your system (such as when upgrading your video card), locate the old card. 4. Unscrew the mounting screw and remove the blank bracket by sliding it up. If you are removing an old expansion card, carefully lift it straight up. 5. Set any jumpers or switches on the new card. See the expansion board's documentation for the correct jumper settings. 46 Chapter 4 - How to Add an Expansion Board Mounting screw Expansion slot 6. Slide the new board into place. Press firmly so the edge connector on the card slides all the way into the expansion slot. 7. Screw in the mounting screw. 8. Connect any internal cables to the expansion card. 9. Close the system unit case, and turn on the power. Many expansion boards require you to run diagnostic or installation software before the new board will work properly. Look in your expansion board installation instructions for more detailed information. 47 Chapter 5 - How Disk Drives Work 5. How Disk Drives Work There are three main types of disks for storing files - floppy, hard, and compact disks. Floppy disks are small, relatively slow, portable disks. Most people use floppy disks to transfer files or install new programs onto their hard drives. Floppy disks fit into the floppy disk drives mounted in your system unit. Although there are some combination drives, most floppy disk drives are designed to hold only one size of disk. Hard, or fixed disks, are permanently mounted inside your system unit case. They are very fast, hold a lot of files, and are not removable without dissassembling your system. Compact disks fit into CD-ROM drives. Compact disks can store very large amounts of information. Floppy, hard, and CD-ROM disk drives all fit into the drive bays in your system unit. This chapter shows how some of the most common drives connect to the mainboard. Most drives have two connections - a power connection and a data connection. For detailed installation and configuration information, always check the disk drive's documentation. 48 Chapter 5 - How Disk Drives Work How a Floppy Drive Works Floppy drives have two primary connectors, a ribbon cable called the data cable, and a power connection to the power supply. The ribbon cable connects the back of the floppy drive with the floppy controller port J5 on the mainboard. Data ribbon cables often have two connectors. If you have more than one floppy drive on your system, they often share the same ribbon cable. The data cable also has a red stripe. Whenever connecting or disconnecting the ribbon cable, be sure to attach the cable connectors so the red stripe is pointing toward pin 1 of the connector. Pin 1 is often labelled with a small triangle or filled in corner.

IDE devices have most of the electronics or "smarts" built into the drive, rather than installed on a separate controller card or on the motherboard. IDE hard drives have two main connections ­ a ribbon cable called the data cable and a power connection to the power supply. The ribbon cable attaches to the back of the drive and connects to the IDE controller port J6 or J7 on the mainboard. Whenever connecting or disconnecting the ribbon cable, be sure to attach the data cable so the red stripe points toward pin 1 on the connector. Most drives also have configuration jumpers at the back of the drive for setting drive identification and resistors. See your hard drive user's guide for complete information.
