These shocks 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 opposite show the plastic bezel, screw locations, and how to remove a desktop PC's cover. 14 Chapter 1 - The Big Picture Mounting Screws Cover Chassis Plastic Bezel 15 Chapter 1 - The Big Picture How to Open a Tower Case Caution: Whenever you open the case or work inside the computer there is danger of static electric shock. These shocks 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 tower case is almost identical to opening a desktop case. To open a tower 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, taking care not to snag any cables or connectors inside. 5. Set the case cover aside while you work on your system. 6. Afterwards, reattach the case cover, screws, bezel, and cables in the reverse order. The figures opposite show the plastic bezel, screw locations, and cover motion for a tower case. 16 Chapter 1 - The Big Picture Mounting Screws Cover Plastic Bezel Chassis 17 Chapter 1 - The Big Picture Inside a Desktop Computer Expansion Slots Power Supply Hard Disk Drive Mainboard CPU Front of Computer Floppy Drives, CD-ROM Drives, and TapeBackup Units The mainboard is the large circuit board at the bottom of the chassis. 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. The figure above shows some of the most common components inside the computer. 18 Chapter 1 - The Big Picture Inside a Tower Computer Power Supply Floppy Drives, CD-ROM Drives, and TapeBackup Units Front of Computer Expansion Slots Hard Disk Drive Mainboard CPU Tower systems have the same components as desktop systems. The figure above shows the mainboard and typical components inside a Tower case. 19 Chapter 2 - The Mainboard 2. The Mainboard The mainboard is the largest circuit board in the computer. It contains the CPU (Central Processing Unit), the Level 2 cache, expansion slots, ports and connectors for other components, and the system's main memory, or RAM (Random Access Memory). Mainboard Features Standard Features: · Intel Pentium (P54C) running at 75, 90, 100, 120, or 133MHz · Optional 256K or 512K Level 2 system cache, write-back, directmapped · Integrated onboard floppy drive controller · Two onboard IDE hard drive interface ports supporting up to 4 IDE devices (both are PCI local bus) · Bidirectional Parallel Port (configurable through software) · Two RS232, 16550 high-speed serial ports · RAM Configurations: 2, 4, 6, 8, 10,12, 16, 32, 64, 128, 192, 384MB, etc. (Banks must hold identical pairs) · 384Mb maximum RAM capacity · Flash BIOS, relocatable to system RAM to boost performance · Five 16-bit ISA expansion slots · Three 32-bit PCI local bus expansion slots · Clock/calendar with onboard battery backup · Energy saving, low power "sleep" mode Factory Installed Options: · AMD SCSI host adapter socket on PCI bus · AMD network controller on PCI bus 20 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 132 MB/s. This offers a high performance, 32-bit interface to support local bus peripherals such as video cards, LAN adapters and hard disk drives. Secondary Cache Subsystem The secondary (Level 2) cache subsystem enhances the performance of the CPU. The onboard cache controller allows cache memory to provide an ultra high-speed, 12-15-nanosecond buffer between the CPU and conventional (50, 60, or 70ns) RAM. Your system can accommodate three cache configurations: 0K, 256K, or 512K of Level 2 cache. The single cache slot (labelled CACHE) is located next to the CPU. Continuous Full-Speed Processing Pantera systems now run continuously at maximum speed, eliminating Turbo Mode. Because of this, the Turbo button and Turbo LED are not used on Pantera systems. 21 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. Integrated onboard peripherals include: · Two serial ports (16550 UART) · Parallel port (bidirectional, assigned through SETUP) · Floppy drive controller (handles floppy drives up to 2.88Mb) · Two PCI local bus IDE hard drive controller ports, each capable of controlling two hard drives Factory installed options: · SCSI port (supports both SCSI-1 and -2 type devices) · Ethernet port 22 Chapter 2 - The Mainboard Serial Ports Your mainboard has two RS-232C asynchronous serial ports, which are usually referred to as COM1 or COMA (9-pin) and COM2 or COMB (25pin) 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, because MS-DOS does not manage more than two COM ports simultaneously very well, you shouldn't attempt to use more than two COM ports at the same time. Specifically, don't try to use COM1 and COM3 at the same time, or COM2 and COM4 at the same time. 23 Chapter 2 - The Mainboard Parallel Port The 25-pin Centronics parallel port is often called the printer port because it is usually used for printers. However, devices that use this speedy parallel interface are becoming more common. Your Pantera's parallel port is also Bidirectional, allowing data to flow to and from an external device at the same time. 24 Chapter 2 - The Mainboard PCI SCSI/ Ethernet Port The optional onboard SCSI (host adapter allows you to connect and control up to seven peripheral devices such as SCSI-compatible 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. The SCSI host adapter socket can also accept an Ethernet LAN controller chip allowing you to make direct Ethernet LAN connections for high speed local area network communications. Note: The onboard SCSI and LAN options are factory installed options only. The onboard SCSI and LAN option can only be upgraded at the time of purchase. 25 Chapter 2 - The Mainboard Mainboard Diagram 16 bit ISA Expansion Slots BIOS Chip 32-bit PCI Expansion Slots 16 bit ISA Expansion Slots Main 9-pin Serial Power Port COMA Supply J2 Connectors PS1 Keyboard Connector J1 25-pin Serial Port COMB J3 Parallel Port J4 BIOS slot 6 slot 1 slot 2 slot 7 slot 8 DB9 Standard Power Connector P9 P8 J2 Floppy Header J5 Secondary IDE Hard Drive Header J8 Primary IDE Hard Drive Header J7 SIMM Sockets for System RAM 10Base2 Adapter Header J9 Parallel Floppy slot 4 slot 3 slot 5 FLSH CLR DB25 J4 J3 3v Power Connector PS2 Secondary Power Supply J5 P10 Legacy ISA Header J6 J6 PWR IDE 1 & 2 System Battery IDE 3 & 4 1 J8 J7 CPU Clock Jumper CLK1 CLK1 Bank 0a Bank 0b Bank 1a Bank 1b Bank 2a BNC Assembly : 010-0050-xx Future Optional Secondary Socket & CPU CACHE1 J9 Secondary CPU (future) U21 CACHE1 Jumper SCSI Device Header J11 J11 SCSI Cache Socket RJ-45 Bank 2b AMD LAN/SCSI Chip J10 FD1 LAN Filter Chip Primary CPU U26 Level 2 SIMM Socket (System Cache) Voltage Regulator VREG Socket 5 MUTE_LED LAN/SCSI Chip Socket (optional) U27 PDF cmax3.cdr 950405 10BaseT Adapter Header J10 10BaseT Filter Chip Socket FD1 MUTE Primary CPU RESET 20 or 40MHz Osc. for AMD chip J15 J14 SPEAKER J13 KBDLOCK IR1 Mute LED, Mute Input (not used) & Reset Input (J15) HDD LED & PC Speaker Header J14 Power-On LED & Keyboard Lock J13 LAN/SCSI Chip Clock Oscillator Y3 26 Chapter 2 - The Mainboard Mainboard Connectors Connectors and headers are used to attach peripheral devices to the mainboard.

To connect a jumper, carefully place the jumper cap over the pins you wish to connect, then gently press down. The mainboard uses four jumpers, allowing great system flexibility. However, most system settings are stored in battery-backed CMOS (Complimentary Metal-Oxide Semiconductor) memory. You can use the BIOS SETUP program to change settings stored in the CMOS. Other mainboards use jumpers to configure upgrade options and parameters on the mainboard. Pantera mainboards use the SETUP program and the FLASH programming utility instead, making BIOS changes and upgrades without removing the BIOS chip. FLSH The FLSH jumper allows or disallows reprogramming of the FLASH BIOS with the FLASH utility program. The factory default (NORMAL) setting allows you to reprogram the BIOS with the FLASH utility. CLR The CLR jumper maintains your BIOS settings or allows you to restore them to factory defaults. Settings are stored in a CMOS (Complimentary Metal-Oxide Semiconductor) chip. Do not clear these settings unless they become corrupted and cannot be reprogrammed with the SETUP program, which also can reset the factory default BIOS settings. To clear the CMOS memory: 1. Turn off system power and remove the case (pp.14-16). 2. Remove the CLR jumper (p.28). This disconnects the CMOS battery. 3. Turn on system. System will report a dead battery. Turn off system, replace the CLR jumper. Settings are now cleared. 4. Turn on system, enter SETUP (press the F2 key during bootup). 5. Reconfigure BIOS settings, including passwords and LBA Mode Control (if your hard drive holds more than 528MB). 6. Save and Exit SETUP. (continued next page) 30 Chapter 2 - The Mainboard CLK1 The CLK1 jumper sets the speed of the system clock. It will be set correctly to work with your system, so don't change this jumper unless you change CPUs. Pins Jumpered 1-2 , 5-6 5-6 1-2 3-4, 5-6 1-2, 3-4 CPU Clock Speed (MHz) 75 90 100 120 133 Bus Clock Speed (MHz) 50 60 66 60 66 See the diagram, Mainboard Jumpers, for the location of all jumpers. CACHE1 A fast CPU operates more efficiently when it has a buffer of ultrafast RAM between itself and system RAM. The CACHE1 jumper configures how Level 2 cache is used by your system. 256K to 512K of cache can be added by inserting a standard cache SIMM. The cache controller is integrated into the system chipset. CPU Pipelining Increases data throughput by allowing the CPU to start the next machine cycle before it finishes processing the current one. Burst Cache Module During a single machine cycle, a bursting CPU generates a beginning address and a quantity of bytes for the cache to expect. Then the CPU transfers that quantity of bytes as a single package, without needing to generate any intermediate addresses. Asynchronous Cache Module An asynchronous cache can generate wait states that tell the CPU to delay transferring information until valid data is ready to be transferred to or from the cache. 31 Chapter 3 - Using SETUP 3. Using SETUP The SETUP utility program allows you to customize the power-on initialization parameters of your computer's BIOS (Basic Input/Output System). You may need to use the SETUP program if you add components to your system. To run the BIOS SETUP program, press F2 during system boot. Once inside SETUP, you can reach different sections by pressing the right/left arrow keys on your keyboard. Inside each section, you can go into a subsection (indicated by a right-pointing triangle on the left side of the screen) by moving to it with the up/down arrow keys, then pressing the Enter key. Setup's five sections are Main, Advanced, Security, Power, and Exit. Each section contains topics you can view or adjust to suit your system's needs. SETUP allows you to customize various system parameters, although our technicians optimize them for your system as shipped. If you inadvertently change BIOS values that cause your system to malfunction, you can simply reload the original factory default settings from ROM by entering SETUP, then pressing the F9 key. Otherwise, you can load the most recently saved settings from battery backed CMOS by pressing F10. Within SETUP, pressing F1 toggles the General Help window, while the right-hand panel describes the function of the currently highlighted topic. To change your BIOS settings, first use the arrow keys to highlight the desired topic, then press the space bar or the <+> or <->key on the numeric keypad to rotate through the available options. Note: only an item whose label is surrounded by [square brackets] may be changed; values not in brackets can only be viewed. Once you've finished customizing your BIOS settings, press the Esc key a couple times to reach the Exit menu. There you can decide if you really want to keep your changes, if you'd prefer to return to the factory defaults, or if you want to go back to using your previously saved values. In any case, remember you can always change the BIOS settings again next time you boot up. 32 Chapter 3 - Using SETUP Main Menu Your system's BIOS settings were configured at the factory to maximize performance with the options you ordered. Generally, you need to run SETUP only if you install a new or different hard drive, if the onboard battery fails, or if you otherwise add to or change your basic hardware. SETUP's Main Menu allows you to view and configure several basic parameters, including system time, date, and daylight savings, Diskette A and B, system memory (RAM) timing, memory shadowing, boot sequence options, and video system type. The Main Menu lets you configure four PCI local bus IDE devices: · IDE Adapter 0 Master (Drive letter, capacity in megabytes) · IDE Adapter 0 Slave (Drive letter, capacity in megabytes) · IDE Adapter 1 Master (Drive letter, capacity in megabytes) · IDE Adapter 1 Slave (Drive letter, capacity in megabytes) Each of the four IDE Adapter subsections lets you view and customize the settings for a separate PCI local bus IDE device attached directly to you mainboard. The subsections are described on the following pages. SETUP's Main Menu also contains subsections for Memory Control, Memory Shadow, and Boot Sequence. Finally, System Memory and Extended Memory are displayed. At the very bottom is a chart showing how to navigate and change values in SETUP. 33 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. Daylight Savings Adjusts system clock for daylight savings time. Default: Enabled. 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. IDE Adapters (Four Provided) Each of the four IDE Adapter subsections allows you to view and change configurations of the IDE devices attached to your onboard IDE Hard Drive connectors, J7 and J8. The IDE Adapter subsections list the IDE devices that are currently installed. Your Primary hard drive (J7) is listed as IDE Adapter 0 Master. You can attach a second hard drive to the same cable as IDE Adapter 0 Slave, then two more devices on the Secondary connector (J8) as IDE Adapter 1 Master, or IDE Adapter 1 Slave. The following page describes the contents of each IDE Adapter subsection. Note: If you attach two drives to a single drive cable, it doesn't matter whether or not the Master drive is connected to the end connector. Just be sure that one drive is configured as Master and the other drive is configured as Slave. 34 Chapter 3 - Using SETUP Autotype Fixed Disk This utility detects and configures your IDE Adapter, if the device conforms to ANSI technical specifications. ZEOS drives are configured at the factory, so to add a hard drive you just run Autotype. If Autotype is successful, it will identify your hard drive type and display the drive parameters. Otherwise, you can select one of the established drive type numbers from the Type list, or select Type USER to set Cylinders, Heads, Sectors/Track and Write Precomp yourself (according to the information supplied by the device's manufacturer). Note: Don't alter drive parameters unless you change or add a hard drive. Multi-Sector Transfer Determines the number of sectors per block for multiple sector transfers. Options are Disabled, 2, 4, 8, and 16. Older hard drives (and even some newer drives) will not work properly if the number of sectors is set too high. Default: 16. Note: Before adding a new hard drive or formatting one from Zeos, first disable MultiSector Transfers, then format the drive, then run FDISK. Later, you can enable Multi-Sector Transfers again. Write Precomp Write Precompensation. In older hard drives, this setting tells the drive to apply a stronger magnetic field to inner tracks of the disk to compensate for magnetic drift. Your hard disk manufacturer's documentation should tell you if your drive requires this setting. Default: None (Disabled). 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. Default: Set at the factory. Video System This option sets the video type. It can be set to Monochrome, CGA 80 x 25 (80 column Color Graphics), or EGA/VGA (Enhanced/Video Graphics Adapter). Default: EGA/VGA. 35 Chapter 3 - Using SETUP Memory Control The Memory Control subsection lets you view and change DRAM (system RAM) Timing, enable/disable the L2 (Level 2) External Cache, and determine which shadowed upper memory regions (in addition to system and video) are allowed to be cached in a superfast (12-15ns) 256K or 512K SIMM. DRAM Timing Sets the upper limit for DRAM (system RAM) speed to 50, 60, or 70ns (nanoseconds). DRAM Timing must be set to match the speed of the slowest SIMM in your memory slots. Default: 70ns. External Cache Allows you to enable/disable the L2 (Level 2) External Cache feature. If the special Level 2 cache SIMM is present, it offers an ultrafast, 12- to 15nanosecond buffer between your CPU and regular (50-70ns) system RAM. Normally L2 cache speeds up your system, but because some software has problems with L2 caching, you may (rarely) need to disable the External Cache. Default: Enabled. Cache Memory Regions Allows you to choose which specific shadowed BIOS memory regions (in addition to System code and Video code) will be cached. Regions are identified by hexadecimal (base 16) addresses. Default: All specific regions Disabled. 36 Chapter 3 - Using SETUP Memory Shadow BIOS shadowing copies data from portions of the computer's slower ROM (Read-Only Memory) chips into much faster DRAM (system RAM) chips in system memory. This data can then be read more quickly by the CPU, so system performance improves. The Memory Shadow subsection lets you make certain regions of your upper memory (other than that reserved for basic system and video) available for BIOS shadowing. System Shadow This setting is not adjustable. System shadow is always Enabled. Video Shadow Enables/disables copying of the video BIOS into RAM. Shadowing the video BIOS code improves video performance. Default: Enabled. Shadow Memory Regions Allows additional specific memory regions (other than System and Video) to be shadowed in upper RAM memory. When enabled, any ROM data located in the specified region will be copied to shadow RAM when you boot up. Regions are identified by hexadecimal (base 16) addresses. Default: All specific regions Disabled. Boot Sequence Determines what drive the system checks first for an operating system. Choices are A: then C:, C: then A:, and C: only. Default: A: then C:. 37 Chapter 3 - Using SETUP Advanced Menu Warning! Setting these items incorrectly could cause your system to malfunction. Never needlessly change from the defaults. The Advanced Menu offers the following options: Large Disk Access Mode Lets you set your system to expect a large DOS hard disk, or some Other type of hard disk, such as expected by UNIX or Novell Netware. Default: DOS. OS support for more than 64MB This option allows support for more than 64MB of memory with operating systems other than DOS, such as OS/2 and Windows NT. On systems with more than 64MB of memory, set to disable for DOS and Windows, Enable for OS/2 and Windows NT. Default: Disabled. Plug & Play O/S Enables/disables peripheral add-on features for computers with Plug & Play operating systems. Default: No. Integrated Peripherals Lets you configure your serial and parallel ports, as well as your onboard floppy disk controller, your onboard IDE controller, your audio device (if present), and your PC's speaker volume. The following list describes each of these parameters. (more settings, next page) 38 Chapter 3 - Using SETUP Advanced Menu (continued) 1st COM Port When 1st COM Port (COM A) is set to Auto, the system will automatically set the interrupt and IRQ for that port. Otherwise this option allows you to choose (from a list) the interrupt and I/O address of the 9pin serial port. Default: Auto. 2nd COM Port When 2nd COM Port (COM B) is set to Auto, the system will automatically set the interrupt and IRQ for that port. Otherwise this option allows you to choose (from a list) the interrupt and I/O address of the 25pin serial port. Default: Auto. LPT Port Sets the parallel port designation. This allows you to specify the parallel port address and IRQ, which otherwise are factory set. Default: Auto. 39 Chapter 3 - Using SETUP LPT Mode Allows you to set the parallel port communication mode to match the capabilities of your parallel port device. Settings: Unidirectional, Bidirectional or Enhanced. Default: Unidirectional. Floppy Disk Controller Configures the onboard floppy disk controller to Primary, Secondary, or Disabled. Default: Primary. IDE Controller Enables/disables the onboard IDE controller, which controls up to four PCI local bus devices. Default: Enabled. PC Speaker volume Sets PC speaker to low, medium or high volume, or disables it. Default: Medium. 40 Chapter 3 - Using SETUP PCI Devices The PCI (Peripheral Component Interconnect) Devices subsection allows you to enable or disable the integrated SCSI and LAN options. Enable Onboard SCSI Enables/disables the built-in SCSI port, if present. Default: set at factory. Onboard Ethernet Enables/disables the onboard AMD Ethernet controller, if present. Default: set at factory. 41 Chapter 3 - Using SETUP Security Options The Security Menu allows you to password-protect system access, a way of safeguarding information. When passwords are enabled, users must type the proper password to access the protected part of the system. Note: 1. It's easy to forget a password, so we strongly recommend writing down your passwords and storing them in a secure place. 2. If you type the User password on entering SETUP, you cannot change the Supervisor Password or Diskette Access settings. Warning! If you forget the password, your system will not operate. You will have to completely clear the CMOS memory and reenter 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 Supervisor Password is Allows you to enter a system supervisor password. This password controls access to all features of your system. User Password is Accessible only after Supervisor Password is enabled, this allows you to enter a system user password. You can't use the User Password to alter the Supervisor Password in SETUP. 42 Chapter 3 - Using SETUP Password on boot When enabled, the system asks you for a password on boot. The system will boot only after the correct supervisor or user password is entered. Default: Disabled. Diskette access Active only when a Supervisor password is enabled, this specifies which level of password (Supervisor or User) is required on bootup to use the floppy disk drives. This can prevent unauthorized transfer of data. Default: Supervisor. Note: All diskette drive access can be denied (including system diskettes) by 1) setting a Supervisor password, 2) setting Password on Boot to Disabled, then 3) setting Diskette Access to Supervisor. Fixed disk boot sector When enabled, write protects the boot sector on your hard drive to protect against viruses. Default: Disabled. System backup reminder When enabled, this periodically displays a boot reminder message to back up your system. Options: Daily, Weekly, Monthly, Disabled. Default: Disabled.
