Chapter 2 Hardware Installation    Electrostatic discharge (ESD) can damage your processor, disk drives, expansion boards, and other components. Always observe the following precautions before you install a system component. 1. Do not remove a component from its protective packaging until you are ready to install it. Wear a wrist ground strap and attach it to a metal part of the system unit before handling a component. If a wrist strap is not available, maintain contact with the system unit throughout any procedure requiring ESD protection. 2.          !"# $ !"#     #%& #%&' $( $& # !) *+ , , #* ,"!

By this smart design, it would be more convenient to clear CPU frequency setting. For using this function, you just need to press key first and then press Power button at the same time. Note that do not release key until POST sreen appearing. "  ! !"# = 44$; '/ 1 ; ' : /   The specification of AGP is maximum 66Mhz clock.

Both of these two fans connectors can support hardware monitoring function, however, you can only use the CPU FAN connector to control the fan power ON/OFF. &# #%& 4$ '   '   %  ' $ #%&' 4$ '   '    "( #)&* A ' ( '  & '  . ! &6 '   '   &  % + ,/ , .  , -"( ?*+ *+ *+ / ' . . $ / B >!B '     -$$ 2!$ 3 2!$< 2  2!$ (45 -$$' 3 $ $ < /01+ =2!$ 2  2!$ / 2!$  This motherboard does not support EDO DRAM. -$$  .
