Performance BIOS for AK31 V2.0 only		    AK31S907   07/03/2001
=========================================================================

Notes
-----
Use this BIOS at your own risk!!! Flashing the wrong performance BIOS on 
the wrong PCB version will cause total boot failure.

This performance BIOS is intended for advanced/power user use only, 
since this BIOS is specially tuned and for use in conjunction with 
"qualified" hardware devices which meets the performance BIOS requirement.

If after Bios flash, the system does not boot or give blank screen 
please clear CMOS, try other DDR and H/W devices otherwise please take
the original non-performance BIOS to an EEPROM programmer and have the
Bios Firmware reprogrammed. If for some reason the system becomes unstable,
please go into bios setup > Advanced Chipset Features > DRAM Clock/Drive
Control and set...

* SDRAM Cycle Length -> 2.5
* Bank Interleave -> Disabled
* DRAM Command Rate -> 2T Command

The user can fine-tune the above DDR SDRAM options in Bios Setup till
the system is stable and give optimal performance output possible.
