并优化下BIOS：

这些设置是由著名的Omega显卡驱动的作者推荐的，我试了一下，WinXP sp2开机动画由十三圈减为3圈半（删除\Windows\Prefetch下所有文件也可达到同样效果，但这次没用）。

PERFORMANCE BIOS SETTINGS

Use these settings in your BIOS along with the OMEGA drivers to get the best performance possible out of your video card (this settings are not avaiable in all motherboards, use only the ones that fit your BIOS):

Fast Gate A20 Option : ENABLED

Video BIOS shadowing : DISABLED

Video BIOS cacheable : DISABLED

xxxxx - xxxxx Shadow : ALL DISABLED

IDE prefetch mode : ENABLED

Init Display First : AGP or PCI (SELECT YOUR CARD TYPE)

IDE HDD Block Mode : ENABLED

IDE 32-bit transfer mode : ENABLED

Assign IRQ for USB : DISABLED (UNLESS YOU USE USB DEVICES)

Assign IRQ for VGA : ENABLED

PCI/VGA palette snoop : DISABLED

PNP OS Installed : ENABLED (WINDOWS XP CAN HANDLE PNP BETTER THAN BIOS)

Resource Controlled By : AUTO (UNLESS YOU WANT TO MANUALLY ASSIGN IRQs AND DMAs)

AGP aperture size : 256 (USE LOWER value IF YOU HAVE TEXTURE PROBLEMS)

AGP master 1 WS write : DISABLED ***

AGP master 1 WS read : DISABLED***

Bank 0/1, 2/3 DRAM timing : TURBO ***

CPU to PCI write buffer : ENABLED

Delayed Transaction : DISABLED ****

DRAM speculative leadoff : ENABLED ***

DRAM Data Integrity Mode : NON-ECC (UNLESS YOU HAVE ECC MEMORY)

Delay DRAM read latch : (THE LOWER, THE FASTER) ***

Fast Writes : DISABLED (ENABLED FOR RADEON 9600 OR ATHLON64 SYSTEMS)

Memory parity/ECC check : DISABLED ***

Passive Release : DISABLED

PCI Concurrency : ENABLED

PCI master 0 WS write : ENABLED ***

RAS active time : (THE LOWER, THE FASTER) ***

RAS to CAS delay : (THE LOWER, THE FASTER) **

Read around write : ENABLED

SDRAM Bank Interleave : 4-bank/way

SDRAM CAS Latency Time : 2 **

SDRAM cycle length : 2 **

SDRAM Precharge control : ENABLED

Spread spectrum (modulation): DISABLED

System BIOS cacheable : DISABLED

Video RAM cacheable : DISABLED

8 bit I/O Recovery Time : 1

16 bit I/O Recovery Time : 1

Turbo frequency : ENABLED

** = ONLY IF YOUR MEMORY SUPPORT IT, OTHERWISE USE THE NEXT HIGHER value

*** = WILL IMPROVE SPEED BUT DECREASES STABILITY, IF YOU HAVE PROBLEMS, CHANGE IT

**** = ENABLE IF YOU EXPERIENCE PROBLEMS WITH CREATIVE SOUND CARDS

These settings should increase you framerates with your video card, if you want do a benchmark before and after the changes, it will give you a good idea of the gain obtained.
