I'm using WPCREDIT to optimize I845D (Asus P4B266-C) settings that are either ignored by my BIOS or unavailable and noticed Mode Select entry with it which has 000=post reset, 001=NOP en, 010=all banks, 011=mode register, 100=extended mode, and 110=CBR options. Chai, Adrian, or any Rojak have information regarding this, which option is best for performance, or is it even worth editing?
