OK, I've been at this for around 2 years!
I have a P4I875P Dragon2 Black Label v1.0...what a name!
The Problem: BIOS is missing the 1:1 memory ratio from the menu!
The only way I can get my RAM to run at 200MHz (DDR400) is to install an 800 bus P4 and use automatic configuration. I know this because I happen to have an 800 bus P4 sitting on my bench!
If I install a 533 bus Celeron D, for example, I cannot chose the 1:1 ratio manually, it simply doesn't exist.
If I set the RAM divider to "Auto" with the Celeron D at 200MHz (800 bus), the board chooses 4:5 CPU:DRAM and forces DDR500, something that doesn't work with my RAM.
This isn't the first thing I've tried to change in this BIOS: Even unhiding hidden options hasn't worked. I've tried ModBin6, AwardMod, etc. Programs that appear to work don't actually save the settings.
This is Phoenix AwardBIOS v6.00PG If anyone knows a tool that actually works, or a way to make one of the tools I've already tried work, please let me know!
If anyone would like to play around with this BIOS, it's located at:
