here's what you need to do - during bootup, after you video card bios info, you will get the award bios screen - read what the bios revision is at the bottom of the screen - there will be a bunch of numbers, a date, and a 2 letter code, ie PO, QJ, RV. if yours is a p or n code then you should flash your bios to RV - fairly simple process if you follow abit's instructions.
after the flash - reboot as per instructions, and enter the bios and start setting things up. go into cpu setup: set fsb to user define, and select 133. multiplier to 7, set your pci divider to 1/4, agp to 2/3, agp mode to normal, leave voltage at 1.6 or 1.65, i/o voltage at 3.5(abit's def.). everything else at def. hit esc to get back to main menu. select cmos setup - here is where you config your ide drives - cd, etc. since you have a scsi drive just set whereever you cd is to auto/auto, make sure you a-drive is set right, esc. next advanced bios. obviously you are already booting from scsi, so that is fine, most def. in there are fine. esc. advanced chipset(i think) for safety set your memory settings to 3-3-3, precharge to disable, evrything else at def. (you can probably run that ram at 2-2-2, enable). esc.
save reboot - hopefully you are at 933. if you can't get past post, boost voltage to 1.7, then 1.75, etc. 1.9v won't kill you if you have good cooling but you might want to stop at 1.85. if all don't get you to 933, try decreasing fsb 1 mhz at a time (the beauty of the bf6)
good luck
ps. let us know how she goes - all the bios info i gave was from memory, but i f... with my bf6/650E (at anything from 866 - 936)constantly, and am fairly familiar with it, just the menu titles might be off.
