I thought I'd try and see if the modded Bios I created (only partly my work) would recognise my 2400+ Thoroughbred "B" cpu in my KT7-RAID, and it did successfully.
I also tried a Barton but that was no go, I got a beep but no bios screen no matter what I tried. I will try and get hold of an unlocked 2600+ Barton on a 266fsb at some point
and give that a go. The 2800+I tried was a later fully locked cpu.
I also worked out what multi in the bios corresponds to what You actually get
BIOS MULTI= CPU MULTI
5= Does not boot
5.5= Does not boot
6= Does not boot
6.5= Does not boot
7= 15 for 1500mhz (100fsb)
7.5= 22 for 2200mhz
8= 16 for 1600mhz
8.5= 16.5 for 1650mhz
9= 17 for 1700mhz
9.5= 18 for 1800mhz
10= 23 for 2300mhz
10.5= 24 for 2400mhz (was running 3dmark99 until it crashed)
11= Does not boot
11.5= 19 for 1900mhz
12= Does not boot
12 above (12.5)= 20 for 2000mhz
"Does not boot" can be resolved by removing the AC cord for a few seconds, then holding down "delete" during boot, sets
it to a multi of 20 for 2000mhz
Anyway, here's the proof
