A while ago Abit posted a BIOS update (3R) that would allow the use of an Athlon 1.4, 200mhz. Supposedly, you must leave the processor LOCKED in order for it to boot at 1.4 ghz.
More recently Abit release a BIOS update for the KT7A(-RAID) that will allow the use of XP processors. Since this update works only for the 1.3 version of the KT7A one would conclude that it does not work for the even earlier KT7 board.
Would you like a Quarter Pounder?
No, thank you. Just give me the BIG heatsink. It's an Athlon.
