350 "bug": Just downloaded the 350 patch from hardware.pairnet.com Just for fun I compared the old binaries with the super-patch. Results: the two files differ in a single byte only, at byte location 36B5: Old bad IOS.VxD contains code 90 (=NOP), New patched VxD contains code 41 (=INC EAX)! Microsoft did a really hard "job". The piece of code actually is trying to get timer difference before and after a 1,000,000 LOOP to itself command, and to fix the timing problem they incremented something. The next byte is also NOP, so we can be sure that there is a room for one more INC command to fix the next "ourage" when K6 hits 600MHz...
