Thanks PC@LIVE, yes any CHKCPU report is welcome. :) About the really Vintage PCs, does any of you have a 8086/8088 system available to test CHKCPU on? With the unusual high speed reading on konc's V20 CPU, I'm curios what the original 8086/8088 would show. ;) Thanks, Jan If none has one handy I'll …

Hey Jan, how hard would it be to make it colorful like memtest86+ Hi Shere478, actually I have no idea. I never did that kind of programming. Unlike full screen DOS programs that control every element on the screen directly, CHKCPU is a pure text-based tool that sends it output to DOS which in turn …

Actually, its the possibility to set 6x (or 2x) that I'm after. The BIOS is clearly capable of controlling all three BF lines, because it can set multipliers above 3.5x. But from the 8 possible combinations, only 4 can be selected in the BIOS Setup. These are X3.5, X4, X4.5, and X5. The logic the …

Hi Henkdrik, thanks for the Debug dumps. It makes the issue crystal clear. The values from the BIOS Data area show me that the CPU type and multiplier setting are correctly detected in each case, but that the FSB detection is incorrect when the multiplier is x4. In that case the BIOS thinks the FSB …
