Thanks for that, and yeah, it seems to be rather involved for just a bit of overclocking. If I had a spare I'd consider giving it a shot, but I'm not great at soldering as it is, so I'll pass. I figured out it's AMIBCP 7.5 that you need to look at the BIOS, and indeed there just isn't any options in …

K7S5A-Pro CPU Multiplier options?

Hi all, I've recently put together a build revolving around an ECS K7S5A-Pro. I know ECS's reputation, but I actually quite like this board and it's been quite stable in my experience. I'm using mobile/embedded CPUs to benefit from the lower power draw, and I'd like to overclock my Geode NX1750. I …

I haven't swapped back out to the 95 card but suffice to say it's not quite as simple as just swapping the card. After pondering this it does not make much sense as all my W9x/WMe system are multi-boot with just one SD card/SSD. I usually put W9x on a FAT16 2GB C: then have NT4/W2K/WXP/2K3 on NTFS …

Thank you for for confirming [Serial] triggered the issue, in the attached SIV32L 5.68 Hope-06 I hope I have fixed this, have I? If not you could do Menu->File->Save->Save Selected and deselect [serial] to circumvent the issue. It's not that big of a deal honestly. I just reboot and it's fine. …

Checking the CPU frequency under the help menu using DIV just said it didn't support RDTSC. [...] I suspect it's Menu->Hardware->H/W Detail->Serial that triggered the serial mouse lockup, is it? If so I will try and figure out why and adjust things. Yup, just tried it and sure enough that's exactly …

I don't have info for detecting 486BL or 486BL2, but 486BL3 has MSRs. BL and BL2 may, but I'd have to research or test that. Mine is actually a BL3! It's just underclocked with a modified BIOS to set the multiplier to 2 instead of 3 so I could reliably get it to run with a 33MHz bus. Sorry for the …

Technically the CPU is underclocked now at 66MHz but as you can see from the second screenshot, I …

But when I set the jumper for a 33MHz bus, it doesn't even POST -- does anyone else here have one doing that speed? How did you do it, is there something I missed?The …

Well, the YMF744 is happiest with DirectX 7 according to its latest drivers from what I can tell. I left it at 8.1 because I have a few DX8-era games installed (Max Payne, The Sims, etc) that can run on fixed-function cards but otherwise require the updated libraries. The Audigy2ZS is just kind of …

The way I found that seems to have done the job was to uninstall DirectX entirely using 98lite, which I had installed so I could more surgically remove certain things I don't need like System Restore, the Task Scheduler, so on and so forth.

Well, yeah, but if I swap the card for something that can survive just fine on DirectX7, then it stands to reason that I could downgrade the DirectX version without any trouble provided I did it right. Is there a procedure for that or is it just "copy the contents of the cab over C:\WINDOWS\SYSTEM …

I have a Pentium III 1GHz build with a Voodoo3 3000 and Audigy2ZS running Windows ME. As part of the driver install for the Audigy2, the wizard upgraded my version of DirectX to 9.0a with no option to cancel. This caused issues in a few games -- as far as I'm concerned DX9.0a is a glorified beta …

The UM480 variants all seem to lock up with my GA-486VM. The variant I settled on earlier in the thread comes the closest to working completely -- it detects the CPU fine, detects the proper amount of RAM and L2, and then locks up before I can even get into setup. I'm assuming it has something to do …

For some reason I have it in my mind that I could replace the 8Mhz 286 chip with a 12 or 16Mhz CPU, but that might not be possible. Does it matter for EGA games? I don't know. Be careful with that line of thinking. I'm not sure the original AT had decoupled the CPU from the expansion bus yet -- the …
