Deniz, the bios files are increased, I don't have those mainboards but, a few left. Those are i820 based P3C-2000 (SD-Ram), P3C-S (SCSI on board) and P3C-D (dual Slot 1). There are also BX chipset based P2B-S (SCSI on board) and i810 based P3W (SD-Ram) not in the list. You may add those as well if …

Pentium Over Drive processor is a better performer in general, but at specific software or games AMD Am5x86-P75 rarely performs better. Check the cache state of both. If Pentium Over Drive processor works at Write Through mode, AMD Am5x86-P75 may work better this time in general, if it works at …

For Windows XP (and XP x64) latest hardware among the Sandy Bridge and Ivy Bridge processors (for 1150 socket systems), there are also socket 2011 systems supported as well. So if you have a Sandy Bridge and Ivy Bridge based socket 2011 mainboard, you can install necessary software for the system. …

Not much happening here since I got another project that needs some more attention than this one. More on that later :) I got image files for Dos 6.22 and I found the orignal windows 3.11 installation disks in a box here. Also with Dos 5 and Windows 3.0 and some other programs from that time. …
Re: Which USB 2.0 cards for old motherboards
Posted on 2023-03-13, 18:43
VIA USB cards need special drivers. Search USB depositories. Some of 478 pin mainboards does not work with selected USB 2.0 and older controllers, but you have BX chipset. This chipset is automatically recognizable by Windows 98 and up, but have a try to load latest chipset software by Intel.
Re: CPU for Gigabyte BX2000
Posted on 2023-03-03, 10:51
Specific to Gigabyte 2000 and 2000+ mainboards there are dip switches. At Gigabyte BX2000.pdf, mainboard datasheet page 4 indicates, it is possible to adjust 33.3 MHz instead of 44.3 MHz by making adjustment on jumpers. Jumpers 5 - 6 - 7 - 8 if off, on, off, off makes 44.3 MHz at 133 MHz bus, but if …
Re: Modifying the POD83's voltage regulator for overclocking

I meant very old cars, 1900 around. Thanks for the info, it looks difficult a bit. I will see.... Yes, I think so, QVision 1280/E is also very expensive, finding a 4 MB Matrox EISA card is almost impossible.

Really good examples. But, using a real old car is something like, you can not drive it at roads. You need to have a special paper first, and it is for a short time only, for filming purposes or transporting etc. It can not give you the real comfort. My mom has a 1965 fastback Mustang, I have bought …

Can be, there must be have an issue.... But, the G400 card was working on PIII mainboards, as well as the motherboard was working with G550 and nVidia 6800 cards.

G400 did not run on Asus P4T-533C mainboard (it was a AGP 4x) a red protection and warning led was lighting nearby AGP Slot on mainboard with G400, but G550 successfully worked. I think there were a compatibility issue.

I currently own one Matrox G100 and one G550, many years ago I have a G400, but I have sold it because of not working on 478 pin mainboard. It has no 1,5 Volt compatibility. Thus it requires a Pentium III mainboard to run only. The G550 can work on 478 pin mainboard, so I have shifted them, many …

All the modification attempts are too risky, why don't you simple move to a Pentium III with a good AGP graphics card and go like that? Even an Intel i740 or an on board i815 graphics have Windows 3.1 drivers if needed. For engineers, the way taken from year from 1995 to 2000 is astonishing. ISA --> …

The Prosignia 300/500 has a different planar, but the CPU complex is identical with the XL. I swapped them so often, I still dont know what board originated where. The only difference might be the bracket, but I am not even sure about this. I do not remeber plugging a fan to the CPU board, only to …

There is no Pentium Pro to Slot 1 adapter left anywhere on sale at, eBay, Aliexpress, Newegg, Amazon etc. The Pentium Pro adapter can only be used with 66 MHz bus. Not all mainboards can support this fsb, like i815 and i820 chipset. The performance of Pentium Pro is up to 233 MHz with of the die 256 …
