I just ordered all of this stuff for ~8EUR shipped. I don't know if anything will work, I can clearly see that there are some chips missing, but i think they can be replaced really cheap by ordering them from aliexpress (that pentium mainboard is probably missing a chip manufactured by SEC which is …

I don't think so, here is archived FTP index (downloads probably don't work anymore, but you can google file names) http://web.archive.org/web/20030904103349/htt … ish/index-e.htm i think that PB4 is the oldest one.

I also have this mainboard and using some tricks, I managed to convert that manual to a suitable format some time ago. I printed it on a 'virtual printer' in Windows 98, then reversed and scaled the pages on my modern PC. And that manual doesn't say P4B, it says PB4.

Thanks for advice. Yes, i tried every slot but it didn't work. I did the testing and noted voltage drop values (i can compare that with working mainboard, but i'm not sure if it will help). Here is what i measured. There are no unconnected pins and most of pins have ~650mV voltage drop. But some of …

Hello, few months ago I got an untested Am386DX-40 mainboard (Unichip 367c, or 386WB), which apparently had suffered a battery leak. It didn't turn on, it had some traces covered with rust and green substance. I washed it in distilled water with citric acid, then cleaned it with alcohol but it …

5V rail is used for PCI bus power, disks and for CPU voltage regulators (but if mainboard has the ATX12V connector then 12V line powers up the CPU). I don't know how accurate or correct are my calculations, but I usually check TDP of a processor and treat it like power consumption; Duron Spitfire …

I am trying to make an 100MHz IBM 5x86C (model 5x86-3V3100GF P50J12) work in ABIT PB4 rev 1.3 mainboard. It is a pretty late PCI board with FinALI chipset and has jumper settings for Cyrix Cx586 so it should be compatible. 5x86c.jpg But there was one problem, PCB with this CPU was too wide and it …

All right, I had some problems, but now everything is almost OK. After I had success with Omega drivers I installed K6-2 533 CPU again. And screen was distorted, like it was before. So i tried K6-2 500 and almost all of distortion was gone, but there was still some. Then I tried K6-2 350 and …
