I don’t have the motherboard yet. Last I checked it was in new york so I should have it within a week would be my guess. But yes, that layout looks correct. I do not believe it’s a baby AT? Didn’t those have less slots? It’s possible that the same board was used by multiple manufacturers. So I …

Which motherboard do you use ? most 486 motherboard use 64KB ROMs which are very often compatible with 27C512 chips, but some socket 3 boards use 128KB chips of another kind (same kind as later pentium boards)

Really ? They seem to be some cheap Taiwanese brand, but not specifically PCChips/amptron/ECS/whatever else. As for the name, it's true, I still have to find an elegant way of doing that because for cases like PCChips there are dozens of names that exist ... We can't just add like 10 times the same …

Commate is Commel I think. They must have changed their name since the 90's As for DCS according to evasive (from nearly 18 years ago !), this is a reseller, not an actual board maker http://www.motherboards.org/forums/viewtopic. … ?p=52642#p52642

Well I guess you could always try to sacrifice a I/O card with that chip to replace it, it's up to you. Or maybe there are pin compatible chips ? Who knows ?

No, but I'm sure you can modify it (the source is included) if you know where the hdd controller's ROM is in RAM.

Yes. This one is pretty simple. It's the executable equivalent of using the debug command and writing few lines in there. It's copying the first 64kb of the bios, which works perfect for most 286/386 and early 486s. For newer stuff I'd recommend "uniflash" which I have used quite a lot

While making UH19 we noticed that some brands are actually the same. DTK is also Gemlight for example. And the "bottom" range of boards can be resumed to one brand : PCChips. Now ECS is a different story. As @dionb mentioned, quality changes over time. ECS made pretty good 486 boards in my opinion. …

For the unicore bios, try the password "otrebla" ? The archive was protected by that password so maybe the bios itself is using the same password ?

It depends of your budget and the period correctness you want to achieve. I don't think there were socket 370 pentium 3s in 1999 Imo a good amount of RAM for 1999 is 128MB. 256MB is you want to go overkill. For the amount of sticks, I don't think it'll change anything. This is before the days of …

For 1999, with Voodoo graphics and sound blaster, what you could have was : - A slot 1 pentium 3 (I don't know the speed that were available at the time but I'd say about 650/700MHz max) - A slot 1 motherboard with i440BX chipset - A 3Dfx Voodoo 3 3500 (3000 or 2000 can be bought for cheaper though) …
