I can't help but notice this whole Right to Repair argument has reduced the quality of the conversations on this thread. It's also pretty clear that none of the parties will be able to convince the other, making the arguing process useless. Maybe consider going back to a relevant topic, before …

It's made by Lucky Star, possibly named 486DXA. There is no info about it on the internet it seems.

You could try a few other BIOSes for the 580VPX chipset (that's the chipset on the M573), just make sure to match the Super I/O chip. I've also added those BIOSes from elhvb on UH19. http://www.win3x.org/uh19/motherboards/4165 EDIT: for the OP, a photo of the board would be appreciated.

I tried Navigator 4, but I couldn't view any of the search functionality. Could just browse by letter. In IE6 it appears to work (IE5 as well probably as you say), but just wanted to check on any cutoff point from a development perspective :) Internet Explorer 4 for Windows 95 is the oldest …

Either 27SF010 or 27SF020 should work, difference between them being the 010 is 128KB while the 020 is 256KB (so you'd have to write that image twice to fill the whole space).

That chip is just a backup BIOS, Gigabyte dubbed it "DualBIOS". You should be able to add an ISA slot, the resistor packs are there. Same mod can be done to a 7ZXE. EDIT: I was looking on the right side of the image, where you have another IC missing (that one is the 2nd BIOS :P) ; only way to know …

This is a really cool find! There is nothing like it in UH19 yet, but based on the BIOS image you attached, I was told its a UMC 480 clone. Will be digging more for info.

Try the attached BIOS image, I dumped it from my non-working board. Looks exactly the same as your one, although mine is missing the correct KBC. Not sure if that is what prevents it from booting, might be something else broken as I got it in a non-tested state. Could you take a photo of your board …

Thanks, but as I wrote, I tried several different PCI video cards and 2 different ISA cards, in all of the slots- and none of them works now. I failed to notice that in your original post, my bad. As for why it goes to FF with floppy, that's because it boots normally, but without a video adapter …

Try another video card, it doesn't seem to like the one you used for some reason. Also try an ISA card if you have one.

This reminded me, I had a Laserjet 4P a while back. That thing was heavily abused, it had a worn out main gear (the one that rolled the paper), the toner cartridge had to be jammed with an object to sit properly inside. Yet it refused to die, was still printing perfectly, without any horizontal/ …
