These old PCBs can have subtle damage like cracked traces or vias that are rather difficult to find. It's possible, and a good project for someone who has the patience to go slow and can switch to other things when it's not going well. Otherwise it can be pretty frustrating. What I do with such …

UR received another update recently! It doesn't contain new features, its more of a user interface polish: new SVG icons, tab system for the board pages, etc. Filename 1.png File size 62.38 KiB Views 1066 views We have as well turned all the images in the right orientation (no longer upside down).

Awesome, thank you!!! I think I might have described things poorly, so a few notes on the diagram image: I think this board has no cache on it. Mine has a 40Mhz xtal on it (20Mhz CPU) SL1 is actually SL17, SL1 is the 8-bit ISA on the left of it. Apart from those minor details, it looks just perfect …

I'm still suspicious of the missing/cracked tants that you've found. But also might be worth checking the pins on the that 443 closely to check for any soldering issues. From the photo it looks like there's something odd on pins 61&62 which are the crystal connections. Those "bridged" pins go right …

To make things clear, a proper chipset database is now on the to-do list for UR, with images and documentation. When will it be ready?, hard to say. We have lots of other things which have a higher priority to implement right now, but it will be coming eventually.

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.
