Right, where to begin.
I have a SIS 471 based 486 board, with a soldered on VIA VT82C42N keyboard controller chip, unfortunately, when I try to boot my system with this board, I get a keyboard error during POST. I know the keyboard works fine on several other motherboards, so it shouldn't be that. I've had the SIS motherboard go through POST a couple of times, but the keyboard doesn't work.
Is it possible to swap out these directly soldered onto the board chips, or are there multiple layers to these old PCBs?
The motherboard in question is a "Iston Corp." S486G Green Motherboard. After years of looking, I finally got hold of a manual, so it was rather annoying when it turns out to not have a working KB chip.
