bluejay Posted June 18, 2021 Share Posted June 18, 2021 Need some help identifying the PC/104 VGA card on the left. I’ve googled for PC/104 VGA cards, and although I found a few that used the same controller chip, I couldn’t find the exact one. Any ideas on what it is?

wierd_w Posted June 19, 2021 Share Posted June 19, 2021 Dont have an exact one, but I would think it would work with generic drivers for that chipset. Lots of generic 1mb VGA cards were made for early PCI systems with that chipset, which is what I presume this PC-104 board is meant to work as. Positive ID shouldn't be necessary, no? 1 Quote Link to comment Share on other sites More sharing options...
bluejay Posted June 19, 2021 Author Share Posted June 19, 2021 (edited) Oh, it isn’t necessary, but I wanted to have its data sheet so I can figure out what all the jumpers do and why it isn’t making the computer function when it’s plugged in. Although from the symptoms and the given information, I’m about 95% sure the power supply can’t handle the load, as the computer itself needs 720mA, and the power supply is 700mA.

Keatah Posted June 19, 2021 Share Posted June 19, 2021 (edited) Amp up the supply and see what happens. The graphics chip can consume around 230mA MAX. Add another 20mA because we're conservative. And don't forget the support chips, and any video memory and glue. You can also look at the jumpers, trace them back to the main 65545 chip (if they go there), and look-up the function in the pinout chart. I've done that on my Cirrus Logic 54xx and S3 Virge boards.

bluejay Posted June 19, 2021 Author Share Posted June 19, 2021 I probably have a 1A power supply I can use somewhere. I don’t have a VGA monitor to use at this very moment so it’ll have to wait a couple weeks. I’ll take a look at that data sheet though, thanks!
