Quick question, perhaps not-so-quick answer.
I have a 16-bit ISA VGA video card. It has a Cirrus Logic GD5320 chip. It functions in both 8 and 16 bit slots without jumper changes, though it gets pretty glitchy in an 8 bit slot and I suspect one of the jumpers may help fix this but I need to know what they do.
On the back it is marked "CVGA-V3-256". The card's colour is sort of yellow, similar to two I/O cards I have from a company called JPN. However, Googling for this particular model finds one relevant result and it's useless.
Worth noting: the sticker on the BIOS chip says Cirrus Logic, so if it was made by a "rebrander", they sure didn't DO much to it.
Anyone recognize the naming pattern or happen to know much about JPN's product lines?
Better yet, anyone think they know what the settings are?
4 jumpers with 2 positions each (1-2, 2-3). JP6, JP7, JP8 and JP11.
There's also a 2-pin jumper, JP10. Neither JP11 or JP10 have shunts on them and the card has been working OK like this.
