The BIOS contains "SUNIX SUN-4310". On the ROM sticker is "Name 4310". And the card's layout matches the layout in the 'SUN-4310' user manual at [here].
And so I added the ROM image to the Sunix section of [here]. Thank you.
1. There was no techway logo on the bios eprom
2. PCB color is different.
3. And now you gave me the manual, so probably its a sun / sunix controller card instead.
Thing changes when you have seen this:
Yeah rom stickers looks different...
But PCB color looks still that same (the darker green)
( yes that card on the right i have still to clean)
Left only have to add 2 new 100pF ceramic disk capacitors, that broke during clean (they where brittle.)
