So I have Edge3D 2200 card were the BIOS chip seems to have failed. I switched it out with a chip from a working 2200 and it now boots as it should.
My questions are:
1. Do anyone have the BIOS of a Edge3D 2200 card laying around?
2. How do I dump the BIOS if I need to? Preferably through software.
3. If it can't be dumped by software, then I got to dump with a EEPROM reader?
It is 99.999% sure that the bios can be dumped with a programmer, from the pic here I can see the chip is a 27C256 150ns - an one-time-programmable device. Piece of cake 😀
edit:
maybe this utility can be used: https://www.wimsbios.com/ajzchips/index.php
VGA Savebios.zip Saves a 32KB ROM image of your VGA BIOS
I'll try the software program first 😀
Cheers!

heh yeah, I like tinkering that's true 🤣
also bumping this thread in case anyone can provide a bios image for the nv1 vga 😀

I was JUST thinking the same thing: great idea 😁

Here is the file I got from the software Keropi linked to:
https://dl.dropboxusercontent.com/u/57506833/ … ons/VIDBIOS.BIN
Openening the file in Notepad provides some readable parts, so it seems to be the real deal. Still have to test it though.

This is what i read in my minipro program:

I know I'm bumping an old thread here, but I got myself a TL866II-Plus and I tried to write the attached BIOS file to a M27C512-10F, but that didn't work. Also I pealed back the label on one of my cards and its a ST M27C256B-12F. I've ordered some of those (10F version) and I'll report back when I receive them.
Also the original BIOS works fine in the reader (which causes the card to not boot), this being a Japanese card I believe its for NEC PC's.

Did you fill the whole 27c512 space?
It is 64kbytes so do a "copy /b 32k.bin + 32k.bin 64k.bin" and write the 64k.bin in the 27c512 chip

No, I didn't. I'm just getting started with the TL866, so I assumed the software would handle this by itself.

Can confirm this did the trick. The card now boots as it should 😀
Excellent 😀
