Re:GeForce 6800 GT but no display... - 2005/12/20 07:41 Well, no luck. The attachment appears to be a standard version of NVF 5.15 that still gives the same unsupported EEPROM error.

Other ideas?

Only other thing I can come up with is find the elusive "STRAP_SUB_VENDOR pin" and ground it as per the romstrap option. Not a darned clue as to where this is.

Re:GeForce 6800 GT but no display... - 2005/12/20 14:20 Well if your chip really is M25P05, it should display a device id of 20,05.
Getting a device id of 20, FF is not good, as FF is generally a sign of something read wrong.

Re:GeForce 6800 GT but no display... - 2005/12/29 08:40 *Sigh*

Well, I can only think of two things.

1) Repalce existing 25P05 chip. Cheaply available from Mouser.com if you have decent soldering skills.

2) Visit the following sites:
http://www.st.com/stonline/products/literature/an/8354.htm
http://www.st.com/stonline/products/literature/an/11036.htm

Setup a *nix system you don't mind accidentally frying and write a program that uses the provided libraries (which I'm waiting on ST to reply with the location of the files) to manually erase and reprogram your EEPROM.

I'm going with option #1. This project appears to be heading closer and closer to "FUBAR."

Re:GeForce 6800 GT but no display... - 2006/01/02 17:01 No luck. Still gives (20,FF) with a new chip. Looks like the one I have might be hosed.

Re:GeForce 6800 GT but no display... - 2006/01/11 19:14 Mine is

Because mine won't work doesn't mean you can't get yours to work, but it definitely looks like they won't.

Bummer.

Re:GeForce 6800 GT but no display, even tried BIOS flashing? - 2006/01/31 03:11 I believe that my power supply is the problem I have the +12V at 8Amps and I did not known before. PNY, one manufacturing of shit.

That is not an issue of PNY, it is NVIDIA that make the GeForce 6600 series of chips and they require enough Amps on the 12V power rail, which is clearly stated. So basically blame it on your crappy power supply and that one is not made by PNY and they don't make power supplies...
