D975XBX2 can't boot after FSB increase

[francois methot]

It happen before because I did a big jump for OC the FSB frequency...I had a second mobo and change it.

Then, I was running fine and stable on the second mobo at FSB 333MHz with 667 MHz memory.
I decide to try 2 stick of 800 MHz memory. I had in mind to slowly increase the FSB to 400 MHz and match the new memory.
Reset back all OC to stock and start increasing the FSB by step of 5 MHz starting at 266 MHz.

Suddenlly, the computer did not boot, no post.
I try a very long reset, remove the battery. I try to boot with floppy to recovery the bios, but cannot load the floppy!!!

Is it dead?
Can I ship my first mobo somewhere to fix that problem?

Any beeps or indications at all?

Seems strange that it would just quit without letting you reset c-mos......

Are there two resets by any chance, and you're using the wrong one? (My board has a "hard" c-mos reset, and a "return to last known good post" reset, you want the "hard" one).

A floppy boot for bios flash won't do you any good if it won't post at all. (do you have an internal floppy or a USB one? ).

Unfortunately, I can't get on it tonight, but tomorrow morning I'll write up a quick and dirty step by step guide to attempting to bring back a dead board so don't give up just yet.

(If all else fails.... you can always order a new bios chip or get your old one reflashed).

There is a 3 pin header comfiguration jumper.

Normal
Password Recovery
Recovery

...I never tried the Password Recovery: So I try this configuration.

I was able to go inti BIOS with this position...put everything back to stock a reboot .

I am OK now.

Thank you

Good to know.

Great to hear! Go have a beer and a smoke now ;-)

I haven't forgotten the bios recovery guide I promised (you don't need it, but others might be able to use it). It's just taking a little longer to put together than I thought it would.

I should have it done before the end of the weekend.
