BIOS Updates forum

There are two known possibilities in supportbios.info:

Perhaps googling for the filenames might help.

Doesn't it have the typical lid you simply unscrew off?

Known issue with some Compaq laptops. I've had that very same issue with my Armada 110 and solved it by connecting an external keyboard, turned it on, hit F10 at POST, save&exit, shutdown, disconnect the external keyboard, and voilà... It fixed the problem.

Sounds like a corrupt BIOS

Have you tried disconnecting HD and CD except the FD to try a possible reflash if the latter is successfully accessed?

I have a feeling you'll have better luck Googling for the info...

Why don't you tell us what mobo you have, what you've done, what versions of flashers you're using, etc.?

Tried looking here?

You might be able to get into bootblock mode (Recovery mode) with the appropriate jumper...

Have you tried clearing CMOS just in case?

I'd try getting it flashed first...

Be careful... full speed implies full power which your mobo's VRM may not be able to provide...

I have several Adaptec SCSI controller cards, one of which misflashed and I've spent a lot of time discovering how to revive it, but to no avail

The only solution could be to piggy-back flash or simply carefully replace the BIOS chip (not at all easy).

Have you tried emailing HP?

If your screen boots blank, then it isn't an OS problem... Try flashing to the latest BIOS with your previous processor.
