memory is on

[Ronald G. Minnich]

memory appears to be working on my 440gx. Next step is gunzipping linux
to high memory ... then jump to it.

stupid question.

Wont the bios be useless if one wrote an "bad" kernel on it?
If one cant boot from it, than it is impossible to correct it..

good question.

This is not a stupid question, it is a good question.

It's not a problem. I'm writing lots of bad bios'es at the moment. When I
do, I jumper over to bios recovery and that will allow you to recover to a
good BIOS. So there's no real problem.

Niklas Ekström wrote a program some time ago, loadbios, which loads a bios
from a file to the memory from 0xe0000 to 0xfffff on some intel pcisets.
It can easily be adopted to other chipsets and it's quite small.

Loadbios is available on the OpenBIOS homepage,

Quite true, which is why the "emergency recovery procedure"s are
vital.  Like on Ron's Intel L440GX+ boards, he puts in a floppy withthe
flash program and the old Award BIOS, sets a jumper, and the board loads a
minimal BIOS that can read and understand a floppy disk and then run the
flash utility.

Then again, not all recovery procedures are as good as this.
