RE: AIC7xxx drivers Thunder K7x Pro .. booting off SCSI INSTEAD?

Rebuilt using the aic79xx driver from adaptec.. just realeased.. a day ago?

Configured it by modifying the aic7xxx drivers in the linux2.4.20 kernel

made my own kernel.. got it going..

Now my question is.. is there a way I make a rescue disk so if this fails..
I still have that scsi module?

Or more importantly.. how can I transfer everything over to the SCSI Drive..
including the boot sectors.. so I can boot off the SCSI disk.. instead..
removing the IDE DEVICE

Ack, sorry, answered a bit too quickly. I seem to have told quite a
few people recently-ish "use compact to get your SCSI working", and I
didn't check whether your chip was mentioned in the kernel docs before

As it turns out, it isn't listed or even mentioned anywhere in the
2.4.20 kernel source.

It seems your aic79xx.o module must have come from kernel 2.4.21. You
*might* be able to insert it by hand into the bf24 kernel - it's worth
a shot - but I wouldn't bet on it. I think you've got to obtain
somehow a 2.4.21 kernel image with aic79xx support enabled and use
that for the installation.

Quite how one goes about doing a Debian installation booting a
non-Debian kernel I'm not sure, but I'd try editing the boot floppy
image to include the 2.4.21 kernel, and doing the install-the-kernel
step of the installation by hand.

If you don't have another Linux box available to help you do this, you
could temporarily install some old half-gig IDE HD, do a bare-bones
minimum installation to that, then build a 2.4.21 kernel with aic79xx
support, transfer your minimal installation with new kernel to the
SCSI HD, reboot and use your favourite package management tool to
finish the job. Or you could temporarily install some old SCSI card
which is supported by the standard kernels until you can build a
2.4.21. If you have such a card around, this would probably be easier.
