Don't put it in /research -- after all, this isn't research (research are
simulations and the like, this is REAL :)).  Anyway, large attachments
don't work on the new list, so you should just make a driver tree and put
it there, I guess.

Sure :)

I have a VERY old printer, a Star LC-10 9-pin dot matrix thingie.  :)

I will do so, as soon as it's in CVS.

>And your SCSi controller? What about?

I've figured out the problem, and I've figured out how to solve it, but in
order to solve it I need a CD with RedHat Starbuck (5.9) and I can only get
it on thursday, so until then I can only boot from my old 250mb linux
partition on my IDE drive.  The problem is, the driver for my SCSI
controller (AMD 53C974) is alpha and hasn't been updated since 1995.  My
BIOS for some reason gives the SCSI controller the same IRQ as my S3 SVGA
card.  I don't think windows has any problems with this (haven't tried but
that appears to be standard), but linux apparently (perhaps due to the old
driver) can't handle the IRQ sharing and the SCSI goes completely crazy.
My computer has an HP BIOS which doesn't support manually assigning IRQs...
The solution is to manually change the INTERRUPT_LINE PCI register in the
S3 at boot time, but that is only supported on the new kernels (2.1.82+) so
I have to get a distro based on the 2.2 kernel.
I'm going to be running fine as soon as I can get starbuck.
