Re: [parisc-linux] FW Scsi support?

There have been some fixes to the kernel since the CDROM image was made
to get the U2 IO controller working correctly.  Also, I still need to apply 
the attached patch to get my C180 working.  The C160 should be the same as
C180 except for the frequency.  The C100 uses a PA7200 CPU instead of
PA8000 CPU and will not work with my entry.S changes, but may work if you
remove that portion of the patch.

My CDROM is not fastwide SCSI, but the kernel does detect the fastwide SCSI
harddrive.  I boot by LAN, but am able to mount CDROMs.
