What's missing here is the kernel/boot disk you are using to boot linux.
In the Slackware distribution, I believe there are 2 scsi boot disks
(maybe more).  Check the Installation or Distribution HOWTOs to find the
correct boot disk to use.  I believe all the SCSI boot disks have SCSI
CDROM support compiled in.  If you have linux working, try recompiling
a kernel with all the correct support (both for your particular SCSI
controller AND for SCSI CD-ROMs).  You might also check the symbolic
link that is /dev/cdrom to make sure it is pointing to the /dev/scd0
(I think!) device, or just try mounting the /dev/scd0 device directly,
as alluded to in an earlier response.  

If you haven't compiled a kernel before, get the appropriate HOWTO
docs and check the readme's in /usr/src/linux.  And don't have too
much fun without me.  Especially when you make 1 mistake configuring
the kernel and get to reanswer all the questions...

Hope that helps,

Mike Leiter

) I have a virtually the same problem with a CHINON 525 SCSI drive and Adaptec 
) 1522a controller.  The common elements to the above are that I am using EIDE 
) HDDs and SCSI CD-ROM.  Linux complains that it is not a block device or the 
) scsi bus times out.

) I am using the Slackware 3.0 November 1995 edition.

) The CD-ROM drive works fine under NT and WIN95.

) I have linux working by copying the software off CD using Win95, 
) booting from disk, and mounting the DOS drive.

) Linux works fine, I just can't mount the CD - which is a real pain.

) Any help greatly appreciated.

) Ben.
