Correct, hdd=ide-scsi is in my lilo.conf file as append="hdd=ide-scsi" for the image I am loading. There is no other append for this image.
I actually had SCSI support added directly to the kernel and not as a module. Here's what I have enabled: SCSI support (CONFIG_SCSI) and SCSI generic support (CONFIG_CHR_DEV_SG). Now I am wondering if I should have also enabled SCSI CD-ROM support (CONFIG_BLK_DEV_SR) or SCSI disk support (CONFIG_BLK_DEV_SD) due to the block device errors. The reason why I did not set these is because the help for the generic SCSI specifically states: "If you want to use SCSI scanners, synthesizers or *CD-writers*" (my emphasis there) " or just about anything having "SCSI" in its name other than hard disks, CD-ROMs, or tapes, say Y here." I consider this a CD-writer and not a CD-ROM. The help file continues to give links for CD-writer software as well. So should I set one of these others as well? Maybe it needs to be clarified in the kernel help files despite the need for IDE-SCSI going away in 2.6 if one of the BLK_DEV modules need to be added.
While I am at it, Bill, ignore=hdd returned an invalid line error. Is this something special specific to SCSI modules?
Thanks, Steve

Steve,
So your kernel parameter looks like:
hdd=ide-scsi
Its in your lilo or grub.conf file right?
Did you by chance insmod ide-scsi ? lsmod to find out.
Did you include the ignore=hdd in your modules.conf?

Steve,
Are you sure the your kernel supports iso9660? Check
that
/proc/fs ( /proc/filesystems ) shows iso9660 in your kernel. After that I'd reset the system ( reboot ) to
make
sure that one of the drivers hasn't gone out to lunch.
( Or
you could do the rmmod/insmod thing ). Did you setup
the
kernel parameter for ide-scsi or did a script set it
up?
I haven't had this much trouble in the past with
mounting
drives. Did you build the kernel yourself?

Bill,
I checked out /proc/filesystems and iso9660 is supported.
I was able to mount a CD in my DVD drive and look at it with no
problems. I setup the kernel parameter for ide-scsi. I was following the
instructions located at http://www.troubleshooters.com/linux/cdrw.htm. I
built the kernel (2.4.23) myself. I rebooted but it made no difference.

Tim,
I tried the other devices you listed but got the same
error. Since I rebooted, I decided to go into Windows (ugh) which read
the CD-RW just fine.
After rebooting back into Linux I decided to take a look
at dmesg in case anything stuck out. Included are the bits dealing
with the CD-RW drive.
hdd: Hewlett-Packard CD-Writer Plus 9300, ATAPI CD/DVD-ROM drive hdd: attached ide-scsi driver. SCSI subsystem driver Revision: 1.00 scsi0 : SCSI host adapter emulation for IDE ATAPI devices Vendor: HP Model: CD-Writer+ 9300 Rev: 1.0c Type: CD-ROM ANSI SCSI revision: 02 ide-scsi: hdd: unsupported command in request queue (0) end_request: I/O error, dev 16:40 (hdd), sector 64 isofs_read_super: bread failed, dev=16:40, iso_blknum=16, block=32
These last three lines stick out at me. I'm guessing the
error at ide-scsi might be causing the other two and thus the
mounting problems, but have no idea what command it's bitching about.
Finally, since you might ask, here is the lilo entry: image=/vmlinuz label=Linux read-only append="hdd=ide-scsi"
Thanks, Steve
