My install of Mandrake 6.0 (on an AMD350, 96M RAM with 2 IDE HDs, 1
MITSUMI CR-2801TE CD-R 1 MITSUMI FX240S CD-ROM) failed to configure
the IDE CD-R correctly with SCSI emulation, but I was able to manually
mount both as IDE CDs.
The file: /usr/doc/xcdroast-0.96e/README.ATAPIgives directions for
re-compiling the kernel to:
4) In "Floppy, IDE and other block devices", disable "IDE/ATAPI CD-ROM
support" and enable instead "scsi emulation"
5) in "SCSI support" enable "SCSI support", "SCSI CD-ROM support" and
"SCSI generic support", everything directly in the kernel.
make boot returned an error that the image was too big, and something
to the effect of making more modules I went back into make xconfig, and
aggressively converted kernel build ins to modules, and managed to
compile a kernel that fit (now I managed to break a number of other
things, but that is a subject of a different post).
Now the CD-R and CD-ROM are configured a SCSI devices.
From the boot sequence:
hdc: CR-2801TE, ATAPI CDROM drive
hdd: FX240S, ATAPI CDROM drive
ide0 at 0x1f0-0x1f7,0x3f6 on irq 14
ide1 at 0x170-0x177,0x376 on irq 15

so the CDs are configured
and xcdroast finds the drives as both SCSI IDE in the section
SCSI/IDE-Info
but, if I try to mount either drive manually, I get:
[root@extralin /root]# mount -t iso9660 /dev/hdc /mnt/disk
mount: wrong fs type, bad option, bad superblock on /dev/hdc,
or too many mounted file systems
[root@extralin /root]# mount -t iso9660 /dev/hdd /mnt/disk
mount: wrong fs type, bad option, bad superblock on /dev/hdd,
or too many mounted file systems
[root@extralin /root]# mount -t iso9660 /dev/sda /mnt/disk
mount: the kernel does not recognize /dev/sda as a block device
(maybe `insmod driver'?)
[root@extralin /root]# mount -t iso9660 /dev/sdb /mnt/disk
mount: the kernel does not recognize /dev/sdb as a block device
(maybe `insmod driver'?)
[root@extralin /root]# mount -t iso9660 /dev/sdc /mnt/disk
mount: the kernel does not recognize /dev/sdc as a block device
(maybe `insmod driver'?)
[root@extralin /root]# mount -t iso9660 /dev/sdd /mnt/disk
mount: the kernel does not recognize /dev/sdd as a block device
(maybe `insmod driver'?)
[root@extralin /root]#
Now the SCSI emulation has been compiles into the kernel, but no harm in
looking at the modules. . .
[root@extralin /root]# lsmod

Well I am at a loss. Sorry for the length of this post, but I hope that
I have provided enough info so stat somebody can point me in the right
directiom. Thank you in advance. . .jrt
