If your ide-scsi module is not working, or cd r-w rom is not being
recognized.

The try this.

Recompile the kernel in make menuconfig in /usr/src/linux

Invoke scsi emulation as a module in ide-ata-atapi block devices
section, but put enhanced IDE and Atapi CD-Rom support as in-kernel
compilation.

So ide-cd and ide-mod will NOT be modules but WILL be in the kernel --
AND ide-scsi WILL be a module.

Then go into SCSI and invoke all sCSI options needed for CDROM and
disk into the kernel, not as modules.

SCSi Support #would be module scsi_mod
SCSI disk support #would be mod sd_mod
SCSI CD-Rom #would be sr_mod
And SCSI generic #would be mod sg

All 4 above go into the kernel as compiled-in.

Turn on "set version information on all module symbols" in loadable
module support.

Save configuration.

make dep, make clean, make bzImage, make modules, make modules_install

cd /arch/i386/boot ... cp bzImage /vmlinuz.cdr

put vmlinuz.cdr in lilo.conf as an image with a new label, say
linux24cdr and close lilo.conf

Now go into /etc/rc.modules and turn off all
loading of scsi modules except ide-scsi and scsi_syms

Go into /etc/modules.conf and put in these 2 lines.

alias scsi-hostadapter ide-scsi
options ide-cd ignore=hdc # that could be ignore hdb.
# that if there is only one cd drive.

And in lilo after the boot prompt you put
append="hdc=ide-scsi"

run lilo and reboot.

It might work.
