by Greetings everyone:
I'm trying to get SCSI emulation to work with my 2.2.5 kernel so that
my new IDE CD-RW shows up as a SCSI device. However, no matter what I
try when I boot it shows up as IDE.
cdrecord -scanbus doesn't see the device until I do a
modprobe ide-scsi
at which point cdrecord -scanbus detects both IDE devices now as SCSI,
but I also get this Warning message with it:
cdrecord: Warning: controller returns wrong size for CD capabilities page.
dmesg now also detects the drives as SCSI.
scsi1 : SCSI host adapter emulation for IDE ATAPI devices
scsi : 2 hosts.

sr1: scsi3-mmc drive: 6x/6x writer cd/rw xa/form2 cdda tray
I can also mount both drives then as /dev/scd0 and /dev/scd1 ok.
My questions:
(1) Is it possible to set things up so that the IDE devices are seen
as SCSI devices automatically without having to manually do a
modprobe?
(2) What's with the warning message?
I've read the CD-Writing-HOWTO but the section dealing with 2.2.x
kernels isn't that clear to me. I've modified my kernel as suggested
by that document.
I'm stuck. Any suggestions?
Thanks,
Esmail

My system:
RedHat 5.2 with upgraded kernel to 2.2.5
Dell Dimension R-XPS 450 with (PII 450MHz 256MB)
IDE IBM-DTTA-371290 drive
SCSI SEAGATE ST32155W
IDE NEC CD-ROM DRIVE
yesterday I added a Philips CDRW 400 series 4x4x24 drive
IDE PHILIPS PCA460RW
In addition to the standard IDE controller that came with the system I
also have an Adaptec AHA-2940 Ultra SCSI controller.
