No common CD-ROM drive was detected

[duffrecords]

I would like to install Ubuntu Studio 7.10 because the real time kernels found in Hardy and Intrepid are said to have worse latency or are more resource-hungry than the earlier kernels. However, I can't get far in the installation process because it can't detect my DVD drive, which is a SATA device. This is the error it creates:

No common CD-ROM drive was detected.

There is no CD-ROM and even if there were, the Ubuntu Studio installer only fits on a DVD. I've read several forum posts which advise going into the BIOS and changing the SATA operation mode to RAID instead of IDE or AHCI. I've tried all three options but the installer still fails to detect the drive. The other solutions I can think of are to use an external USB enclosure for the drive (which I don't have) or to boot over the network (although the same people who posted on these forums reported the older kernel did not recognize their network card). The installer does give me the opportunity to supply a driver via floppy disk but I don't know which driver that is or where to get it. My DVD drive is a Samsung SH-S223Q and in Hardy Heron it is identified with no problem as /dev/scd0 and mounted as /media/cdrom0.

I also read a post that said to
modprobe ide-scsi and try to detect the drive again but I received this response:

FATAL: Module ide_scsi not found.

I had this issue too, I solved it by hitting ALT + F2, Enter to activate the console, and typed the following:
modprobe ide-scsi
modprobe ide_generic

Then I went back to the first terminal, ALT + F1, and had it detect the hardware again.

Just an FYI, I discovered the above only worked with Hardy Heron. I couldn't get it to work with Intrepid Ibex

This seems to be fixed in releases such as Ubuntu 9.04 and Debian 5.0, the latter of which I'm using now.

Ah, that's interesting - I had the same problem with both the 8.10 and 9.04 alternate CDs, but the 8.04 alternate CD installer detected the DVD-ROM drive with no problem (and all 3 CDs booted from that drive). I've started an install of 8.04, but I'll try aborting it and see whether your method works with 9.04.

More later...

No, it didn't work on my system with either 8.10 or 9.04 :( Back to 8.04...

But having installed 8.04 I was able to use the 9.04 install CD to upgrade - could have been worse...

With Xubuntu karmic-alternate-i386 (alpha-6), I get this problem.
Both of the suggested modprobe commands failed.
