ubuntu 8.10 unable to detect cd rom

Asked by izzy200198 on 2008-11-09

i have a computer with two SATA drives and one IDE cd rom drive. I installed ubuntu 8.04 back in April and have been running it all this time no problem. I upgraded via internet to 8.10 and noticed after reboot that my cd rom drive was missing. Booted from previous kernal in grub menu and it was there again. But with latest kernal its gone. Decided to start over with the 8.10 alternate cd and installation stopped at unable to detect cd rom drive. I am completely frustrated at this point and am out of ideas.

I dont know why 8.10 cannot detect my cd rom drive when 8.04 had no problem at all. I thought 8.10 was supposed to have "better" hardware support. But in my case upgrading to 8.10 resulted in Ubuntu no longer being able to detect my existing hardware from 8.04. Can anyone help me with this?

I need more information.

Upgrade to 8.10 and after reboot, attach the output of (Application>Accessories>Terminal):

$ lsmod | grep sd_mod

$ lsmod | grep ata_piix

thanks!

Found the problem. I changed the jumper on my lite-on cd/dvd rom from slave to cable select. the cd rom was alone on its own ide cable. for whatever reason, 8.04 didnt seem to care. but 8.10 wants cable select in order to detect the cd rom.
