I buy a new 6.1 Redhat Linux to upgrade my 5.2. When I install the installer doesn't recognize my CDROM, IDE Acer model 624A. I try to select all the CDROMs on the list but it doesn't work. I try to get around by using my daughter CDROM, old Sony CDROM (realy slow, may be 1x) to install; No problem but slow. When I put my CDROM back and reboot machine, system doesn't see my CDROM. I have no problem with version 5.1 and 5.2. Hope some body will fix the problem real soon.
If this is indeed an IDE cdrom, then I cannot imagine why the installer and a running system would not be able to see the drive. Is your BIOS seeing the drive on boot-up? The only time that you should have to load special modules for a cdrom are when the cdrom is on a SCSI adapter or when the cdrom is a propriatery drive and therefore needs special drivers. I know of no IDE cdroms which do not work automatically under linux, just as adding a new hard drive. Confirm that you are able to see the drive in your BIOS setup. I will poke around here in the lab and see if we have an Acer drive that we can try out in the lab and see if we can replicate the problems you are seeing.
Closing bug due to lack of activity.
