Mount: can't find /mnt/cdrom in /etc/ fstab or /etc/mtab
That means that cdrom isn't in fstab file, so you can mount the cdrom only from terminal and you have to be root.
try in terminal:
Code Sample
sudo su mount /dev/cdrom /mnt/cdrom
Another possibility is that the CDROM-drive is SATA-CDROM, and there is no way to mount SATA devices in DSL2.3 (in 2.1 it is possible)I have the same issue with a frugal install. I used to use dsl bootfrom=/hdaX/DSL23.iso (renamed the iso file) so I could use my CDROM but I got tired of needing the CD in to boot from all of the time, so after my GRUB frugal install, I get an error reading after it tries to install my DSL apps from the CDROM (why, I don't know, as I never suggested it look for them there) The error is: sr0 CDROM (IOCTL) ILLEGAL REQUEST. This pops up a few times and then DSL is up and running; however, with no CDROM access or ability to mount it with a variety of "methods" Secondly, unlike my failed LILO install which disabled my ability to get into Windows, the GRUB setup menu did not ask where I kept my DSL Apps. But I can get into Windows because it asked me that key question. I just load the APPS manually as I need them... I am running a 200 MMX laptop with 96 MEG, so I am fairly limited and loading extra apps anyway. Help with the CD would be nice, if there was some simple way of doing this. I like LINUX, yet somewhat hate it due to its DOS like complexity of commands. Yes, I was around for DOS and Win 3.1. Still, LINUX is fast, and it handles memory well and the people who use it are such a great community to "hang out" with on these boards.
