I've added the the line: options ROOTDEVNAME=\"cd9660:acd0c\" to my kernel and verified that acd0 is my cdrom device. I wrote over the kernel in boot.flp (taken from 4.8-RELEASE) and created an iso image using mkisofs. I then burned the cd using burncd. The CD boots the new kernel fine, but it cannot mount the root file system off of the CD. I'm thrown to a prompt at which point I can mount root off of my hard disk, but not off the CD. It returns the error: Mounting root from cd9660:acd0c Root mount failed: 6 I'm not sure what the problem is. I can mount the cd fine after booting from the hard disk. Can someone tell me what I may have done wrong? Thanks. -- Daniel Fisher
