[Fedora-livecd-list] Good download and burn but unsuccessful boot

Hi All, I downloaded the FC 6 live CD ISO from the official Red Hat download directory and verified the sha1sum. Then I burned the ISO to a CD using cdrecord, which had no complaints about the burn. However when I boot from this CD, the boot process gets through uncompressing the kernel then says something to the effect that /dev/root does not exist, I need to create a symlink and it drops me into a shell. And sure enough, /dev/root does not exist. The hardware is a pretty plain vanilla old Pentium with half a gig of ram, parallel IDE and a couple of Adaptec SCSI cards, and the Pioneer DVD burner that the CD is booted from (which is connected as IDE secondary master). I've never had a problem booting Knoppix 5 on this machine. Fedora Core 6 boots from the IDE primary master hard drive with only one complaint, something about incorrect PBLK length [5] on ACPI(?), but then goes on to boot and run successfully. When run from the hard drive, FC 6 /dev/root is a character special device not a symlink. Whazzup? Thanks in advance -- Walt
