Trying to boot from either the cd or a boot floppy will give
an error of:
VFS: Cannot open root device 08:21
Kernel Panic: VFS: Unable to mount root fs on 08:21
I'm not sure if this happens on IDE-only systems, but the
system i encountered this on had an aic7xxx-type scsi
controller controlling both the CDROM and the disk.
Passing `linux mem=128M' got the install rolling.
Even a better error message would be enough to close this
This is fixed with syslinux-1.45 in the new installer.
