Hello.

I'm making a dvd MultiDistro and I am modify the syslinux for backtrack:

PROMPT 0
DEFAULT / bootT/vesamenu.c32
TIMEOUT 40

LABEL BT4
MENU LABEL BackTrack Start FrameBuffer (1024x768)
KERNEL / bootT / vmlinuz
APPEND vga = 0x317 initrd = / bootT / initrd.gz ramdisk_size = 6666 root = / dev/ram0 rw quiet boot = casper

BT42 LABEL
MENU LABEL BackTrack Start FrameBuffer (1024x768)
KERNEL / bootT / vmlinuz
APPEND vga = 0x317 initrd = / boot bootT/initrd2.gz ramdisk_size = 6666 = casper root = / dev/ram0 rw quiet

BT43 LABEL
MENU LABEL BackTrack Start FrameBuffer (1024x768)
KERNEL / bootT / vmlinuz
APPEND vga = 0x317 initrd = / bootT / initrd.gz boot = casper boot = casper nopersistent rw quiet vga = 0x317

I get a kernel error.
-Kernel panic - not syncing: VFGS: Unable mount root fs on unknown-block (1,0)
