Hi, Freebsd-questions.

I try to make up my own LiveCD
mkisofs -V FreeBSD -RJ -iso-level 3 -no-emul-boot -o bootcd.iso relesase

I copy bootcd.iso to flash and install grub to flash.
then boot from flash
in GRUB:
map (hd0,0)/iso/bootcd.iso (hd32)
map --hook
chainloader (hd32)

press key
lsdev shows
that there is CD0 device.
'show' shows that currdev=cd0: and rootdev=cd0:
boot process starts system
Mounting from (...) failed with error 19

when I press '?' sign it show no CD0 device.

It seems that memory device was destroyd by 'kernel' and on this stage
'mapped by grub to memory iso file' does not exists

How can I fix it?

I do not undestand what to write to 'vsf....' variables.
