[Voyage-linux] Alix 3d2 rescue system

[Ernesto Sanchez]

Now i've this grub menu.lst:

serial --speed=38400
terminal serial

timeout 15
fallback 1
default 0

title USB restore
root (hd0,0)
kernel /boot/boot-usb/vmlinuz-2.6.38-voyage root=/dev/sda1 
console=ttyS0,38400n8
initrd /boot/boot-usb/initrd.img-2.6.38-voyage

title voyage-linux-15Apr10
root (hd0,0)
kernel /vmlinuz root=LABEL=ROOT_FS  console=ttyS0,38400n8
initrd /initrd.img

Unfortunately when you boot without the presence of the usb, starts a 
minimum shell, I think if at that point could generate a kernel panic 
would restart and grub would start the fallback.

What do you think?

But first busybox (and others?) must be instaled and initrd be updated. Busybox is a little to big to include in tarball (Punky?).

Unfortunately TinyBIOS not support booting from USB devices, so I'm trying to do it from the grub installed on compact flash, I thought it could use the fallback option of grub ever tried making usb boot first and then the compact flash the problem is that grub does not detect the usb-stick.
