Hi Stevo,

Did you make your SFS partition with MOS on it bootable?
The FFS partition mustn't be bootable.

Next step:

If you are in the firmware, type: show-devs and Enter.

See in the list if you see something like "/pci800000/ide70000/disk@0,0 (block)"

Don't mind the numbers, only the "disk@0,0" part is important.

If you see this device try then booting from it with the command:

boot_/disk@0,0:0_boot.img

The underscore is a space!

Let's now if it works

Good luck,

Spidey
