Chainload in libreboot?

ordealbyfire83 · 02-07-2016, 09:59 PM

I must admit I am no expert with grub2. I would like to chainload to a partition which has grub(1) (aka "grub-legacy"). Yes, I know I could just boot it up with grub2 but it seems like something is amiss. The partition is a primary partition, number 4.

So far I am trying

Code:

insmod ahci
insmod ext2
insmod part_msdos
insmod chain

chainloader (ahci0,4)+1

and get "error: unrecognised payload type". I have seen another tutorial that calls for a command called "drivemap" but libreboot does not apparently have this. Any suggestions?

at the grub prompt what is the output of ls?

grub> ls
(memdisk) (proc) (cbfsdisk) (ahci0) (ahci0,msdos4) (ahci1)

where ahci0 is the internal hard drive and ahci1 is the dvd drive (currently holding a live cd). Writing chainloader (ahci0,msdos4)+1 doesn't do anything different.

when the disk was first partitioned it was set up as a msdos partition table and not a guid partition table?
