Re: Debian on Power 740: yaboot can't open device
Try to edit /etc/yaboot.conf with a live CD in this way
##
boot="/dev/disk/by-id/scsi-SAIX_VDASD_000636ea0000d70000000131d841f07d.2-par
$
boot="/dev/sda2"
## device=/vdevice/v-scsi@30000004/@1
## partition=2
root="UUID=d4aa39cf-a3ff-47a0-8621-e22eee3e1575"
timeout=50
install=/usr/lib/yaboot/yaboot
enablecdboot
Comment the default line boot, and add the boot with the /dev partition
where the system is install. This works for me.

The only aspect where my install differs is with regard to the use of
multipath. I use a plain old scsi disk and only have one VIOS in the
machine.
