If it is a dual head graphic card try to connect the monitor to the
other connector.
There may be a phantom TV port on this card (with no actual TV connector
on it) which gets chosen as the output. You can disable the TV part by
passing video=TV-1:d or video=TV-2:d to kernel. You can add these
options to "append" field in yaboot.conf
Example:
image=/boot/vmlinux
label=Linux
read-only
initrd=/boot/initrd.img
append="video=TV-1:d"
Boot the machine using install DVD. On boot prompt type:
rescue64
choose the apropriate options until you get the "Enter rescue mode"
screen, then chose your root partition and choose to execute shell in
the root filesystem.
You will have the familiar command line environment.
You can edit yaboot.conf using vi or nano to add wanted options to
"append" field.
You can install openssh-server with intention to log into the machine
using ssh after reboot.
Type exit, and choose reboot.
