Hi Adam,
I've been traveling, sorry for the delay...
With the following config, I end up booting from the cdrom. If I
take away the
cdrom definition completely, I am unable to boot at all.
I can boot fine with your config, either from sda (<boot dev='hd' />) or
cdrom (<boot dev='cdrom' />).
Have you verified your seabios supports booting from ahci as Bruce
mentioned?
Thanks,
Jim
