I to have an emac 1.25 7447? with the same issue as Alex McKeever
I tried replying to the tread but when I hit reply it seemed to just
delete my post. You will no doubt receive another 2 versions of this
I try and answer the same questions you posed Alex
Is this the 1.25 GHz retail model (Radeon 9200) or the 1.25 GHz education
market model (Radeon 9600)?
I think it's a 9200
Are you able to see the GRUB menu?

Are you using Mini-VGA or the built in display?

Yes after running the adelie ppc full CD and getting the blank screen. :-(
I have a freebsd install on the machine and it boots (or booted) from
open-firmware. When I booted adelie by holding the c key freebsd started
open-firmware. The CD booted and I got a blank screen mid boot but it has

open-firmware but got nothing so I press the pmu and rebooted with the
open-firmware keys I got open-firmware then the sad-mac icon and then
freebsd started. It then rebooted it's self and reverted to the black
screen and I can't seem to revive open-firmware again (yet). I hope it's
not bricked :-(
