I managed to install 1.6-rel on a new HD, on a pmac 4400/200 that ran 1.5.2
before.

Everything seemed to work fine (had to try three different discs before one
booted, but that is normal for OF), but after installing, on the first
reboot, the bootloader hangs.

It starts loading the first block of data, shows the twirly; but after a
while the twirly stops, and the machine hangs.

Anybody any idea's ? I have not the faintest idea.
