have once move one HD to another mobo and it worked fine,
was so impressed by Linux :-), but this was a modern mandriva distro
which run hardrake (material detection) and this was
from a PIII to a PIV if I remember ok.
Anyway this is luck of the draw
and the computer would re-boot every time it tried to load a graphical environment.
Sounds bad, should not reboot. Is the mobo ok?
You can try kernel parameter video=vesa
FC6 is out, maybe you could try Fc5, not fc4, do not know
>>Well I tried to upgrade to Fedora Core 4
Upgrade or resinstall fully?
I doubt an upgrade would work very well, but at least some
of the settings would not be lost
I hope you made a backup at least of /etc if you have settings in there
and I assume /home is on a different partition
if fc4 cd boots there must be a rescue mode to get to a command line
mode to at least backup /etc (hint cp -R)
