[G4] Dual 1.25 MDD G4 won't boot OS X. Any ideas?

[Eric Wood]

It seems as though that particular installation of OS X has an issue?  
Did you try a fresh OS X installation? I say zap the PRAM, and if  
that doesn't work, boot the system in single-user (is it still  
command-s in Leopard?) and run fsck -y to look for problems on the  
drive. And try a fresh installation if you haven't yet.

My Mac stopped booting Linux, strangely enough, and I've never found  
a solution to that one.
