Remember that with grub, the partition numbers start at 0, *not* 1.  So 0, 0 
is sda1 and 0,1 would be sda2 -- which is your extended partition.  But that 
should really only matter for a {fully-manual} Gentoo installation.  Debian 
and Ubuntu have a more automated installer.

Are you sure you don't have anything like hardware virus protection enabled in 
the BIOS that is stopping you writing to the MBR?

It looks like you have three 80GB drives in RAID-0 to give you a 240GB logical 
drive.  It's also just on the very bounds of conceivability that the one on 
which the MBR is living could be faulty.  If you don't mind losing 
everything, try swapping the drives around and reinstalling.

What's wrong with lilo anyway?
