You could also add a /boot partition at the front of the drive (within the
1024 cylinder boundary).  The /boot partition only needs to be 16MB max if
you use lilo - much larger if you use grub.

I had a similar problem upon installation of RH7.1.  My /boot partition
was past the 1024 cylinder boundary and I kept getting the dreaded sig11
error and could not install.  The sig11 error is supposed to be an
indication of memory, processor, or mobo hardware faults.
