Problem installing 6.2 on a Sparc Classic

I have installed Redhat 6.2. about 8 times now & still
get the same error when it completes then tries to
boot.

This machine worked fine with Solaris 7 & OpenBSD, I
want to use it as Linux box now but can't get it to
boot the 6.2 installation.
Any clues???

Thanks indvance...
