My dma was off I had to change hdparm.conf and it seams to work fine now.

I agree I don't think the problem is the HD but here is what I get on an
Athlon 700.
root@rebel:/# hdparm -Tt /dev/hdb
/dev/hdb:
Timing buffer-cache reads: 596 MB in 2.01 seconds = 296.52 MB/sec
Timing buffered disk reads: 34 MB in 3.11 seconds = 10.93 MB/sec

Well after installing the OS for like 7 times I figured I get it first to run
before I make any changes, because if I can't get this going I will have to
go back to win2000 on this box, which I don't want to do.

I compared Floating-Point Unit output to my other AMD box and it seams to be
OK. I have added the boot.message at the bottom maybe you can see something
else.
