Pheonix BIOS 4.0 Release 6.0
Intel SE440BX-2 motherboard.

The disk image is 4.3 GB.

I am not sure how to create a sort table, but I'll google around and see
if I can get it going.  I just rebuilt the DVD, and the only thing that
I changed was the isolinux.bin file.  I used isolinux-1.75 from RHL 8.0,
and it worked as expected.  Is there anything else that I can do to
debug this?

Thanks,
