Different CHS translations?  Can you supply us with the disk
geometry of the drive you installed, as it was detected by the
host machine?

Uh, Athlon != K6.  Athlon is the successor to K6.

Compile for Pentium or K6 architecture.  Do not use instructions
introduced in PII/PIII/P4/Athlon, such as CMOVxx.  If you stick
with "-march=pentium" or "-march=k6" or earlier, you'll be fine.

Until IDE drivers are loaded, one is confined to the first 1024
cylinders.  Having a kernel in ROM helps. ;-)

Hmmmm.  "Unable to mount root fs on 03:01", which is /dev/hda1.
