When booting from srm prompt with the following line
  b dka400 -fi kernels/generic.gz -fl "root=/dev/scd0"

The system panics almost imeadiately after aboot finishes
loading and the kernel starts.  This has been reproduced on
several similar systems with 300 and 400 mhz cpu's.  If the
mikasa-s-5.gz kernel from the redhat 5.2 cd is used instead
of the 6.0 generic kernel, you can get the system
installed.  However if you do this the setup program cannot
configure the system after loading all the rpms.

This platform is on the supported list, I would think that
it would at least boot.
