Hi,

I made a few patches to boot. The following problems are fixed:

* You can now boot from sdX:/netbsd (where X is > 1)

* You can now boot a kernel with a zero size symbol table.
  (this is usefull for boot floppies. You can get a working system
   including the kernel on a 1.44 mb disk)

* Most important: We finally got a running wheel like the sun :-)

* I think scsi_low.c should not reset the scsi bus (one of my disks
  gives me problems if scsi_low resets the bus).

	Matthias
