I just put a snapshot of the i386 boot code to
ftp://zelof1.zel.kfa-juelich.de:/pub/NetBSD-booter/bootcode-250895.tar.gz

I got unexpected problems with loading from DOS devices (via int21).
It works on some hardware, on some not (for me, SCSI disks on PCI/NCR
don't work, floppy is ok). I remember a patch for the NetBSD bootblocks from
somebody in norway which added support for DOS devices. Can anybody point
me to this guy or give hints how to fix the problem?

best regards
Matthias
