I've corrected all of the problems I'm aware of with SYS_INST and
SYS_UBOOT.  This includes the `total sectors not set in disklabel' and the
transmit errors that made loading the miniroot difficult on a busy
network.  They can be found in the usual location:

ftp://ftp.netbsd.org/pub/NetBSD/NetBSD-1.3_BETA/hp300/installation/misc/

I'll be off for the weekend in a moment or two, but I plan to check in
periodically if I can.  Let me know if there are any problems, please!
