	Barry,

	  My previous reply should allow you to build a new file system
	on the rz0h partition which you should then be able to mount.

	As for being able to boot Ultrix, you don't mention which system
	you are running from. The boot command you gave should work fine
	for a boot command run on a DS2100/DS3100 system booting off of
	a disk whose SCSI ID is 1.

	However, if you are booting off of a DS5000/200 (or any of the
	follow-on products coming soon to a theatre near you) the
	command string will look like this:

	>>boot 5/rz1/vmunix -a

	Where 5 is the id of the Base System SCSI TURBOchannel option (the
	one on the CPU module...it could be 0, 1 or 2 if you were using
	added SCSI host adapters), rz1 is the disk drive SCSI ID (following
	your example) and the -a variant will bring it up multi-user.

	You shouldn't have any trouble booting from alternate expansion
	boxes or toggling between operating system variants (I do it all
	the time here in my lab depending on which Third Party Hardware
	vendor has customized which disk for their particular product).

	I hope that this helps.

				Thanx,
				  AJ
