The old PROM's have odd syntax.  The syntax is :

	b type(controller, device, partition)

where :

	type is 'st', 'sd' (or 'cd' on newer PROM's).

	device is the (hex) value of the SCSI ID multiplied by 8
	(e.g. id 1 = 8, id 2 = 10).

	partition is the partition (or file number on tape) [*]

	All values start at 0.

So, if your tape is id 4, you will need :

	b st(0,20,0) -s

PS.  Could this go in the sun3/sun3x/sparc boot.8 man pages?  Should I submit
a PR?

[*] I think only cartridge tapes are supported for booting.
