Henry's host number here is 24. Note that you must supply the hostnumber

A.3.3. Booting from Tape
The Sun Workstation can be booted from industry-standard nine-track magnetic tape, from
a 1/4-inch cartridge tape controlled by a Sun 1/4-inch tape controller, or from a 1/4-inch
tape controlled by a SCSI tape controller, using the following command:

is a small number indicating the nth standard magnetic tape controller in the
system, or is the Multibus address of the controller.
specifies which tape drive on the controller is to be used.
specifies which file of the tape is to be booted. By convention, boot com-
mands number the first file on the tape file #0, the second #1, and so on.
The monitor ignores the supplied value of filenum and can only boot the first file on a tape.
To boot a file further down the tape, use the monitor to boot the "boot" program. Sun-
supplied
UNIX
distribution tapes always have the "boot" program on the first file of the
tape.
