It's simple really. Begin a Solaris 8|9|10 install, make it as minimal as
hell. After the first reboot it will ask if you want to update OBP [0]. Make
sure the machine has the jumpers set to allow the flash ROM to be written
and choose yes. After the ROM gets updated just shut the machine off. [1]

Now here is the fun part. Put the drive in next machine to update OBP on. It
will boot up and ask if you want to update the ROM[0]. :)

[0] Providing the box needs the ROM updated.
[1] Don't forget to put the jumpers back in write protect mode.
