What is an HP98616?

I just looked at the BASIC 5.1 Installation Manual and it doesn't say but when I look at the list of BIN driver files I see HP-IB, DISK, HP9885, CS80 and others. It says HP-IB is required in order to use the HP-IB, DISK provides support for "non CS80 disk drives such as the HP 82901 and the HP 9121", HP9885 provides support for the HP 9885 drive, CS-80 provides support for the CS-80 type disk AND SS-80 type disk. CS-80 also requires installation of the HPIB BIN file. Since they provide these BIN files I have to think that the BootROM does not support them. OTOH the drawings show them cold booting what looks like a HP 9000/300 from an external drive so maybe it is possible. The manual doesn't say a word about what external devices are supported and what aren't prior to loading the BIN files. I've only had completely built OS systems to play with up until lately so I have little experience with minimal OS and builting the OS systems. (the 9836 has 2 interal drives, but they are 5.25" ones, of course). It should. I have a 9123 with an external PSU on a HP 150 and it works exactly like a 9122 as far as I can tell. Joe PS the command to save a built OS file is STORE SYSTEM filename and not SAVE SYSTEM.
