Recently, a reply to a question about the HP 7906 disc drive stated that the
HP1000 did not allow new discs to be generated into the system. Both RTE-IVB and RTE-6/VM operating systems allowed the system generation to be modified.
This process required changing the operating system's answer file and then
running the generation program (RT4GN or RT6GN) to create the operating
system's executable file (like vmunix on Sun systems). Then this executable
program is SWTCH'ed in to the target disc.
Unfortunately, when doing it this way, you also have to reload any utilities
you want customarily saved to the system logical units. In the days of
RTE-IVB and RTE-6/VM, the system had to reside on a File Manager (FMGR)
configured logical unit.
I believe the best contacts for information on the HP 7906 disc drive
and how feasible it would be to install on a current system would be
