So far I’ve been trying ‘vax412’ with the various images at DKA0 and DKA100
(the two drives listed when you do a “SHOW BOOT” from the ROM prompt. At this
point I fear a sample .ini file may help. :-)
Looking at the strings at the beginning of each disk, I’m starting to wonder if
any are actually bootable. I see that a couple say "is not a system disk”, and
the rest say “IS_KEY_DISK”, so I’m wondering if any are bootable, even though
it seems like I should be using InfoServer/VMS V3.5 (ag-r7lfa-bs.img), which
says, "IS_V35 is not a system disk”.
