Problems Booting RSX-11M V4.4 on a PDP-11/24 from an RA80 Disk Drive

Christopher,

don't you need to explicitly specify decimal notation by including a dot
after the file size? I just dug out the papers, and in my SYSGEN, it was

        PIP DU0:RSX11M.SYS/NV/CO/BL:498.=RSX11M.TSK

(OK, I have less memory than you, but this was a PDP-11/34A, and it
doesn't take any more, right?)

So for your memory size, I think you should say

        PIP DU0:RSX11M.SYS/NV/CO/BL:2050.=RSX11M.TSK

Otherwise, you may only get a system image of (octal) 2050=1064.
(decimal) blocks, and when you run VMR, you probably overwrite something
you'd better leave intact for your next boot. Alternatively, you may
during boot sniff something from behind the image which isn't healthy
for your executive.

Good luck!
Andreas
