Well, the matter is simple: I'm trying to install 2.11 BSD in one PDP-11/23
PLUS with 4MB of ram, and the 'restor' and 'icheck' utilities
don't load in
he PDP, returning this message:
"Can't load split I&D files"
I tried with the diverse distributions of Vtserver and diverse versions of
'restor'. In the case of the 2.9BSD this don't happen but the utility
can't
understand what is the 'vt' device.
Someone has encountered and solved this problem ?
Regards
Sergio

I could be wrong, but I think the 11/23 is not a split ID CPU?

That's correct. The 11/23 supported 256K memory and separate Kernel and User but not
separate
I&D.
An 11/73 does support separate I&D...

11/83, 11/84, 11/94.
I think the 11/40 and the 11/34 didn't have it. I don't think the
11/60 did either.
The 11/03, 11/23 and 11/23 plus and 11/24 didn't.

Correct, it isn't. You cannot run 2.11BSD in a PDP-11/23 or similar
machine because a lot of things in 2.11BSD require split I&D. It's
declared on the first page of the setup instructions:
"This distribution can be booted on a PDP-11 with 1Mb of memory or
more, separate I&D, and with any of the following disks:"
You need an 11/73 or better to have split I&D. For those who might not
know what that means, it refers to the processor's ability to keep
I(nstructions) and D(ata) in separate spaces, so in effect virtually
doubling the amount of memory that can be used. That is, you can have
(almost) 64K of instructions *and* (almost) 64K of data at the same
time. Without split I&D, you have 64K in total for both.

As Pete says, you can't run 2.11 on an 11/23.
However, I do run 2.9 BSD on my 11/34 as it does NOT require seperate I&D
as does 2.11 BSD.
Might want to try using 2.9 on your 11/23. Here's the CPUs supported by
2.9 BSD:
11/23, 11/24, 11/34, 11/34A, 11/34C, 11/40, 11/44, 11/45, 11/55, 11/70
Min. required memory is 192K
