Is it possible to put more than one partition on the
to convince RT-11 to use more than 32mb of the disk?
RT-11 uses, IIRC, 16-bit
block pointers... 65536 x 512 bytes == 32MB,
the largest swath of a big drive it can grab in one chunk. I've
personally run RT-11 with a disk over 32MB, so I don't know how it's
done, but I know it can be done. It might or might not depend on
version of RT-11 you have. I *think* if you have MSCP support, you
always have the ability to have multiple partitions on your large
drives, but someone with experience on new(ish) hardware should chime
in. The largest machine I ever ran at home was an 11/23 with a
of RL drives. When I did use RT-11 on an 11/73 with a large disk, it
was under TSX-11, and without the docs in front of me, I'd
quote technique from memory.
You should be able to find what you are looking for in the RT-11 docs
for versions of RT-11 > 5.4, at least. Dunno about < 5.4.
It is possible... I use an Emulex SCSI controller on my 11/23+ and
it works with multiple partition support via MSCP.
Each DU: driver can control several partitions (7?). It has to be
configured... Don't know how I did it. But I *think* there was
something about a "set" command.
