RT11 dual mscp problem

[Roe]

I have an 11/83 in a BA123 with two MSCP controllers, a CQD220A at 172150 and an RQDX3 at 160334. The rqdx3 has an Rx33 floppy drive, and is set for starting LUN 4.

Unix has no problem with this setup, and sees the floppy as /dev/rra12a.

RT11 does not see the floppy. According to the docs, I should run

.SET DU: CSR2=160334

To set up the second controller. That set command returns a syntax error.

This is RT11 v5.7.

Anyone have any ideas?

I'm pretty sure that you will need to regen your version of RT-11 to include two MSCP devices; I think the default is one. Check the docs to be sure.

Thanks. I'm going to run a full sysgen now, let's see how it goes.
