S1= ON Boot to ODT 165xxx
S1=off Boot selected device 173xxx
s2=off for 11/24 use
s3 through s10 are starting add.

Try 173004g


or R0/ x Where X is the device # you want to boot from (0,1 etc. depending
on what unit has the system pack in.)
Then 173012g it will size memory as above then boot selected unit.

I am surprised you have the M9312 in that machine since you have 1 meg of
memory. Normally you would put the boot rom on the KT24 (M7134) and use
just a M9302 terminator.

I think I have a second 11/24 system technical manual around here but I
can't find it at the moment. I will keep my eyes open for it in the
meantime. It is to thick to readily copy and I use it to often supporting
several customers that are still running them in production to loan my only
copy.
