I've been trying to add a second TK50 to my system. What I'm planning
is really to add a 3rd party digital video tape drives to my system
(uVax II/GPX, Ultrix 2.0), but until I have that hardware, I decided
to test the configuration with a second TK. The problem is, I can't
seem to get it right. The controller (TK or digital video tape) looks
like a TMSCP device, but I don't know how to configure it into the
system. There seems to be zero documentation on this question.
Question: How do you add a second TMSCP device?
I tried the following configs (standard lines deleted):
adapter klesiu0 at uba0
controller tmscp0 at klesiu0 csr 0174500 vector tmscpintr
tape tms0 at tmscp0 drive 0
adapter klesiu1 at uba0
controller tmscp1 at klesiu1 csr 0160404 vector tmscpintr
tape tms1 at tmscp1 drive 1
and a variation:
adapter klesiu0 at uba0
controller tmscp0 at klesiu0 csr 0174500 vector tmscpintr
tape tms0 at tmscp0 drive 0
controller tmscp1 at klesiu0 csr 0160404 vector tmscpintr
tape tms1 at tmscp1 drive 1
These kernels both seem to compile correctly, and to configure
correctly at boot probe time. I then made and tried various devices
(tms1, tms4, tms5). Opening the tms[45] devices simply fails, saying
the device is nonexistent. Opening the tms1 device causes a machine
panic (except once, when it read the tms0 device!).
HELP!
