I always though that the maximum was about 32 devices,
so I guess I will need to check.
... in Bstrap.mac:
90$: CMP R3,#<HNAMES+<40.*4>> ;More than 40. handlers here?
BHIS 110$ ;Yes, can't remember any more
Also, although the system device is LOADed at boot
time,
the SHOW DEVICE command shows "Resident" as the actual
status - which I agree means that it can't be UNLOADed.
Yes, 'Resident' is determined when the handler base address
is above the base of RMON.
Finally, as discussed elsewhere, even normal
"properly
written programs" can't .Fetch a device driver if it is
being run as a "system" or "foreground" job.
I'll have to check on this... my RTEFTP program may be
using tricks to accomplish it. I know it does it when
running virtual or under VBGEXE (with the /BUFF:n option
for SRUN or FRUN)
