[comp.sys.sgi] help needed installing 1553 memory board

rashkin@ELXSI.DFRF.NASA.GOV (06/07/90)

Any help would be appreciated.
 
We are installing a VME 1553 memory card into a 4D/80GT.  Specifically,
an ILC DDC Bus-65522/23.  Supposedly, I can alter /usr/sysgen/master.d/mem
to include memory partitions.  According to /usr/sysgen/system address
space bd100000 is reserved for customer boards.  I have had zero luck
with a program trying to use mmap to this address space.  I reverted
to trying to get the prom monitor to work.  I'm trying put and get, but
the monitor bombs off at all address combinations I have tried.  Any
experience in this area would be really helpful.
 
Thank you,
