Excellent! That worked great. Do I also need
DU.SYS or can I get
rid of that?
You would need the 'X' (extended) versions of device drivers any
time you are booting an extended monitor. For the single job or
baseline monitors you don't need the extended versions of device
Thanks again! I have now successfully installed a minimal RT-11 on
the RD54 of my PDP-11/73 system and it boots! Now I just have to
configure it with the programs I need (like DECUS C).
I guess RT-11 uses 512 byte blocks. My RD54 says it holds around 64k
blocks. That's about 32mb. What happened to the rest of the 150mb
RD54? Is it possible to put more than one partition on the drive or
to convince RT-11 to use more than 32mb of the disk?
