Hi all,
Thanks to all who sent me their Complete Archives(tm) of whatever
brand of PC DOS memory manager they were once using... I now have
a fair selection of Qemm, 386MAX and whatnot :)
The bad news was... it didn't work. Qemm6 would work, but make
the box unstable. MAX and Qemm7 didnt work at all, they froze
as soon as they were loaded. Not good.
At some point I also noticed the box was acting strangely when
heavy network traffic ocurred, *and* that it never showed me the
Adaptec's BIOS banner.
So... I decided to swap the (DOS) disk into another PC, and try
again. Lo and behold... it works. Both Qemm7 and MAX work, and
the network card behaves, AND the Adaptec lives :) Looks like I
had a sick PC to work with...
Said PC is now running DOS 6.22 with the memory manager, MS LANMAN
client (using NDIS 2.0 driver and packet driver stub), with a full
(licensed) copy of Ersatz-11 on top of that, emulating:
- PDP-11/83, 4MB RAM
- RQDX3 disk controller
- 2x RD54 (160MB) disk
- 1x RX50 diskette (emulated to 5.25" HD disk drive)
- 1x RX33 diskette (emulated to same)
- 1x TQK50 controller with TK50 drive, emulated to TZ30 drive on
the Adaptec 1542CP.
- 1x TSV05 tape drive, emuated to HP 7980S drive on Adaptec.
- 1x DELQA ethernet controller, emulated to E100B through packet
driver on top of NDIS stub (yay! ;-)
- 1x DZV11 4-port async contr emulated by AST FourPort/XM ISA
controller which I re-found in a box of crap ;-)
The "machine" is now happily installing Ultrix-11 V3.2 from tape.
Real tape, even. Yaaaay!
Soon to be online as eagle.pdp11.nl.
Cheers, and thanks to all who helped,
Fred
