- The SUPRBDOS program as modified by Benjamin Ho has always looked
- interesting to me, but I've never been able to get it to work on
- my system. I've finally succeeded, and perhaps my experiences
- will be able to help someone else.
-
-
- NOTES: 1. On the Northstar Advantage, the SYSGEN does not
- take a file as an argument, so standard Kaypro installation
- can't be used. Manual installation is required with some
- minor modifications.
- 2. On the Northstar Advantage, the <BdosMemAddr> is DF00.
- The SYSGEN image is at 1D00. The offset thus is 3E00.
- Most users should be able to find their corresponding
- addresses using the guide found in SUPRDOS2.LBR.
-
-
- SYMPTOMS of the original installation which didn't work:
- 1. All CCP functions worked fine (DIR, TYPE, ERA, SAVE, USER)
- including functions that took a file as an argument.
- 2. Any attempt at running a file from disk (STAT, PIP, etc)
- fell into a black hole.
-
-
- The MODIFICATIONS that finally did the trick:
- 1. Modify the range of bdos that gets filled with zeroes.
- WAS: f <BdosFileAddr> <BdosFileAddr+$0E00> 0
- IS: f <BdosFileAddr> <BdosFileAddr+$0E00-1> 0
- 2. Carefully note the serial number and patch back in after
- having overlayed the SYSGEN image with DOS.HEX.
-
-
- The final steps in their exact sequence were:
- 1. Create a one line ORG.DAT. Specifically: org 0df00h
- 2. Create the file DOS.HEX using Z80MR on DOS.AZM & DOS?.MAC
- 3. A>sysgen
- SOURCE DRIVE NAME (OR RETURN TO SKIP): 1
- DESTINATION DRIVE NAME (RETURN TO REBOOT): <ret>
- 4. A>ddt (original DDT only, *not* DDTZ)
- -f1D00 2AFF 0 (note! 2AFF not 2B00)
- -iDOS.HEX (per the original instructions)
- -r3E00 (per the original instructions)
- -s1D00 (note! repatch the serial # back in)
- 00 01
- 00 02
- 00 03 etc, etc, etc
- -^C (exit DDT)
- 5. A>sysgen
- SOURCE DRIVE NAME (OR RETURN TO SKIP): <ret>
- DESTINATION DRIVE NAME (RETURN TO REBOOT): 1
