CPMUG volume 82 - ABSTRACT.
This volume consists entirely of Steve Bogolub's North Starì
BIOS routines. They are copyrighted, but available freely forì
non-commercial use. On the disk, he includes:
NBIOS56.ASM
A BIOS for North Star MDS-AD2 double density 5.25" floppy disk
units 1 and 2 as CP/M drives A: AND B: and a Jade Double D
Rev C 8" floppy disk units 0 and 1 as CP/M drives C: and D:.
NSCOPY.ASM
This is a utility to allow the operator to copy, format, orì
validate North Star double density disks. Copying can be doneì
between any two North Star drives, and can include all tracks,ì
or just the system (0 and 1) tracks or data tracks (2 - n).
NSGEN.ASM
Provides the functions of the Digital Research standard CP/Mì
program 'SYSGEN', but for a North Star double density versionì
of CP/M.
MBIOS56.ASM
This BIOS is specialized for remote modem dialup use. Itì
incorporates elements of Dave Jaffe's BYE program. If theì
memory location "MODEM" contains a value of zero when the coldì
boot routine "init" is entered, a special set of consoleì
vectors is patched over the genned-in set to handle the PMMIì
modem instead of the normal horizon drivers. Variable baudì
rate, and other features, are supported.
SDNBIOS.ASM
BIOS containing routines to support the following hardware: ì
disk: North Star MDC-A4 single density 5.25" floppy disk unitsì
1 and 2 as CP/M drives A: and B:. Console and list routinesì
are located in a separate module loaded by the bootstrapì
routine into high memory at address USER. That value is assumedì
to be on a 1K boundary, and the user routines are restricted toì
2 pages. The BIOS is so large, MOVCPM should be run for twoì
less than the desired system size.
SDNSGEN.ASM
This program provides the functions of the Digital Researchì
standard CP/M program 'SYSGEN', but for a North Star singleì
density version of CP/M.
SDNUSER.ASM
These routines provide console and list functions for CP/M 2.2,ì
using the hardware of the martin research machine. The routinesì
are loaded into the non-contiguous 1K of high ram by theì
bootstrap routine.
SDNBOOT.ASM
This routine is read off the disk from track zero, sector fourì
by the North Star single density BOOT PROM. It is responsibleì
for reading in the BIOS and USER routines from the disk. Itì
must then call the user init routine, then jump to the BIOSì
cold boot entry point.
