CP/M-68K (tm) Operating System Release Notes
|
|
|
|
February 17, 1983
|
|
|
|
|
|
S-RECORD SYSTEMS
|
|
|
|
Either of the two S-record versions of CP/M-68K included in
|
|
|
|
this release may be combined with a user-supplied BIOS in order
|
|
|
|
to obtain a working CP/M-68K operating system as discussed in the
|
|
|
|
System Guide. In addition to the information given there, you
|
|
|
|
need to know the size and entry points of the S-record systems.
|
|
|
|
The two S-record system files are discussed separately in the
|
|
|
|
following paragraphs.
|
|
|
|
SR400.SYS resides in memory locations 400H to 5D43H. You
|
|
|
|
should patch it by placing the 32-bit address of your BIOS's
|
|
|
|
_init entry point at memory locations 4F42H to 4F45H. Your BIOS
|
|
|
|
can Warm Boot by jumping to 4F46H.
|
|
|
|
SR128K.SYS resides in memory locations 15000H to 1A943H.
|
|
|
|
You should patch it by placing the 32-bit address of your BIOS's
|
|
|
|
_init entry point at memory locations 19B42H to 19B45H. Your
|
|
|
|
BIOS can Warm Boot by jumping to 19B46H.

BUGS
|
|
|
|
o The CPM.SYS file on disk 2 of the distribution system was
|
|
|
|
intended to work with a floppy disk EXORmacs(tm) system. In
|
|
fact, it does not.
|
|
|
|
o AS68 will not operate properly when the disk it is using is
|
|
full.
|
|
|
|
o If you have trouble with AS68, it is likely that you did
|
|
|
|
not initialize it. See the Programmer's Guide for
|
|
|
|
more information.
|
|
|
|
o DDT sets up an incorrect command tail when the program under
|
|
test is specified on the CCP command line invoking DDT rather
|
|
than using the E and I commands in DDT.
