Running Monte Carlo (and other software from PBI) from a hard disk.
|
||
|
|
|
||
|
|
The problem: Too many CDA's or NDA's loaded cause Monte Carlo to fail
|
||
|
|
with a "Memory allocation error" when launched from a hard disk.
|
||
|
|
|
||
|
|
The reason: Poor memory management by PBI (Or perhaps a poor method of
|
||
|
|
attempting to do Copy Protection). Anyway, PBI tries to allocate a specific
|
||
|
|
storage location that may not be available if CDA's or NDA's have been
|
||
|
|
loaded.
|
||
|
|
|
||
|
|
The solution (At least one anyway):
|
||
|
|
Two small programs to execute at boot-up time to reserve the memory that PBI
|
||
|
|
wants later on. One program reserves the memory before any CDA or NDA
|
||
|
|
loading takes place, the other releases the memory after loading has been
|
||
|
|
completed.
|
||
|
|
|
||
|
|
REQUIREMENTS: You MUST be booting into Prosel's START program in order for
|
||
|
|
all this to work correctly and automatically. I have been using this
|
||
|
|
set-up for a while and have seen no problems so far.
|
||
|
|
|
||
|
|
The set-up: There are two programs included in this download.
|
||
|
|
|
||
|
|
MEM.SAVE is a File Type $B6 file. This type of program is executed by
|
||
|
|
Prodos-16 at Boot time. This file MUST be copied into your
|
||
|
|
/system/system.setup directory AND MUST be moved to the TOP of the
|
||
|
|
directory! Of course, since you must be a Prosel user to use this,
|
||
|
|
you can use CAT.DOCTOR to re-sort your directory and move this file
|
||
|
|
to the TOP.
|
||
|
|
|
||
|
|
MEM.CLEAR is a File Type S16 file. I recommend that this file be copied
|
||
|
|
into the /system directory.
|
||
|
|
|
||
|
|
IMPORTANT!!!!!!!!!!!!!
|
||
|
|
|
||
|
|
The START program from Glen Bredon needs to be modified via Block Warden:
|
||
|
|
|
||
|
|
Glen has included a feature in Block warden to detect if the program being
|
||
|
|
edited supports the Prosel start-up pathname feature. See the Prosel
|
||
|
|
documentation for mote details. The program START must be modified to set
|
||
|
|
the start-up path to:
|
||
|
|
|
||
|
|
*/system/mem.clear
|
||
|
|
|
||
|
|
NOTE: If this step is NOT done then you will probably have BIG problems
|
||
|
|
since the memory has already been reserved by MEM.SAVE but NOT made
|
||
|
|
available again by MEM.CLEAR.
|
||
|
|
|
||
|
|
For the curious: The two programs were written using APW assembler and
|
||
|
|
contain tool calls to the memory manager to perform the
|
||
|
|
allocation/de-allocation functions.
|
||
|
|
|
||
|

|

|
|
(I have accumulated over $1,000,000 on the video poker machine) I will
|

|
|
accept any and all donations from the proceeds.
