Running Paintworks Gold from a Hard Disk

[twyant@freenet.vcu.edu]

Thanks to all who responded; most of the following comes from
correspondance with John P. and Leif Strand. My apologies to
them if I have mangled their information. 

The problem originally posted was "Running Paintworks Gold on a
hard disk," or some variant on that theme. It turns out that
apparantly the problem is not putting it on a hard disk per se,
but changing versions of the O.S. (which you must to to get to
the hard disk). The specific symptom is that PWG displays the
splash screen and then crashes. 

Apparantly Paintworks Gold (V1.5) calls on the operating system
for a goodly chunk of memory, requesting it at a fixed location
which is never available in any modern version of GS/OS. This
problem was diagnosed by Jason Harper, and a patch published on
AOL (back when they spoke to A2 types). The patch involves
looking in the program for the string of hex bytes C9 08 00 D0
CE 00 4C, and changing the second byte from 08 to 7F. This
string appears only once. This apparantly causes the memory
allocation request to ask for memory wherever it can be found,
and allows it to succeed. Although PWG claims to run in 1.25 meg
(and will as distributed), Jason recommended at least 1.5 meg to
run from a hard disk, to allow for SCSI driver and expansion of
GS/OS. 

Just to close things out; my PWG no longer crashes as soon as it
displays the splash screen; instead it crashes about 15 seconds
later. I suspect that the problem now is that I haven't got that
extra 256K. Even 5.0.4 without the finder (using MicroWings
instead) does not cut it. Guess I'll have to fork out for that
memory expansion after all. 

Thanks to everyone for the help!
