GVP040 HELP????
2 messages in this thread
Hello, GVP:
A few months ago I purchased a GVP 33MHz 040 accellerator (a "GFORCE", I think
it is called).
It was one of the 040's that had "perfect with the Video Toaster" on the box.
Well, not quite perfect so far in my case.
With 12MB memory on board I am as yet unable to run the Toaster with the
command
GVPCPUCrtl MoveSSP FASTROM
in my user-startup file. Using this causes either an immediate crash or one
within a few seconds
after starting the Toaster switcher.
The show-stopper is the FASTROM statement. With it removed, the Toaster will
run.
Among the many "suggestions" that I have received from the Toaster-heads on the
nets, was one to use
the sequence:
cpu nocache noburst nocopyback
GVPCPUCrtl MoveSSP FASTROM
cpu cache burst copyback
arp040fix
in the user- startup file.
The message also stated that unless I had FULLY populated the board with
memory,
FASTROM, burst, copyback, etc, etc., would NOT work…
PLEASE, PLEASE tell me what is the straight story here???
Arrrghhhhhhh!!!

Luke,
The CPU lines are correct. Some A2000 motherboard will experience
timing problems when remapping the Kickstart ROM with the caches on.
I'm not sure what the ARP040FIX line is all about. As for being
FULLY POPULATED, the BOARD will only support BURST mode when fully
populated. Your caches will always work and turning on burst in
SOFTWARE without the board being fully populated will make no
difference. Hope this clears things up.
