#GVP A2000 Impact 8/X brd
2 messages in this thread
Can anyone help me? I just acquired a GVP IMPACT A2000-8X SCSI/RAM Controller
board. It has 8 megs of ram installed, but I can't seem to access the memory.
🙁 I double checked the jumpers. The install procedure described in the
manual just doesn't work.
My users guide (c 1990, page 21) says to type "ed s:startup-sequence" at the
"1" prompt. OK so far, although my prompt isn't "1"…
Then it says to insert the line "c:addmem 800000 9fffff" into the file, which I
did. But when I reboot, my amiga doesn't recognize this command or the memory.
I am running workbench 2.04 on an Amiga 2500 with 2 megs of ram. Sorry if I am
not making sense…I am a DOS man trying to learn. Can anyone help me,
please!?

Danny;
It sounds like you picked up a "rather vintage product." There should
have been a disk with the board that has the "addmen" program (probably in
a directory called "c").
That program has to actually be in "C:" when you execute the command in a
script.
You may have a real problem here in that you are using something that (I
think) was designed before the A2500 even existed and certainly before
WorkBench 2.x was out.
If you have a hard drive, copy the addmen program to the "c" directory of
the hard drive (else copy it to "c" on your boot floppy). It still may
not work since you are probably using a processor with an MMU (Memory
Management Unit) and an advanced version of the OS.
You should initially try to execute the command in "s:User-Startup"
(create the file if it does not already exist) rather than modify
"s:Startup-Sequence."
Though the general rule is to never change your "s:Startup-Sequence" but
rather make all modifications to "s:User-Startup" (as of WorkBench 2.0),
you may have to play around a bit to find a place where the command will
work.
If may be necessary to find a different program to "activate" the memory.
The Amiga is designed to use what is called "Autoconfiguration" <tm>.
This system finds all add-in cards and automagically provides memory space
allocation, interrupt assignment and the like.
Unfortunately, in the early days of the Amiga, autoconfiguration was not
too well understood by many third party manufactures and was rather
expensive to implement. Also, on the Amiga 1000 there was a region of
memory that you could not autoconfig into but could add memory by
"messing" with the system's memory allocation tables directly.
Hopefully there is someone around that has "addmemed" memory to a 2500
under 2.04 that can help you. Another suggestion would be to look for
some of the older information in places like the Fred Fish disks.
