GVP 040 Combo doesn't recognize SIMMs

[astuermer]

I recently bought a GVP 040 Combo for my A2000. Works perfect, except it doesn't recognize the attached 4x 4MB GVP SIMMs. I already tried each one separately with Burst Mode Off, but without success.

Do I have to activate them manually by software ?

Is the GVP 040 Combo incompatible with DCE's MiniMegi Chip ?

Any help would be nice

Do you have the Jumper (J20) closed which you need to use 4mbyte SIMMS?

You might need to close Jumper (J26) if your A2000 motherboard is revision 4.3 or earlier.

As you mentioned Burstmode can only be selected if there are SIMMS in ALL the sockets.

Here is the Manual incase you dont have it.

J20 is closed.
J22 was open before and closed now too.
J26 is open, since I've goot Rev 6 Board.

ShowConfig recognizes a 040 with FPU, my 2MB ChipRAM and all Boards, but not FastRAM. Perhaps the GVP doesn't want DCE's MiniMegi Chip ?

Kind regards

There's a GuruROM attached to the GVP Combo 040. If I disable Autoboot, I can unmount the GuruROM or?

I think it's defect.

I dont know, Ralph Babel is your man. Dont throw the Guru away. It CAN be reprogrammed.

Hmm, Ralph babel told me today that he isn't responsible for the GuruROM ?!

Anyway, I fixed several Pins on the defect ROM-Adapter, cut Pin 1 and 27 and now the GuruROM works, the RAM too

Now I've got only one problem:
When loading the PicassoII driver, the Amiga crashes with an error-message: Program failure (Error: #8000000x)... where "x" is something from 3, 4, 8 or B.

Kind regards

Amiga crashes with an error-message: Program failure (Error:#8000000x)

According to Gurus99 from Aminet that is a Hardware/ Bus Error.

The A2000 only has 8MB of Autoconfig Zorro II space. The Picasso II wants to use 2MB. That means you cannot have more than 4 MBytes on any other Zorro card that puts the RAM in the Zorro II space.

Check any other cards you have see if they use Zorro II space.

You might check your 040 card and see if it is placing any of its memory in that space (It shouldn't!).

The Picasso has a jumper on it to run in what is called "Segmented" mode. That makes the board slower but *might* allow you to work.

I DONT recommend using Segmented mode if you can get away with it. Plus I am not sure if Picasso 96 supports Segmented mode?

To change to segmented memory mode, there is a jumper next to a row of four chips, on the right hand side of the card. This should be ON to enable segmented memory.

All I can suggest over that is make sure you have the latest versions of all the software (GVP & VillageTronic) installed.

Hello,

The PicassoII is the only card, which takes 2MB of ZorroII Memory, the others only take 64K of ZorroII Mem.

The GVP 040 has extended Memory (I think it's called so).

Segmented Mode doesn't work with Picasso96 - I have already tried it, the Amiga refuses to start then.

There's already the latest software isntalled on my system.

I've really no idea what's wrong...

PS: I've got those cards in the these slots (Nr. in brackets)...
Algor PRO USB (ZII Slot 5)
Buddha IDE Flash (ZII Slot 3)
PicassoII (ZII Slot 1)
GVP 040 (Accellerator Slot)
Scandoubler/FF (Video Slot)

I now have found out, that the system starts perfect, if I start Setpatch with enabled option "NOCACHE" in the startup-sequence.

But now I only ran at half speed because of the lack of Caches

Any idea? Anyone?

I know the GVP 030 card came with a switch to map the 32bit RAM as Autoconfig (with all the problems that came, ie consideration for other cards) or as Extended, and iirc so did the 040 card. Double check the jumper for that.

Are you using a "vanilla" startup-sequence (and user-startup) or have you added stuff? Try a vanilla copy, and see if that helps. In fact, take it to basiss. Have just the 040 card in the Amiga, and a vanilla startup, and see if that causes the error to go away. Then add the Picasso, and latest software library. (leave the SD/FF in, that wont cause any problems iirc)

Ah, and make sure you got latest 040.library too.

Re the other cards, they might only take 64K RAM, but they can cause autoconfig issues with cards that take 2mb, of which you have 2 - the PII and the 040. I cant remember the details, and the PII manual explained this and the PIV manual doesnt, but its to do with where those 64K cards are mapped into the 8mb available.
