GVP Impact Series II 2000 HC+8 & PicassoIV conflict

[KptAmiga]

I have an A2000 which has a SCSI HD and extra RAM by way of a GVP Impact Series II 2000 HC+8 Rev. 4 (http://www.amiga-hardware.com/gvphc8_big.jpg). Recently, I acquired a PicassoIV card for it.
Either card works fine and dandy by itself, but together they're trouble... All I get is a yellow screen and constant resets (pre-boot).

I don't have the manual for the GVP card, so I'm not inclined to touch any of the jumpers (because, frankly, I don't see how changing any of them might help). I do suspect that there's a memory conflict, since I've read that the Picasso card requires other expansion cards to place their memory in extended modus. I've tried limiting the memory the Picasso card uses by closing jumper 1, but that didn't help, so I'm guessing I have to do something with the GVP card.

Does anyone know how to make them work together?

You can only have a max of 8 meg on the zorro bus on the 2000 . So 4 meg on the video card and 4 meg on the GVP should boot..

Ah, I didn't know that.

Ok, I removed the extra ram modules on the Impact card so that it now only has 4 megs (total for system is 5 megs, with one meg chip ram). I now get a new error, "gvpscsi.device. Unexpected Status, Unit XXX (no. changes)" & a continue button...

I moved a GVP SCSI card and GVP IO card from an
an Amiga 2000 to my A4000 and added a GVP Spectrum
card. After weeks of trial and error testing,
I discovered that I could only get all 3 cards
working properly if they were in the slots in
a particular order. I had to put the Graphics
card in the slot closest to the motherboard,
the IO card in the next closest slot and the
SCSI card in the slot furthest from the MB.
I have no idea why the order matters, but in
my case it does. If you get desperate, you might
try shuffling the cards around. No guarantees,
but it might make a difference.

The Picasso IV was designed to work with the Zorro III Amiga computers.  It does not work too well in an Amiga 2000.  Try using a Picasso II instead.  It was designed for the Amiga 2000 and works much better then the Picasso IV.

Wow, Doomy, that would be a really interesting point of view IF YOU WERE RIGHT, AND YOU'RE NOT.  From the Big Book of Amiga Hardware (www.amiga-hardware.com) :

The Picasso IV is a Zorro III and III auto-sensing graphics card. It has a pixel clock of 135Mhz (8bit), 85Mhz (16bit) and 85Mhz (24bit). It contains a built in 100Hz flicker fixer. If the Picasso IV is intended for use in an A2000, the flicker fixer can actually be "snapped" from the card and joined to it by a ribbon cable. This is because the A2000 does not have an inline video slot, like other models. It also contains a local PCI expansion bus, for which several add-on cards were made, such as the Paloma IV TV Card, the Pablo IV video encoder, and the Concierto sound card. A 3D module based around the VooDoo chipset, and a MPEG module were planned, but unfortunately were never released. The card also contains a 4-channel audio mixer, a CDROM input connector, a Flash ROM controller (for updating the firmware) and is endian agnostic.

Jumpers Jumper Open Closed
1 4MB RAM Force 2MB RAM
2 Auto-Sensing Force Zorro II
3 Forced 24bit flickerfixer 24bit & 12bit auto-sensing flickerfixer
4 Sync on Green disabled Sync on Green Enabled

6 Reserved, Default DO NOT CLOSE

Lots of people use Picasso-IVs in their A2000s, you {bleep}.
