A friend of mine is trying to install the Prometheus Card and Voodoo on his Amiga 4000 without luck.. He can install the Prometheus Driver ( from the Prometheus original cd ). He has installed also the Picasso96 2.1b and everything is fine. The problem arrives when he tries to configure the screenmode on Picasso96Mode. When the Amiga 4000 boots up everything is fine, the workbench appears on Pal ScreenMode and on the LCD Monitor the Led light turns from yellow light to green light ( this means that the monitor receives the signal ).
When he launches Picasso96Mode he sees the list of the all video mode available, ready to be configured and tested
But when he tries to edit a video mode everything freezes, there is no way to prevent this..
Sometimes the system doesn't freeze but the LCD screen is totally black..
Only one time he was able to see the workbench on the LCD screen, but after he performed a reset ( as Picasso96Mode required it ), the workbench appeared again on the Pal Screen..
He tried two Voodoo Boards on the Amiga and on a PC. On PC they worked without problems, on the Amiga not..
He can see the Prometheus Board listed on the available card on the Early Startup Menu of Amiga OS and he can see the Prometheus and Voodoo Card listed as PCI device with the utility of Prometheus.
Maybe there is something that he is missing ?
Any idea ?

Thanks

Configuration :

AMIGA 4000 kickstart 3.1
SuberBuster 11
Cpu 68030 25 Mhz with FPU 68882
16 FastRam
A2320 Scandoubler Commodore
Prometheus PCI
Voodoo 3 2000 PCI 16 Mb
Amiga OS 3.9

In the past, I tried to use the Prometheus with Voodoo 3 myself, and I couldn't get it to work on the stock A4000 030 board, I think it's something to do with the lack of an MMU. I later fitted an 060 card and it worked perfectly. I've since heard it should work with the commodore 3640 040 board.

@Robert17

So do you think it could be a problem related to the 030 board ?

Yes, in my experience the Voodoo and Prometheus combination don't work with the commodore 030 board.

Ok the problem was the missing of MMU on the 030 and my friend found an utility on aminet to manage this and infact now it works !

That's the utility and that's what reported on the prometheus docs about is :

Quote:

Prometheus is a transparent Zorro III to PCI bridge. Each Zorro III transaction is translated to the appropriate PCI transaction. Transparency means that no special data read/write functions for PCI cards are needed. The cards can be treated as CPU address areas of the Amiga system. However, please pay attention to the CPU cache memory. AutoConfig procedures of the AmigaOS automatically disable the CPU cache for the address spaces taken by Prometheus. It is possible for MMU equipped CPUs, so problems appear when we deal with a 68EC030 CPU which does not have a MMU unit. In such cases, the cache memory can be flushed by the CacheClearU() or better CacheClearE() function that can flush only data cache.

and using this utility he solved the problem thanks for the info, without it he wouldn't able to make it works !
