G-REX PCI 1200 problems

[CLS2086]

Hi,
I might help you
My setup
So please tell me :

0 - Go to the Grex unofficial site and use the LASTEST Firmware without pluggin any card on the PCi bus !! Put 64mb at least.

1 - how do you power it ? AT or ATX PSU or by the floppy connector on the motherboard (don't do that !!!), or by the old amiga power connector (don't do that too !!!). Try to check the psu connectors when the machine is 'loaded'.

2 - Is the link between the BPPC/module/GREX are all 3 perfect ?

3 - Is the link between the BPPC/module done by metalic screews ? (ground + securities for the connector)

4 - Does your PCi cards are deeply plugged in theirs slots ?? I had a joke with cards in time even on PC  :crazy:

5 - What kind of Grex1200 do you have ? do you have the label "Neue Edition" with red wires like mine ?

or is it an updated model with some green wires ?

6 - which cards did you try and which order do you put them ?
My suggestion :
PCI control menu
On the 1st slot (closest to PSU connectors), Network card, then Sound Card, and in the last slot the Voodoo3

But when you press the ESC at startup you must get the BPPC menu with a voodoo3 and permedia2 card.

To power up it well with ATX you need a trick :
put a wire between the green cable and a black one.
Check if you have more than 4.86v for +5V !!

If it's not powered properly by the AT or ATX connector, it won't work well.

But don't use the floppy connector with GREX !!
If you have a connection or ground problem you can destroy all...

About your Voodoo, are you sure that it doesn't content the MAC firmware ? Can you test it and reflash it on a PC with firmware 2.x ?

I had no luck with the bridge it didn't work for me last time it tried.

maybe it's, but before I sent my BPPCs to DCE for the upgrade I could get a basic WB (320x200-4 colors) on the voodoo3 and AGA together !

Have you tried to reflash it with the FORCE option ?
How do you power it now ? what are the voltage ?
Did you try to boot on MorphOS 1.4.5 PowerUp Edition (take care about the IDE trick !!!)

hi,

PCIscan still says that cybpci.library couldn't be opened

It seems to me be a Warp conflict.

Please, try to boot on a fresh and clean OS3.1 or 3.9 without any patch or "kicksomething", and put your voodoo on the 1st slot (closest to PSU connector), try just a RTL8029AS network card then try to put the network card close to it and try to swap
Do you have a mono or dual DMA model ?
