Hi All-
I need some quick advice. I tried to get my Prometheus graphic card working on my A4000 last weekend. Ran long enough to convince me I want a graphics card, but crashed unpredictably (sometimes when I moved mouse, or opened program, or closed program that had opened successfully.) I striped out all my speed-up hacks and ran box-stock OS3.9, which helped a little (I think- very unpredictable). Is this where Buster chip revisions crop up, or is my quaddoubler '04 speedup CPU card making timing problems (its been rock solid for years otherwise)?
The Prometheus seems to eat about 4meg memory whenever I plug it in. Is this common? And if so, would another graphic card leave me with all 16 megs of memory? Any recommendations will be welcome. I'm aiming for a system that will let me run Hollywood for development purposes.
Yours-
CRL

Check if you've got a Voodoo 3 card on the Prometheus, Banshees et al are reported to run unreliably.
I've not come around to install my Promy yet, so I've got no idea what amount of memory the driver eats up (probably a fast RAM copy of the frame buffer). RTG does eat up quite a bit of RAM, as does my Merlin.

try to get a permedia 2 chipset.I suppose it is the most compatible one if i judge from the fact that phase5 chose that chipset instead of everything else.
And it is quite enough for Classic amiga operations.
the 4mb issue might be because of the dma,but i am not sure.
Be sure to install the latest firmware available.
you can find referances here in amiga.org.
