It also supports Voodoo 4,5 and S3 VirgeGX cards. (Not VirgeDX)
are you sure? All my PCI Virges are DX models and I had VirgeDX working (but special care had to be taken with drivers as you had to use p96 libraries/drivers supplied in the same update. Mixing the old virge driver with a more recent picasso96 library -or rtg, I can't remember- didn't work)
@Dandy
Well - it offers support for graphic cards, sound card, networking cards, USB cards, TV cards and the like - what kind of support are you missing?
AFAIK Sound, 100Mb networks, USB and TV cards don't work with Prometheus.
There are working drivers for catweasel MK3, Virge, Permedia2, Voodoo3/4/5 and RTL8029. But with Michael Boehmer update the cards that didn't work correctly will work :-)
