great, thanks for the tips, not having to use the mach64 is good because i can't use all 3 of my PCI slots and my soundblaster at the same time because the idiot who designed my motherboard put the PCI and ISA slots too close together.

got my SLI cable made so i'll try out this setup tomorrow.

are mismatched vendors a problem? i can get a 12mb gainward dragon for a reasonable price.
also its not a reference design card and my 12mb one is a ct6670 which is, does that matter?

does wickedGL do the same thing as miniGL? also do i need mesaFX as well as wickedGL? i assume i need the glide2x/3x files from koolsmokie's kit in my system folder too.

thanks again and sorry for asking so much at once, these are my first 3dfx cards!

i found an old k6-2 system and decided to make a dos gaming box since dosbox always seems to give me nasty glitchy sound. the pci integrated sound on the mobo is not exactly dos friendly so i hit ebay to look for an SB16 and found one with some assorted pci/isa cards including a mach 64 and 12mb creative voodoo2. so i thought why not make a dualboot freeDOS/98SE gaming system. there was a seemingly indentical ct6670 card up for grabs so i bought that too.

but problem is when it arrived it was only 8mb, damn creative made 8mb and 12mb with the same model number. also the mach64 turned out to be a crappy xpression 1mb version which doesn't look like it can do 1024x768 at anything better than 256colour, not sure if its a driver issue or the amount of memory

so possible solutions could be to just run the 12 and 8mb cards in sli which from what i read should work, the 12mb card will restrict itself to 8mb?
desolder 2 of the dram chips from each of the texture processors of the 12mb card and install them in the spare slots of the 8mb card, i dont know if this would work or if it would require a modified bios or something.
buy another 12mb card off ebay, theres a gainward dragon on there which would be pretty nice, will a non-reference design board work in sli with a reference design one though?

i theory the mach64 card can be upgraded to 2mb ram but i have no idea where to get the edo dram chips to do it, im guessing they would need to be a specific type with the right pinout.

would it be possible to use the onboard graphics to handle 2d while still using the voodoo2s for 3d? its a jetway 531cf (SIS 530 chipset) with SIS 6326 agp graphics chip which is 3d capable, how would i make sure programs use the voodoo2s?

thanks for any help.
