Video card with more than 32mb of video ram with P/I-P55T2P4 and TX97-E boards

Hi,

I have been trying to install new PCI video cards such as GeforceFX-5200 pci
128mb and Geforce4mx 64mb and geforce2mx 64mb pci cards in these two
motherboards. Both behave as if there is no video card installed. However
both will work with a nVidia TNT1 16mb pci card and with a Geforce2mx 32mb
card and with a Voodoo5 5500 64mb pci card.

Is there a bios bug in these boards that prevent the use of a framebuffer of
more than 32mb?

Thanks.

 

My friend had a similar problems with PCI video card, it wouldnt boot with a
64 mb one, but it did boot fine with an AGP 64 meg card. I think it might
be related to the amount of current the newer pci cards draw (speculation)

 

I've seen the same thing, but it may not be the amount of memory, but
the configuration. I CAN run a 64 MB (8 chips) GF2 MX in my TX97-XE,
but it won't run a 64 MB (4 chips) GF2 MX, or a 64 MB GF4 MX440, or a 64
MB (2 chips) Radeon 7500. With new PCI vid cards using fewer memory
chips with more memory per chip, you may be restricted. The highest
level 64 MB card I've seen with 8 chips was a Hercules Radeon 9000, but
they were short-lived, and I believe restricted to Europe.
