I have flashed a Mac PCI version of a 5500 to 1.18 for PC.  I used the bios files found at http://3dfxbios.stantoworld.co.uk/

My question is, what is the difference between these two in the Voodoo5 section?

# 1.18 (MD5) (Digital Output Enabled, States: v4)
# 1.18 (MD5) (Digital Output Enabled, States: v5)

I used the one marked v5.  Seems to work, but I am having trouble when I have another non 3dfx AGP card in use for a dual monitor setup.  Get distorted images on the 3dfx dvi port.   Vga port works fine in that setup though.

Any ideas?
