How to access PCI BIOS functions in 32-bit mode?
I know that in 16-bit mode they are acessible through int 1A, but in flat model you should call functions using the entry point in some physical address. How to call a function, if I know its physical address? Should I use _mapphystolinear or something else?
Thank you. :)

In most cases this isn't possible because BIOS code is 16-Bit and would be misinterpreted if executed in a flat model.

But if you are writing a Vxd, you can execute V86 mode ints without problems
