Dear PCI friends,
I'm writing a Win NT Driver for my PCI
board.
I've instantiated on it a PCI MegaCore
Function for bus interfacing (bus mastering access to
system memory).
To initialize the function a bus master has to write to the configuration register (command register) to enable memory transfers and set the MegaCore to be a Master. Maybe the Bios does this job, but I'm
not familiar with Bios enumerating process. Any idea
about setting W/R configuration registers with WinNT
OS?
Thanks for
help.
