I have a problem concering converting Win 9x code to NT/2k. The original code finds the irq and hardware I/O adress of a PCI card. It is coded in asm. When I try to run it in NT it ofcourse doesn''t work. Now could anyone tell me how I could do this same procedure through API calls or however it is supposed to be done in NT/2K? Thanks for the help... Admkirk
