How do I port a DOS driver, which uses inp() and outp() calls to access the card, into a Windows driver?

Simple! Include the sample basic_io.c source code (found under the WinDriver/samples/basic_io/ directory) in your code.
Define the I/O range your card uses in MY_IO_BASE and MY_IO_SIZE.
[For example: To use range 0x378-0x37a, define MY_IO_BASE=0x378 and MY_IO_SIZE=3].
Call IO_init() at the beginning of the driver, and IO_end() before exit.
Replace any inp() and outp() calls in your code with IO_inp() and IO_outp(), respectively.
Compile and run!
