ISA drivers...

Hi everyone... a bit of an arb question now... I am writing an application to access an ISA card. I am using the instructions inp and outp  to access address 0x300 but those only work for win95. As I understand it, those instructions just read the card which sounds straight forward. Now for the arb question... if I want to use winNT or some strange platform that requires a driver, I must rewrite some code. In spite of looking like a fool now, I must ask what is a driver in laymans terms? What does it do that is so special and different from inp and outp? More importantly how does it do it and how does it work? How would my program read what the driver retrieves? And the next step is what are the steps I should follow to write my own driver. Stop laughing ;-) Thanks for any clues...

To enable the I/O access under Windows NT use the GIVEIO.SYS driver by Dale Roberts (http://http://www.ddj.com/ftp/1996/1996.05/directio.zip).

Also you can use the NTIOSUPP.DLL (by Andy Green) that allows you to load and start the GIVEIO.SYS by simple function call.

This isn't a right place for the "Introduction to driver development" course :) So what you need to do is:
1) Get the Win95 and WinNT DDKs from Microsoft
2) Read the Help
3) Compile the simplest samples ("SIMPLE" in the WinNT DDK)

Also I can suggest you to read the Art Baker's "The Windows NT Device Driver Book" and the Walter Oney's "Systems Programming for Windows 95"

>>How would my program read what the driver retrieves?
There are few ways the driver can communicate with the user mode application IOCTL, APC etc.
