Hi,

I write a program runs well in win9x. But it does not run in winnt. I found that I had used _inp(), _outp() functions for win9x version.

Have you got any sample code help me write data to port directly in winnt?

Thank you very much!

Can't be done from an app due to NT's virtualized addressing scheme. The only software that can write to hardware in NT are kernel mode drivers.

It can be done with WinIO, have a look at AsmIO at my website: www.madwizard.org.
