Dear all,
Now, I must write a application that can read and write arbitrary IO port
under 98 and NT.
Under Windows 98:
I write a Win32 application that read and write all IO port,it can be
compiled and runned.
When I run it, no GP error occur, but system crashed with no keyboard and
mouse reaction.
So, all IO port can be read/write, but it is not safe to write some
critical port ,
am I right?
Under Windows NT:
The portio sample is not fit for my need.I should can read/write all
arbitrary port.But
portio only can claim partial IO port,it is silly to claim all port in
portio.
What can I do?
Help me please.
Thanks.

Get a copy of Cris Cant’s book _Writing Windows WDM Device Drivers.
There are on the CDROM generic drivers for both WinNT and Win2k
that permit the reading/writing of arbitrary i/o port addresses.
Source is included. Using this code will save you a lot of time.
