Kernel Mode Driver for NT

Thanx for all reply!
Especially to ColdCoder for the cool links. Big Thanx!

I try to reply to all of you in one session...

I don't have DriverStudio,
but as I know these tools like NuMega's one
needs DDK for complete development too.
(I was tried Jungo WinDriver suite.)

I need only direct Port I/O,
but I need to build _my own_ Kernel Mode Driver,
thats why I need Windows DDK.

EnTech doesnt release their sources for free,
so this components are useless for me.

GiveIO, WinIO and PortTalk are has very usefull sources,
but all need DDK to build the binaries.

Conclusion... atm, I'm working on my own "PortIO.sys"
based on GiveIO and coded in MASM32 using KmdKit,
Windows DDK's and the above sources
must be enough to finish my job.

Thx again.

p.s.: If I success then I post the source here, maybe somebody will like it.
