Where to put IO port adddress in inf file and what is purpose of
following sections in genport.inf
[ WINDDK\3790\src\general\portio\genport.inf ].

[PortIO.LC0]
ConfigPriority=DESIRED
IOConfig=378-37b(3ff: ; 10 bit decode ranging from 300 - 303

[PortIO.LC1]

Hmm , just read the "parallel port" thread and i think its gonna work
for me
IoConfig=378-37a but do i have to tell inf about interrrupt? which my
driver will use , by default system assigns IRQ 7 to LPT1.

Thanks in advance.

Hi, this is Wolfgang (nwk), who started the "parallel port" thread.

I'm curious whether it will work for you. Which OS (W2k, XP) do you use?

My .INF file includes:

IoConfig=378-37a
IRQConfig=7

btw: thanks for your answer to my FAQ question

I am using Microsoft Windows XP [Version 5.1.2600] on built-in EPC

capablity Intel board.

Well havn't tried inf file so far but just did a little trick and

still observing. I have tried the following steps :

*) Control Panel \ System \ Device manager \ ECP Printer Port(LPT1)

Now i can atleast see success from CreateFile but WriteFile is never
returning back to me;-) waiting for freeze application.

Well i'm still not very sure for inf file. The ddk\portio\genport.inf
sample loos good to me but don't know how to just say that i want 378
to 37A ports with IRQ 7 and Nothing. NO DMA , or extra ports;-)
I'll let you know if it works:


I'm using folowing settings, thanks to Don for DevCon clue , really
handy stuff and smells Unix machine. l0l

Forget to paste:

Hi
The loopback parallel port device is not getting recognized by PnP driver in WINXP. The driver is an upper filer and gets intalled using a registry script as shown above by "Ali". Even, Found new hardware is also not recognizing the loopback device. Any help?
I have enabled use any interrupt assigned to this port and legacy plug and play support.

Thanks in advance.
