KMDF and legacy devices

NTDEV
1

Hi all,
I have to port a Linux device driver for a PC104 board to XP.
I
would like to use KMDF 1.1 as I found it very very usefull when writing
USB device driver but I am a little confused about the general
architecture for a legacy board.
Should I write it as a root-enumerated
PNP device driver OR do I have to use “Control Device Objects” only ?

Best regards,
PaoloC

If by ‘legacy board’ you mean that it looks like an ISA device then you
should write a PnP ISA device driver for it using WDF. You will have to
write an inf file describing its resource requirements.

Thanx a lot Mark for your support,
I will follow your suggestion.

Can
you please explain what kind of devices are “legacy hardware device”
mentioned in “Using Control Device Objects” of KMDF documentation:

“Drivers can use control device objects to represent software-only
virtual devices or legacy hardware devices (that is, devices that do
not provide PnP or power management capabilities).”

Best regards,
PaoloC
