From: Don Burn on 1 Oct 2007 08:35 That article is only for Windows NT, not for Windows 2000/XP/2003/Vista or Longhorn. What do you mean by 2 drivers with interrupt in the same device? If you mean one interrupt and interrupt control register then you probably will need to write a bus driver if you want seperate drivers for the devices. If you mean sperate interrupts triggering on the same interrupt line, then just write your driver. Since you are new to this take a look at KMDF this will simplify you development a lot.

From: Maxim S. Shatskih on 4 Oct 2007 16:16 HalAssignSlotResources is obsolete since year 2000. Write a WDM PnP driver, possibly using KMDF framework. HalAssignSlotResources is NT4 function, using it in a driver will disable all power management on the machine. -- Maxim Shatskih, Windows DDK MVP StorageCraft Corporation maxim(a)storagecraft.com http://www.storagecraft.com "Hasitha" <Hasitha(a)discussions.microsoft.com> wrote in message news:C652F62D-3814-4AC3-A06A-3588B4CC420F(a)microsoft.com... > Hi all, > Thank you very much in advance. > > I am writing 3 drivers for one PCI device.

Yes my PCI device have 7 subsystems. each one have read write and IOCTRL functionality. 3 of them use interrupts. therefore i cannot write one driver for whole device. I have to write 7 separate drivers for each subsystems. What can i do to resolve this problem?
