the following message.

I am not very sure about the 0x24 Error.
Anybody having any idea about this.
Thanks in advance,
Gurpreet

    Hi,
    I have developed a IFS for NT 4.0.
    I want to port it for Win2k,what major differences
    does both OS carries with respect to FS.
    I know there are some changes in the Driver Entry
    point
    I have read the Windows NT Device Driver Book By
    Anthony Mason which speaks of 3 phases in the Driver
    Entry level.Driver Entry does only the initialisation
    of the Dispatch routines including IRP_MJ_PNP and
    AddDevice.
    I am not able to understand the parameter
    PhysicalDeviceObject in the AddDevice() routine,
    Does it carries any significance with respect to
    FileSystem.What if I would like to do is to attach to
    a disk with a particular signature written on it.

    Second, with regard to IRP_MJ_PNP, what sigificance it
    carries with respect to a FileSystem Driver.

    Thanks in Advance.
    Gurpreet
