WDM driver loading in Windows 98

NTDEV
1

I have a multiportserial card driver for windows
2000(which follows the WDM guidelines
programmatically, but hasnt been tested for cross-OS
compatibility), that I need to make WDM compliant. I
have a few queries.

  1. Are there specific calls that would work on Windows
    2000 whose symbols windows 98/Me might not resolve(and
    hence not load the driver)?

  2. Would the co-installer dll (that works on windows

  1. work on windows 98 and if so what would be
    registry key that should be accessed for using it?
  1. The Ntkern.vxd that is supposed to be the support
    module (Deviceloader) for windows 98 wdm drivers does
    not load the win 2k driver I have. It returns code 2
    in the device manager. The driver file details are
    displayed correctly though. Anyone has any pointers on
    what could be possible reasons for this?

I would like to know if I should first be looking at
the driver code or installation procedure to get this
working.

Thanks

Install the checked version of VxDLDR.VxD to the folder System\VMM32
(this will be a new file to that folder, not a replacement; to remove
the checked version, just delete the file). It will report why your
driver is not loading to the Kernel debugger (RTERM98) including the
module and function name that is prohibiting your driver from loading.
