VERY URGENT!!!!!structure of Configuration ROM for IEEE Host Controller(DVHS UNIT)

NTDEV
1

Hi,
I am creating a DVHS emulator device on IEEE bus. First i have created a virtual device and installed driver using 1394api.dll. Now i want to send a request of

REQUEST_SET_LOCAL_HOST_PROPERTIES with SET_LOCAL_HOST_PROPERTIES_MODIFY_CROM

to modify the Configuration ROM data of the local host controller. Can any body help me how the Unit Directory structure looks like and how can we fill up the parameters in the unit directory with sample for DVHS kind of devices.

IS there any other things i need to do apart from the above request In order to make the host controller as an DVHS Device emulator.

regards

There is a white paper on the WinHEC website about the layout of the config
rom for a generic device.
