This routine finds the instances of a physical adapter identified

NOTE: That for now there is only one card supported by this file,

some processing time.

lNetcardId - The index of the netcard being address. The first

cards information is id 1000, the second id 1100, etc.

|
|
|
InterfaceType - Either Isa, or Eisa.
|
|
|
|
BusNumber - The bus number of the bus to search.
|
|
|
|
fFirst - TRUE is we are to search for the first instance of an
|
|
adapter, FALSE if we are to continue search from a previous stopping
|
|
point.
|
|
|
|
ppvToken - A pointer to a handle to return to identify the found

|
instance

that the card exists.
