Routine Description:
|
|||
|
|
|
|||
|
|
This function returns the system ID, which consists of an eight byte
|
|||
|
|
VendorId and an eight byte ProductId (in this case the ethernet address).

|
|||

Arguments:

Return Value:
|

|
|
|||
|
|
Returns a pointer to a buffer containing the system id structure. This
|
|||
|
|
structure is initialized on each call to prevent programs from changing
|
|||
|
|
the value.
