Routine Description:
|
||
|
||
Determines the canonical short machine name for the HAL to be loaded for
|
||
this machine.
|
||
|
||
It does this by enumerating the [Map.Computer] section of the INF file and
|
||
comparing the strings there with the computer description in the ARC tree.

Arguments:

None.

Return Value:

PCHAR - pointer to canonical shortname for the machine.
|
||
NULL - the type of machine could not be determined.
