If you run the Microsoft Mail (PC Client) program before loading the
AppleTalk driver software provided with your AppleTalk network card,
you may receive the following message upon starting Mail:
You need to run the AppleTalk device driver software before
starting Mail.
This message may also appear if Mail did not locate the AppleTalk
driver at a specific software interrupt address. Mail keeps track of
the AppleTalk driver's location through the MAIL.INI file, which is
located in the Mail program directory.
AppleTalk protocol requires that the AppleTalk driver be loaded within
the software interrupt address range 5C-6F. PC Client Mail uses
software interrupt address 60 as the default value when locating the
AppleTalk driver.
If Mail Setup locates the AppleTalk driver at a software interrupt
address other than 60, it will add the statement INT=XX to the
MAIL.INI file to inform Mail that the driver will not be found in the
default software interrupt address. You may also need to inform the
device driver to load at this address through a /INT=XX parameter (for
example, ALAP /INT=60).
