I think these fizes would help your Plus...

Note: The following information is offered Ras isS and without 
warranties of any kind. Apple Computer neither supports nor recommends this procedure.

Hackintosh ResEdit Workaround, version 8/6/91

This information is intended to help people who have a RHackintosh PlusS 
(i.e., a Mac 512ke upgraded to a RPlusS via third party hardware) and 
running System 7.0. 

If you're getting the message RThe driver for the selected AppleTalk 
connection could not be found. The built-in LocalTalk port will be 
used insteadS at startup, these workarounds are for you.  There are 
yhree ways to fix this problem -- all require the use of ResEdit 2.1 
or higher.  These procedures require familiarity with the proper use 
of ResEdit. All of these methods work -- but they are not for the 
faint of heart.

Method #1: Note, If you use Method #1, you WILL NOT be able to use 
AppleTalk. This workaround is for people not using AppleTalk!

% The error message appears because the AppleTalk driver looks for 
an AppleTalk port, which it would have found if the computer was a 
"real" MacPlus Because the Mac was originally a 512E it wasn't finding 
such a port and the AppleTalk Driver RcomplainsS. Use ResEdit to open 
the System file (you get a message warning you to be careful, so click Ok), 
then open the DRVR resources, SELECT (don't open) the DRVR with the 
name ".ATP", then choose Clear from the Edit menu.  Close the System 
file and save changes. This cuts out the AppleTalk driver from the 
system file.

Method #2:

% Open the System file with ResEdit 2.1.1. Open the ALRT resource. 
Open ALRT -16407. From the new ALRT menu choose RSet TALRTU Stage Info...S. 
Set the 4 visible check boxes to off and the 4 sound flags to 0. 
Quit, Save and Reboot and the problem should be gone.

Method #3: 

% This patch prevents the alert box from interrupting and removing the 
startup screen and forcing you to wait to press the OK button.  
However, it should allow the procedure to do its normal correction for 
the "error" it detected. Use ResEdit to open up the System file and 
find the resource labeled "lmgr" and open it up.  There will only be 
one type of that resource. Open this resource and do a find command 
for the following hex string : 
"612C 610E 554F 3F03 42A7 A988 544F 281F 4E75 7200" and 
change it to : "4E71 610E 4E71 4E71 4E71 4E71 4E71 281F 4E75 7200" 
save the new resource and don't worry about the dialog box warning 
about being unable to compress the resource.


Method #2 & #3 allows you to still use AppleTalk, whereas with 
Method #1 (removing the AppleTalk Driver), you can not.
