NETWORK ADAPTER/A IN PERSONAL SYSTEM/2 MODELS 8550, 8555, 8560, 8565,
8570, 8580 AND 9585, TO AVOID HARDWARE ARBITRATION AND INTERRUPT LEVEL
CONFLICTS: LEVEL CONFLICTS:

1. WHEN INSTALLING THE 3270 CONNECTION ADAPTER, IT MUST BE
LOCATED IN THE LOWEST NUMBERED SLOT AVAILABLE, PREFERABLY
SLOT #1. THE 3270 CONNECTION ADAPTER USES ONLY INTERRUPT # 2.
REFER TO TDR #H025467 UNDER D/T3270 FOR MORE DETAILS.

2. WHEN INSTALLING THE TOKEN RING ADAPTER/A, IT SHOULD BE
IN A HIGHER NUMBERED SLOT THAN THE 3270 CONNECTION ADAPTER

USING THE REFERENCE DISKETTE, "CHANGE CONFIGURATION"
UTILITY ON THE "SET CONFIGURATION" MENU. SEE CAUTION BELOW.

************************* CAUTION ****************************

ONCE INTERRUPT LEVELS ARE SELECTED AS DESCRIBED ABOVE, AND HAVE
BEEN CHANGED THROUGH THE "SET CONFIGURATION" UTILITY, THEY MUST
BE SAVED USING THE "BACKUP CONFIGURATION" UTILITY ON THE "SET
CONFIGURATION" MENU. THIS WILL PROTECT USER SELECTED INTERRUPT
LEVELS FROM BEING CHANGED TO THEIR SYSTEM DEFAULT SETTINGS WHEN
THE "AUTOMATIC CONFIGURATION" UTILITY IS EXECUTED. SHOULD THE
AUTOMATIC CONFIGURATION UTILITY EVER BE EXECUTED, AND THE USER'S
PREVIOUSLY SELECTED INTERRUPT LEVELS ARE RESET TO THE SYSTEM
DEFAULTS, THE USER MAY THEN EXECUTE THE "RESTORE CONFIGURATION"
UTILITY ON THE "SET CONFIGURATION" MENU TO RESTORE THE INTERRUPT
LEVELS TO THOSE THAT WERE SAVED WITH THE "BACKUP CONFIGURATION"
UTILITY.

Hmm, I'll most likely create a special page for these more generic
issues that cover multiple models and adapters. (In the troubleshooting
section perhaps?) And then link to the individual articles from the
relevant adapter/planar pages.
