IBM PC730/PC750 - SDLC adapters fail
Applicable to: World-Wide
Service Information:
SDLC adapters may fail to function properly or fail to be recognised by the system when installed in an IBM PC 700 Series system.
The Business Audio function of the PC 700 system board is hardwired at I/O address 388-38B. This I/O address may conflict with most SDLC adapters. For example, the IBM Multi-Protocol Adapter (MPCA) defaults to I/O address 380-38F which conflicts with the Business Audio feature. The MPCA adapter can be reset to 3A0-3AF to eliminate the conflict. Change the I/O address (Mode) of the SDLC adapter to an address that does not conflict with I/O address 388-38B or disable the Business Audio feature via the Setup Utility.
