Subject

Games set in MPU-401/MT-32 UART mode would hang the PC randomly.


Description

Games set in the MPU-401/MT-32 UART mode at default I/O address 330H 
would hang the PC when played. These games will detect the MPU-401 
interface present on the SB 16/ASP and would issue MPU-401 commands to it. 
The games hang when they issue non MPU-401 commands to the MPU-401 
port.


Solution/Action

To correct the problem, users would have to switch the MSEL jumper from the 
default address 330H to 300H.
