ABSTRACT:
Among devices on the system board, all devices other than those devices essential to the operation of the system such as system timer 19 and real-time clock 20, i.e., I/O devices 24 and 25, are constructed such that their environment may be configured and changed. If the hardware resources allocated to I/O devices 24 and 25, such as I/O address areas, interrupt levels, etc., overlap with the hardware resources requested by option cards 32 or 33, the hardware resources allocated to I/O devices 24 and 25 are automatically changed. As a result, the internal I/O devices and option boards can always be made to operate normally, regardless of the values set for the I/O address areas, etc., for option cards 32 and 33.
