2-4 System Configuration
Serial Port Interrupts
The interrupts for serial port 1 and serial port 2 are given in the following table.
Any interrupts used for the built-in serial ports are not available for ISA parallel
ports. Also, if serial ports share an interrupt, verify that hardware and software
added to the system can share these interrupts without problems.

Jumpers on the boards and devices in the system are used to set the system
configuration. Boards and devices using jumpers include:

only the setting for that condition (see Section 4 and
