I/O Port IRQ Selection
The parallel port and both serial ports must have their IRQs. Normally, these settings can be left in
their default settings and only when conflicts arise should they be changed. Jumper JP20 is used to
select the parallel port IRQ. Jumper JP19 is used to select the first serial port’s IRQ. Jumper JP18
is used to select the second serial port’s IRQ. Use Table 1-8 to select the IRQs for these options.

The IDE interfaces can be configured in the BIOS.
Clock Speed Selection
The jumpers JP2, JP7 and JP26 allow you to choose the appropriate CPU speed, without changing
crystals and oscillators.
