Hardware Interrupts<br />
If you add any PC/104 modules or other peripherals to the system you<br />
must ensure they do not use interrupts needed by the cpuModule, or<br />
malfunctions will occur<br />
The cpuModule supports the standard PC interrupts listed below. Interrupts not in use by hardware<br />
on the cpuModule itself are listed as 'available'.<br />
Hardware Interrupts Used on the cpuModule<br />
Interrupt Normal Use Source<br />
0 Timer 0 On-board ISA device<br />
1 Keyboard On-board ISA device<br />
2 Cascade of IRQ 8-15 On-board ISA device<br />
3 COM2 On-board ISA device<br />
4 COM1 On-board ISA device<br />
5 available XT bus<br />
6 Floppy 1 XT bus<br />
7 Printer On-board ISA device<br />
8 Real Time Clock On-board ISA device<br />
9 available, routed to IRQ<br />
2<br />
XT bus<br />
10 available AT bus<br />
11 available AT bus<br />
12 Bus mouse On-board ISA device<br />
14 IDE hard disk 2 AT bus<br />
15 available AT bus<br />

Floppy disk interrupt, INT6, is available for use if no floppy disk is present in the system and floppy<br />
disk is disabled in Setup.<br />
2 Hard disk interrupt, INT14, is available for use if no hard disk drive is present in the system and<br />
hard disk is disabled in Setup.<br />
