Note 1
The following interrupts are used by the system: IRQ 0 (Timer), IRQ 1 (Keyboard), IRQ 6 (Floppy Diskette Drive), IRQ 8 (Real-time Clock), IRQ 12 (Mouse/TrackPoint), IRQ 13 (Math Coprocessor), and IRQ 14 (Hard Disk Drive).
Note 2
If you enable the second hard disk drive in the UltraBay, it must use IRQ 15. This could cause a conflict with an existing device.
