One of the most common causes of problems both during and after installation is a device interrupt conflict. Make sure device interrupts do not conflict and do not use the reserved interrupts indicated in ``Typical device interrupts'' or your system will probably fail to boot.
Typical device interrupts
|2||2||Networks, tapes and others|
|5||5||Alternate parallel port (lp2)|
|7||7||Main parallel port (lp0 or lp1)|
|9||11||Chain from IRQ2|
|11||13||SCSI host adapter 0|
|12||14||SCSI host adapter 1|
|14||16||ST506/ESDI/IDE controller 0|
|15||17||ST506/ESDI/IDE controller 1|
Do not attempt to use these interrupts for any other purpose.
