9.Run any configuration software required to complete the installation of the add-in board.
Configuring Add-in Parallel Ports and Sound Cards
If you install an add-in board with a parallel port, it must be configured to use an interrupt other than IRQ7, since that interrupt is reserved for the onboard parallel port. Optionally, you can disable the onboard parallel port. Refer to the Peripheral Configuration section of the Advanced Options part of System Setup for more information.
If you install an add-in sound card, disable the integrated audio adapter. Refer to the Audio Configuration section of the Advanced Options part of System Setup for more information.
Installing Drives
One 3.5-inch floppy drive, one 3.5-inch hard drive, one Zip drive, and one CD-ROM drive come with your computer. You can add one additional floppy drive and one additional IDE drive. Examples of additional drives are:
∙Half-height 3.5- or 5.25-inch floppy drives. The system board has a floppy controller that supports up to two floppy drives, one of which is the 3.5-inch drive that comes with the computer.
∙Half-height 3.5- or 5.25-inch hard drives.
The system board has two IDE connectors that support up to two drives each.
To use another type of hard drive, such as a SCSI drive, install an add-in hard drive controller board.
∙Tape backup. Some models of tape backup drive can use the onboard floppy controller; other models require add- in controllers.
Before installing a drive, read the instructions for preparing the drive. You can then install a drive on any of the drive-mounting brackets located inside the computer (Figure 13).
