This dialog lets you change the destination directory for the installation and which drivers to install. If you wish to modify the settings of your AdvanSys SCSI adapter, you can do so by pressing [Control]-A when your computer is booting. Disk Driver - this driver will control hard disks and removeable drives. It is not required to use hard drives, since the BIOS on your AdvanSys adapter has the same functions but it gives better performance than the BIOS. CD Driver - this driver is required to use CD-ROM drives with your AdvanSys SCSI adapter. Install Directory - This lets you choose the directory for installing your AdvanSys software.
