SCSI support: This contains all the options related to SCSI disks and peripherals. If you have a SCSI-based system, be sure to enable "SCSI support", "SCSI disk support", "SCSI CD-ROM support", and "SCSI tape support" as necessary. If you are booting from a SCSI disk, ensure that both "SCSI support" and "SCSI disk support" are compiled-in to your kernel and are not selected to be compiled as loadable modules. For SCSI to work correctly, you need to perform one additional step: head over to the "SCSI low-level drivers" sub-category and ensure that support for your particular SCSI card is enabled and configured to be compiled directly into the kernel.
