CONFIG_SCSI_NCR53C8XX_IOMAPPED: use normal IO

General informations

The Linux kernel configuration item CONFIG_SCSI_NCR53C8XX_IOMAPPED has multiple definitions:

use normal IO found in drivers/scsi/Kconfig

The configuration item CONFIG_SCSI_NCR53C8XX_IOMAPPED:

Help text

If you say Y here, the driver will use normal IO, as opposed to memory mapped IO. Memory mapped IO has less latency than normal IO and works for most Intel-based hardware. Under Linux/Alpha only normal IO is currently supported by the driver and so, this option has no effect on those systems.

The normal answer therefore is N; try Y only if you encounter SCSI related problems.
