CONFIG_SCSI_SYM53C8XX: SYM53C8XX SCSI support

General informations

The Linux kernel configuration item CONFIG_SCSI_SYM53C8XX has multiple definitions:

SYM53C8XX SCSI support found in drivers/scsi/Kconfig

The configuration item CONFIG_SCSI_SYM53C8XX:

Help text

This driver supports all the features of recent 53C8XX chips (used in PCI SCSI controllers), notably the hardware phase mismatch feature of the SYM53C896.

Older versions of the 53C8XX chips are not supported by this driver. If your system uses either a 810 rev. < 16, a 815, or a 825 rev. < 16 PCI SCSI processor, you must use the generic NCR53C8XX driver ("NCR53C8XX SCSI support" above) or configure both the NCR53C8XX and this SYM53C8XX drivers either as module or linked to the kernel image.

When both drivers are linked into the kernel, the SYM53C8XX driver is called first at initialization and you can use the 'excl=ioaddr' driver boot option to exclude attachment of adapters by the SYM53C8XX driver. For example, entering 'sym53c8xx=excl:0xb400,excl=0xc000' at the lilo prompt prevents adapters at io address 0xb400 and 0xc000 from being attached by the SYM53C8XX driver, thus allowing the NCR53C8XX driver to attach them. The 'excl' option is also supported by the NCR53C8XX driver.

Please read Documentation/scsi/ncr53c8xx.txt for more information.
