Unless you have an NCR manufactured machine, the chances are that
you do not have this SCSI card, so say N.
-config SCSI_SYM53C8XX
- tristate "SYM53C8XX SCSI support"
- depends on PCI && SCSI_SYM53C8XX_2!=y && SCSI
- ---help---
- 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 <file:Documentation/scsi/ncr53c8xx.txt> for more
- information.

This option allows you to specify the maximum number of commands

bool " enable profiling"
- depends on (SCSI_SYM53C8XX || SCSI_ZALON || SCSI_NCR_Q720)
+ depends on SCSI_ZALON || SCSI_NCR_Q720
help
This option allows you to enable profiling information gathering.
These statistics are not very accurate due to the low frequency
The normal answer therefore is N.
-config SCSI_NCR53C8XX_IOMAPPED
- bool " use normal IO"
- depends on SCSI_SYM53C8XX && !(SCSI_ZALON || SCSI_NCR_Q720)
- help
- 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.
-
-config SCSI_NCR53C8XX_PQS_PDS
- bool " include support for the NCR PQS/PDS SCSI card"
- depends on SCSI_SYM53C8XX
- help
- Say Y here if you have a special SCSI adapter produced by NCR
- corporation called a PCI Quad SCSI or PCI Dual SCSI. You do not need
- this if you do not have one of these adapters. However, since this
- device is detected as a specific PCI device, this option is quite
- safe.
-
- The common answer here is N, but answering Y is safe.
-
config SCSI_NCR53C8XX_NO_DISCONNECT
bool " not allow targets to disconnect"
- depends on (SCSI_SYM53C8XX || SCSI_ZALON || SCSI_NCR_Q720) && SCSI_NCR53C8XX_DEFAULT_TAGS=0
+ depends on (SCSI_ZALON || SCSI_NCR_Q720) && SCSI_NCR53C8XX_DEFAULT_TAGS=0
help
This option is only provided for safety if you suspect some SCSI
device of yours to not support properly the target-disconnect
not allow targets to disconnect is not reasonable if there is more
than 1 device on a SCSI bus. The normal answer therefore is N.
-config SCSI_NCR53C8XX_SYMBIOS_COMPAT
- bool " assume boards are SYMBIOS compatible (EXPERIMENTAL)"
- depends on (SCSI_SYM53C8XX || SCSI_ZALON || SCSI_NCR_Q720 ) && EXPERIMENTAL
- ---help---
- This option allows you to enable some features depending on GPIO
- wiring. These General Purpose Input/Output pins can be used for
- vendor specific features or implementation of the standard SYMBIOS
- features. Genuine SYMBIOS controllers use GPIO0 in output for
- controller LED and GPIO3 bit as a flag indicating
- singled-ended/differential interface. The Tekram DC-390U/F boards
- uses a different GPIO wiring.
-
- Your answer to this question is ignored if all your controllers have
- NVRAM, since the driver is able to detect the board type from the
- NVRAM format.
-
- If all the controllers in your system are genuine SYMBIOS boards or
- use BIOS and drivers from SYMBIOS, you would want to say Y here,
- otherwise N. N is the safe answer.
