To compile this driver as a module, choose M here: the
module will be called qlogicfas.
config SCSI_QLOGIC_ISP
tristate "Qlogic ISP SCSI support (old driver)"

---help---
This driver works for all QLogic PCI SCSI host adapters (IQ-PCI,
IQ-PCI-10, IQ_PCI-D) except for the PCI-basic card. (This latter
card is supported by the "AM53/79C974 PCI SCSI" driver.)
If you say Y here, make sure to choose "BIOS" at the question "PCI
access mode".
Please read the file <file:Documentation/scsi/qlogicisp.txt>. You
should also read the SCSI-HOWTO, available from
<http://www.tldp.org/docs.html#howto>.
To compile this driver as a module, choose M here: the
module will be called qlogicisp.
These days the hardware is also supported by the more modern qla1280
driver. In doubt use that one instead of qlogicisp.

help
Say Y here if you have a QLogic ISP1020/1040 SCSI host adapter and
do not want to use the old driver. This option enables support in
the qla1280 driver for those host adapters.
