wdex is the device driver for
Western Digital 7000ex (EISA bus)
SCSI host adapter cards.
In DACB mode, the WD7000ex uses the wdex driver.
In ASC mode, the WD7000ex emulates the Western Digital
WD7000 ISA bus host adapter, and uses
the wdha driver.
Before installing the 7000ex, set the card

Configuring the wdex driver
You can configure the wdex driver using entries in
/etc/conf/cf.d/mdevice and /etc/conf/sdevice.d/wdex.
Changes to these files
will only take effect if the kernel is relinked using
and the machine rebooted.
Configure wdex driver-specific characteristics
by editing the /etc/conf/pack.d/wdex/space.c file.
The wdex driver
supports all standard SCSI ioctls
that are defined in the <sys/scsicmd.h> header file
and documented on the
for general information about kernel error messages,
including a list of generic device driver errors.
