ams is a PCSCSI 2.3.0
boot-time loadable driver (BTLD)
for any of these Advanced Micro Devices host adapter cards:
PCSCSI
(part number Am53C974)
PCSCSI II
(part number Am53C974A)
PCnet*-SCSI
(part number Am79C970)
Refer to the
Compatible Hardware Web Pages.
to determine the support status of your host adapter, or
contact your system supplier.
Configuring the ams driver
You can configure the ams driver using entries in
/etc/conf/cf.d/mdevice and /etc/conf/sdevice.d/ams.
See
mdevice(F)
and
sdevice(F).
Changes to these files
take effect once you relink the using
link_unix(ADM)
and reboot the system.
Configure ams driver-specific characteristics
by editing the /etc/conf/pack.d/ams/space.c file.
Boot time configuration of SCSI
Use the
bootstring(HW)
parameters to override
the default hardware configuration information.
Of special interest are the adapter= parameter
that specifies information for
the host adapter card
that plugs into or is part of the motherboard,
and the periph= parameter
that specifies information about the host adapter
being used by one of the generic peripheral interfaces
(Sdsk, Srom, or Stp).
ioctl commands
The ams driver
supports all standard SCSI ioctls
that are defined in the <sys/scsicmd.h> header file
and documented on the
scsi(HW)
manual page.
Diagnostics
See
messages(M)
for general information about kernel error messages,
including a list of generic device driver errors.
