+.Sh SYNOPSIS
+.Cd device isa
+.Cd device cm
+.Sh DESCRIPTION
+The
+.Nm
+driver provides support for the
+.Tn Arcnet
+.Tn ISA
+network adapters.
+This driver supports the following card models:
+.Pp
+.Bl -item -compact
+.It
+SMC90c26
+.It
+SMC90c56
+.It
+SMC90c66 in '56 compatibility mode.
+.El
+.Pp
+The
+.Nm
+driver also has quirks preset in the
+.Xr device.hints 5
+file for card detection.
+.Sh IMPLEMENTATION NOTES
+When the
+.Va NOARP
+flag is set on the
+.Nm
+interface,
+it does not employ the address resolution protocol described in
+.Xr arp 4
+to dynamically map between Internet and Ethernet addresses on
+the local network.
+Instead it uses the least significant 8 bits of the
+.Tn IP
+address as the hardware address
+like described in
+.Tn RFC
+1051
+and
+.Tn RFC
+1201.
+.Pp
+With the
+.Dv IFF_LINK0
+flag cleared
+.Tn IP/ARP/RARP
+encoding is done according to
+.Tn RFC
+1201
+that is, with Packet Header Definition Standard header and packet type
+212 / 213.
+The
+.Tn MTU
+is normally 1500.
+The
+.Dv IFF_LINK0
+flag is cleared by default.
+.Pp
+With the
+.Dv IFF_LINK0
+flag set,
+.Tn IP
+and
+.Tn ARP
+encoding is done according to the deprecated
+.Tn RFC
+1051 encoding, that is with simple header, packet type 240 / 241,
+and the
+.Tn MTU
+is 507.
+.Pp
+When switching between the two modes, use
+.Dl ifconfig interfacename down up
+to switch the
+.Tn MTU .
+.Sh ERRORS
+The following driver specific error messages
+may be reported:
+.Bl -tag -width Er
+.It Bq Er ENOENT
+May be returned if the device cannot allocate a port,
+memory resource, or IRQ with the given resource ID.
+.It Bq Er EINVAL
+May be returned if the device is marked as down and is
+still running.
+This error may also be returned if the device is marked as up
+but is not running.

+.Sh NAME

+.Sh SYNOPSIS
+.Cd device scbus
+.Cd device esp
+.Sh DESCRIPTION
+The
+.Nm
+driver provides support for the
+.Tn Qlogic
+FAS216 and FAS408
+.Tn SCSI
+controller chips found in a wide variety of systems and peripheral boards.
+This includes the
+.Tn Qlogic
+.Tn SCSI
+cards found in most
+.Tn Sun
+.Tn Ultra 1e
+and
+.Tn Ultra 2
+machines.
+.Pp
+For
+.Tn Qlogic
+.Tn PCI
+.Tn SCSI
+host adapters, the
+.Xr isp 4
+driver should be used in place of the
+.Nm
+driver.
+.Sh IMPLEMENTATION NOTES
+During the boot sequence, the
+.Nm
+driver
+searches the linked list for LUN info by LUN ID.
+At this point the driver will attach on that instance,
+and then attempt to attach every sub-device.
+.Pp
+There are at least 4 variations of the
+configuration 3 register.
+A second config register must be loaded to inquire the chip revision,
+otherwise the
+.Fn ncr53c9x_reset
+function will not set the defaults correctly.
+.Pp
+The drive attach routine attempts to set the appropriate
+bit to put the chip into Fast
+.Tn SCSI
+mode so that it does not
+have to be figured out each time.
+This will then be stored in the
+.Tn NCR
+registers for later use.
+.Pp
+The
+.Nm
+driver makes use of the
+.Tn LSI
+64854
+.Tn DMA
+engine which contains three independent
+channels designed to interface with
+an NCR539X
+.Tn SCSI
+controller;
+an AM7990 Ethernet controller;
+and certain types of parallel port hardware.
+As such this driver may eventually replace the
+.Xr amd 4
+driver for network hardware.
+.Pp
+.Sh ERRORS
+The following driver specific error messages
+may be reported:
+.Bl -tag -width Er
+.It Bq Er EINVAL
+May be returned if the driver cannot detach or reset
+the state and/or bus.
+.It Bq Er ENOMEM
+Might be returned if the driver cannot allocate
+parent
+.Tn DMA
+tag, or if the device is out of memory.
+.It Bq Er ENXIO
+May be returned if the driver cannot map
+.Tn DMA
+registers.
+This error may also be returned if the driver is
+unable to map the
+.Tn SCSI
+core registers.

+.Sh AUTHORS
+This manual page was written by

+instead of porting the original from

+.Sh BUGS
+The
+.Nm
+driver includes the sbus front-end but lacks the
+.Tn PCI
+front-end.
+Thus it can only support the
+.Tn FEPS/FAS366
+.Tn SCSI
+found in
+.Tn Sun
+.Tn Ultra 1e
+and
+.Tn Ultra 2
+machines at this time.
+.Pp
+This driver should eventually replace the
+.Xr amd 4
+driver, but that requires porting the
+.Tn PCI
+front-end mentioned above.

+The

+is an eight port
