.Nd Advansys ISA/VL/EISA/PCI 8bit SCSI Host adapter driver
.Sh SYNOPSIS
For one or more ISA or VL cards:
.Cd controller isa0
.Cd controller "adv0 at isa? port ? cam irq ? drq ?"
.Pp
For one or more EISA cards:
.Cd controller eisa0
.Cd controller adv0
.Pp
For one or more PCI cards:
.Cd controller pci0
.Cd controller adv0
.Pp
For one or more SCSI busses:
.Cd controller scbus0 at adv0
.Sh DESCRIPTION
This driver provides access to the 8bit
.Tn SCSI
bus connected to the Advanced Systems Products, Inc.
.Tn ASC900 ,
.Tn ASC1000 ,
.Tn ASC1090 ,
.Tn ASC1200 ,
.Tn ASC3050 ,
and
.Tn ASC3150
host adapter chips.
The following tables list the AdvanSys products using these chips,
their bus attachment type, maximum sync rate, and the maximum number of
commands that can be handled by the adapter concurrently.

This board has been shipped by HP with the 4020i CD-R drive.
The board has no BIOS so it cannot control a boot device, but
it can control any secondary SCSI device.

For ISA or Vesa Local Bus adapters, one kernel config entry is required
for every card to be attached by the system. Specific values for the port
address, irq, and drq may be specified. If wildcard values are used, the
driver will query the device for its current settings and use those. If
the port address is a wildcard, the driver consults an internal table of
possible port address locations and attaches to the first unattached card
it finds. The possible port addresses for these card are 0x110, 0x130,
0x150, 0x190, 0x210, 0x230, 0x250, and 0x330.
.Pp
Per target configuration performed in the
.Tn AdvanceWare
menu, which is accessible at boot,
is honored by this driver.
This includes synchronous/asynchronous transfers,
maximum synchronous negotiation rate, disconnection, tagged queueing,
and the host adapter's SCSI ID.
The global setting for the maximum number of tagged transactions allowed
per target is not honored as the CAM SCSI system will automatically determine
the maximum number of tags a device can receive as well as guarantee fair
resource allocation among devices.
