     isapnp - introduction to ISA Plug-and-Play support

SYNOPSIS    [Toc]    [Back]

     isapnp0 at isa?

DESCRIPTION    [Toc]    [Back]

     An isapnp bus can be configured for each supported ISA  bus.

     OpenBSD provides machine-independent bus support and drivers
for ISA
     Plug-and-Play (isapnp) autoconfiguration  of  PnP-compatible
devices on an
     ISA bus.

SUPPORTED DEVICES    [Toc]    [Back]

     OpenBSD  includes machine-independent ISAPNP drivers, sorted
by function
     and driver name:

HISTORY    [Toc]    [Back]

     The isapnp driver appeared in NetBSD 1.3.

CAVEATS    [Toc]    [Back]

     From time to time an isapnp device will be found  which  the
kernel does
     not  recognize.  The kernel matches isapnp devices to device
drivers based
     on identifiers which each  device  provides.   For  example,
this device:

     joy0  at isapnp0 <Creative SB16 PnP, CTL7001, PNPB02F, Game>
port 0x200/8

     This joystick calls itself by the two names ``CTL7001''  and
``PNPB02F''.
     The latter is a standard name (which the kernel automatically recognizes),
 but ``CTL7001''  is  a  vendor-specific  name  which
needs to be added
     to  a  table.   Unfortunately,  some  devices advertise only
their vendor-specific
 name; for instance:

     isapnp0: <PnP Sound Chip, @P@1001, , > port 0x200/8 not configured

     Testing  will  show that this device is actually a joystick.
To resolve
     the issue, the actual name ``@P@1001'' has to be entered into the
     database found in /sys/dev/isa/pnpdevs and a new kernel must
be built.
     Then the device will probe like this:

     joy0 at isapnp0 <PnP Sound Chip, @P@1001, , > port 0x200/8
