|
The

|
.Nm HP9000/300
|
||||||

|
driver and is

||||||
|
.Ud
|
||||||
|
.Sh BUGS
|
||||||
|
Data loss is possible on busy systems with baud rates greater than 300.
|
||||||
|
The
|
||||||
|
.Nm com
|
||||||
|
driver is slow, buggy, and not properly tested.
|
||||||
|
.Pp
|
||||||
|
The name of this driver and the constants which define the locations
|
||||||
|
of the various seiral ports are holdovers from
|

.Nm DOS .

|

|
As usual, you get what you pay for; cheap NS16550 clones
|
||||||
|
generally don't work.

|
||||||
|
.Sh DESCRIPTION
|
||||||
|
The
|
||||||
|
.Nm npx
|
||||||
|
driver enables the use of the system's Numeric Processing Extension
|
||||||
|
coprocessor,
|
||||||
|
if one is present. Numeric processing extensions are present in
|
||||||
|
systems with
|
||||||
|
.Nm 486DX
|
||||||
|
CPUs and in systems with
|
||||||
|
.Nm 387
|
||||||
|
or
|
||||||
|
.Nm 487SX
|
||||||
|
coprocessors. The
|
||||||
|
.Nm npx
|
||||||
|
driver is required for proper system functioning regardless
|
||||||
|
of whether or not a NPX is present.
|
||||||
|
.Pp
|
||||||
|
If there is no NPX present in the system, the "MATH_EMULATE"
|
||||||
|
option must be defined in the kernel configuration file.
|
||||||
|
It will provide support for the instructions normally executed
|
||||||
|
by the NPX. If there is no NPX in the system and the kernel
|
||||||
|
is not built with math emulation, the system will not boot.
|
||||||
|
.Sh CAVEATS
|
||||||
|
The emulator is much slower than the NPX coprocessor.
|
||||||
|
This will result in poor floating-point math performance
|
||||||
|
if the emulator must be used.
|
||||||
|
.Sh BUGS
|
||||||
|
There are lots of them, especially on cheap motherboards. In particular,
|
||||||
|
some motherboards do not have the interrupt lines from the NPX to
|
||||||
|
the CPU wired properly. If this is the case, the emulator must be used
|
||||||
|
if consistent system operation is desired.
|
||||||
|
.Pp
|
||||||
|
Emulation of the transcendental functions instructions is incorrect.
|
||||||
|
Emulation of other instructions is suspect.

|

The

|

|
The

|
driver is derived from the

|
.Sh BUGS
|
||||||
|
Data loss is not near as likely on busy systems as they are with the
|
||||||
|
.Xr com 4
|
||||||
|
driver but they still can occur at very high baud rates on slow systems.
|
||||||
|
.Pp
|
||||||
|
The constants which define the locations
|
||||||
|
of the various seiral ports are holdovers from
|

|
.Nm DOS .
|
||||||
|
.Pp
|
||||||
|
As usual, you get what you pay for; cheap NS16550 clones
|
||||||
|
generally don't work.
