CX(4) BSD/i386 Kernel Interfaces Manual CX(4)

NAME

cx — driver for synchronous/asynchronous Cronyx Sigma WAN adapters

SYNOPSIS

To compile this driver into the kernel, place the following line in your kernel configuration file:

device cx

Alternatively, to load the driver as a module at boot time, place the following line in loader.conf(5):

if_cx_load="YES"

Additional options:

device sppp
options NETGRAPH
options NETGRAPH_CRONYX

In /boot/device.hints:

hint.cx.0.at="isa"
hint.cx.0.port="0x240"
hint.cx.0.irq="15"
hint.cx.0.drq="7"

DESCRIPTION

The cx driver needs either sppp(4) or netgraph(4). Which one to use is determined by the NETGRAPH_CRONYX option. If this option is present in your kernel configuration file, the cx driver will be compiled with netgraph(4) support. Otherwise, it will be compiled with sppp(4) support.

The base I/O port address specified in /boot/device.hints must match the port address set by the jumpers on the board. The DMA I/O channel and interrupt request numbers are configured by software at adapter initialization. Legal values are:

Port:

0x240, 0x260, 0x280, 0x300, 0x320, 0x380

IRQ:

3, 5, 7, 10, 11, 12, 15

DMA:

5, 6, 7

The cx driver supports autodetection. As for all non-PNP hardware, using autodetection could lead to some potential problems with other devices during the hardware detection process. It is always better to specify hardware resources manually.

Refer to sconfig(8) for information about the cx adapter configuration.

HARDWARE

The cx driver supports the following cards:

Cronyx Sigma-22, Sigma-24

Cronyx Sigma-100

Cronyx Sigma-400, Sigma-401, Sigma-404, Sigma-410, Sigma-440

Cronyx Sigma-500

HISTORY

The cx driver was updated in FreeBSD 5.2 and FreeBSD 4.10. In most of the previous versions of FreeBSD the cx driver is out of date. The cx driver for previous versions of FreeBSD is available from http://www.cronyx.ru/.
