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.conf5:

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 ifconfig 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 ifconfig 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 ifconfig 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 ifconfig adapter configuration.

HARDWARE

The ifconfig 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
• Cronyx Sigma-703
• Cronyx Sigma-800, Sigma-801, Sigma-810, Sigma-840

HISTORY

The ifconfig driver was updated in Fx 5.2 and Fx 4.10 . In most of the previous versions of Fx the ifconfig driver is out of date. The ifconfig driver for previous versions of Fx is available from www.cronyx.ru
