irq complication
hi,

i looked around already and had no luck finding anything.

Im trying ot install a wpc11v3 linksys wireless card, and i have been for about a week now. Smilie Im near certain i have figured out my problem. When i plug in my card while knoppix is running, it crashes. When i plug it into the laptop and boot up, it loads the card and then crashes. Theres no way to run iwconfig or anything because my card crashes the system. I have to find a way to get the card to sit in the laptop without any crashing right. So im near certain it is a IRQ conflict between my PCI and another device. How can i configure my irq's running knoppix. knoppix is installed to my harddrive so i have no option to use any cheatcodes. everything i read pertains to cheatcodes and whatnot, and i have researched and i cant find any problems like this with IRQ's.

Im using a toshiba satellite 2540cds laptop. i checked the bios and there is no IRQ option in there. Also during hte boot option i see something lke irq error pci=irq something like that im not certain. I'll have to double check that.

cnw

CNW(4)							   BSD Kernel Interfaces Manual 						    CNW(4)

NAME

     cnw -- Netwave AirSurfer wireless network driver

SYNOPSIS

     cnw*     at pcmcia? function ?

DESCRIPTION

     The cnw interface provides access to a theoretical 1 Mb/s wireless Ethernet network based on the Netwave AirSurfer Wireless LAN (formerly
     known as the Xircom Netwave Wireless LAN).

     Note that the driver does not support newer devices such as the Netwave AirSurfer ``Plus'', or the BayStack 650/660.  These devices are sup-
     ported by the awi(4) driver.

     Netwave devices are not compatible with IEEE 802.11 wireless networks.  Also note that there are Netwave devices with different wireless fre-
     quency, depending on the radio band plan in each country.

     The card uses 36K of I/O memory mapped to the card.  You may need to increase memory space available to the PCMCIA controller.  See pcmcia(4)
     for details.

     In use, the cards appear to achieve up to a 420Kb/s transfer rate, though a transfer rate between 250Kb/s and 350Kb/s is typical.

     The card operates in the 2.4GHz frequency range and is subject to interference from microwaves, IEEE 802.11 wireless network devices, as well
     as earth.	For example, it seems that IEEE 802.11 channel 14 conflicts with Netwave (US frequency).  They interfere with each other if they
     are both operated in the same geographic region, causing weird packet loss.  You may be able to avoid the interference with IEEE 802.11
     devices, by changing the IEEE 802.11 channel.

HARDWARE

     Cards supported by the cnw driver include:

	   Xircom CreditCard Netwave

	   NetWave AirSurfer

DIAGNOSTICS

     cnw0: can't map memory  Indicates that the driver was not able to allocate enough PCMCIA bus address space into which to map the device.  See
     pcmcia(4) and increase memory available to the PCMCIA controller.
