subordinate_bus - set its default value [solved]

Edd · June 29, 2005

My wireless connection is now running great, but everytime I boot up linux I have to run the following command:

setpci -s 0:14.4 subordinate_bus=03

I have to do this because it keeps defaulting to 02 which stops mandrake recognising my wireless card. Where can I change the default value of the subordinate_bus so that it doesn't change on reboot?

Thanks a lot for all your help so far :)

What kind of wireless card do you have? Is it a PCI, or PCMCIA for laptop?

I found a post, although it mentions the following:

The last step to getting the wireless card to work on boot was to insert the following code at the end of /etc/init.d/pcmcia

setpci -s 0:a.0 SUBORDINATE_BUS=0A cardctl eject 0 cardctl insert 0

If you have a PCMCIA wireless card, you could add your line to the bottom of /etc/init.d/pcmcia, which you quoted above as being:

setpci -s 0:14.4 subordinate_bus=03

Does that help at all?

I tried pasting the code right at the very bottom but nothing. I tried near the bottom but in difference places but still nothing. Can you see an "obvious" place to put it? Thanks :)

ianw1974 · June 30, 2005

From the search I did, the text that I copied over, mentioned pasting to the end of the file.

I've just found another post, and I think you would need to put it in /etc/rc.local

Sorry for the incorrect information before! Hope it works this time :P

Well I tried putting it in the other file you mentioned. but still nothing :( Here is the contents of rc.local:

I've tried it here ---->setpci -s 0:14.4 subordinate_bus=03
touch /var/lock/subsys/local
and here ---->setpci -s 0:14.4 subordinate_bus=03

Notice where I have tried it at the bottom. I can't see anywhere else to put it, I'm worried if I get too click happy I'll stop it working, so do you know where abouts would be a good place to put the line? Thanks for all your help so far :)

ianw1974 · June 30, 2005

I'm honestly not sure where else that I could think of to put it. You could try a google on "subordinate_bus" and see what results come back.

I'm sure there is a file somewhere you can add this too, and it'd work. I've just no idea what the startup files are for making such settings! A brief search I did threw up the results I posted so far.

Edd · June 30, 2005

I had a look on google as you said (god knows why I never before). I found some information, it wasn't quite right, I combined it with what you said and i have the solution! So, to set the subordinate_bus default, do the following:

Add these lines of code to the top of /etc/init.d/pcmcia/

setpci -s 0:a.0 SUBORDINATE_BUS=0A
cardctl eject 0
cardctl insert 0

If the setpci line isn't as you want, just change the settings, I had to change mine to "setpci -s 0:14.4 SUBORDINATE_BUS=03"

Thanks for your help Ian :) Maybe this would be worth documenting somewhere?

Cool, we got there in the end :P glad its sorted.
