Manually changing IRQ/reconfiguring network?
I have Debian 3.0 installed on an HP Pavillion N5425 laptop, and after
considerable modifications it is (mostly) working.
Often, however, it seems that I "fix one thing, break two others".
I have two current problems, one of which is probably in the documentation
somewhere but I just can't find it, the other is a bit more esoteric:
1) Reconfiguring network: I have somehow managed to break the network
configuration, so that I no longer seem to be able to get an IP address. The
card is there, the card is up, but dhclient eth0 doesn't get me any error
messages. I am not sure how to troubleshoot this problem, and also not sure
what caused it. I expect it was something to do with my recompiling the
kernel; however, when I booted the previous kernel (where the networking
used to work fine), the same symptoms persist.
Question: what is the best way to reconfigure the network from scratch
(i.e., wipe out the current installation and start again)?? I would much
rather do it using the installation scripts where available, instead of
manually tweaking configuration files. I looked through the various
documentation, but all I could find was instructions for using the Progeny
2) Forcing different IRQ for USB: From what I can gather, the USB controller
gets assigned IRQ 9 by default in Linux; unfortunately, this is not correct,
due to a buggy bios, and though the controller will be identified, no USB
devices will work. The USB controller has to be manually forced to use
IRQ11. Where would I make this change??
Thanks in advance,
