Hi guys,

I am trying to set my wifi to work under Slackware 12.0. Because my Slackware had problems while starting I had to install it again and add acpi=off to the kernel. Then I was able to use the system. But now when I want to set the battery control I do not have the acpi. But still if I try to compile the kernel with acpi once again the system may not start.

What should I do ?

Thank you for any help.

you could tell us what your problem is exactly.

- Are you trying to get acpi/battery support working?
- Are you trying to get your wireless network card working?

also, give some details on your hardware, and for acpi, try to describe more precisely what doesn't work (give relevant parts of dmesg output, /var/log/syslog and /var/log/messages)

Take a look at this..

Hope it helps,

Hi,

I would like to enable the card and the acpi/battery. Yesterday I have copied the firmware for slack 12 to /lib/firmware. When I started the system the card has been detected, but then my eth0(cable card) couldn't be set. When I removed the /lib/firmware/ipw*** the eth0 could be set easily.
I am working on my laptop - >Acer Travelmate 4100,

try running these commands:
and see if you can use the battery monitor in KDE

For the network card: how does loading the firmware for your wireless card affect bringing up eth0?
could you post ifconfig -a, now, and after you boot with the firmware in /lib/firmware?

Hi,

I would like to say that I compile the kernel with acpi=off. Becase without it my Slack couldn't start.

can't use the KDE support as the the message tells that I do not have the acpi or apm installed.

After installing the firmware:

I understand you have build a custom kernel, maybe there's a problem in your kernel configuration.
I've had kernels not working just because I forgot to enable one stupid option.

Did you use this kernel config before?
Try to boot with the generic kernel provided by pat, and see if that works. (don't forget to make a initrd for your root partition)
