My laptop is working!
After a lot of work my shiny new IBM R40e is up and running with almost working ACPI, internal network adapter and a 3Com 54g wireless PCMCIA card, all on Gentoo Linux.
A Mini HOWTO:
- Get an old PCMCIA card for the installation as the internal network adapter is not supported by the Live-CD
- I choose the Gentoo Stable kernel which is working great
- Do not enable PCMCIA in the kernel, emerge the pcmcia-cs package instead for continued setting up of the system.
the network card driver
from Broadcom, the card is a BCM-5700. Compile it and put it in
modprobe bcm-5700Add it to /etc/modules.autoload/kernel-2.4 if needed
- Get the ISL driver for the 3Com card. Follow the instructions closely, but patch the gs-sources kernel instead. I removed the pcmcia-cs package before compiling the kernel as it provides its own cardbus implementation. Supposedly only the card drivers can be compiled, but I didn’t try that.
- Emerge the wireless-tools package.
iwconfigis your friend.
- ACPI is somewhat unstable, the battery information comes and goes in a undetermistic way.
- The modem is supported by the HSF driver but that in turn does not support preemptible kernels. Choose whatever you want
I’ll probably update this as I learn more. This is posted over wireless by the way :)
