# ASUS Eee PC 1201n

This page contains instructions, tips, pointers, and links for installing and configuring Arch Linux on the ASUS EEE 1201n PC.

Aside from incompatability with cpufrequtils, the eeepc 1201NL is very similar to this model, and most of the tips on that page apply to this model as well.

## Installing Wireless

The default eee 1201n carries a Realtek 8191 Wireless card, despite what lspci reports that the computer has a Realtek 8171 (rev 10). The wireless driver is included in linux 3 kernel and should work out of the box.

## cpufrequtils

The Intel Atom 330 does not support cpufrequtils in any reasonable way, so it is not recommended that you use cpufrequtils. You can disable it in /etc/laptop-mode/conf.d/cpufreq.conf:

    CONTROL_CPU_FREQUENCY=0

Because the Atom uses so little power anyway, controlling the FSB using the "SuperHybrid Engine" should provide significant gain in battery life without the need for CPU scaling.
