The IBM Thinkpad X60s is a small light laptop with a Core Duo or Core 2 Duo processor and Intel graphics. It has no internal optical drive. You can see the specs at ThinkWiki, a wonderful resource with additional information.
First note that this laptop is available with two different processors.
- Core Duo
- This is a 32-bit processor, which is not supported by Arch Linux. Have a look at Arch Linux 32 instead.
- Core 2 Duo
- This processor can run the x86_64 (64-bit) version of Arch Linux, and this is recommended in this case. The full 4GB RAM will be available with the standard Arch x86_64 kernel.
A basic Arch Linux installation will do just fine for almost everything. Install from a USB CD drive or a USB flash drive following the instructions in the Installation guide.
It is easiest to do the initial installation with a wired ethernet connection which you can set up in the installation menu. In the base install package selection you can install the packages required for the wireless networking
