ALIX system boards were manufacturered and sold by PC Engines. They utilise the x86-based AMD Geode SC1100 CPU (fast 486 core). The building and installation procedure is very similar to newer Alix boards except some small differences. See referred pages for more info.
There are no pre-built images for the WRAP boards available at http://downloads.openwrt.org/. The generic x86 ones will not include the appropriate drivers (e.g. wireless, LED support). Building your own image and specifying the build profile below will ensure the appropriate drivers are all included in the image.
Build profile should be:
Under the most recent Backfire repository, under x86_generic, find the image named "openwrt-x86-generic-combined-ext2.img.gz". After flashing the OpenWrt image, follow these guides to install missing packages:
opkg update opkg install kmod-leds-wrap
Instead of ext2 image mentioned above, you can use squasfs or jffs2 filesystems, too. Trunk images are also available.
I just installed OpenWRT on a WRAP 2c using 12.09/attitude_adjustment. I started with Attitude Adjustment repository and placed openwrt-x86-generic-combined-ext4.img.gz on a CF. It boots with DMA enabled, which doesn't work, so you have to have several minutes of patience and perhaps hit ctrl-C several times when it stops just after
