Adding Hardware to the AAO has spare parts.

Plug in stuff

USB Hard disks or Sticks can be easily added to the AAO and the BIOS supports booting from it.

A way to expand the AAO is using the SD card slot on the lower left corner of the AAO, it is marked with the text Storage Extension. Drawbacks are not boot from there and AAO Linpus is configured in a way that it automatically writes stuff there.

The AAO service manual can be obtained from the Internet showing how to open the AAO.

The internal SSD has a standard ZIF 40 pin connector. An update with a SSD preferably having the same form factor (or a hard disk) is simply possible. The only hurdle is that ZIF drives no not common.


Check on how to open the AAO.


Just take care to remove the flat cable to the track pad before removing the top cover.

Solid state media and lifetime concerns

A lot of discussion is going on regarding installation to solid state media as the internal SSD, USB sticks and Flash cards (as MMC/SD cards). Luckily, there is also a lot of development going on and many things once written might be outdated and no more true.

Solid state media have limited life time due to the limited numbers of write cycles. Mostly it is forgotten that also mechanical hard disks have a limited life time too. The installation of Linux to a MMC/SD card is not critical, since it worked well many years until I decided to install bigger SSD.

However, to not jeopardize lifetime of solid state media, avoid frequent writes to those media, therefore avoid using swap space on Flash media. Swap has been invented to expand RAM to Harddisk space. Instead of using swap on solid state media as a hard disk, it is probably better to upgrade the RAM.

Installing Gentoo on a SDcard and using the internal SSD just for boot (=read only) is a good concept regarding lifetime of the solid state media. However, the original swap partition of the internal SSD could be kept.

The SDHC card to be used can be 32GByte with the speed of up to 20MByte/s read and up to 8 Mbyte/s write. For SD cards see:
