Some notes from my experiences with the alix 2d13 hardware, the information may be outdated already, but might be useful as reference anyway.

I just realized my desktop computer lacks a serial port … the mainboards manual:
The COMA header can provide one serial port via an optional COM port cable. For purchasing the optional COM port cable, please contact the local dealer.
and I borrowed my pl2303-usb-serial-cable to a friend … But my notebook still got serial.

The alix2d.13 has a battery powered clock, but the clock is not that stable. Therefore we'll install ntpd, keeping locks sync since 1970.
aptitude install openntpd

Note: I already updated to 2.6.32-deadlock due to some hostapd wifi issues. You can not run PAE enabled kernels on this plattform, and it is very hard to compile xtable-addons for the kernels provided by roberttalks.com

My flash card died after less than 6hours, it survived exactly the install.
Therefore I decided to attach a 2.5” ide hdd to the alix board.
Getting the disk was easy, getting a 44pin ata cable in the required length was not.
The disk does not fit into the case, therefore it is mounted on the back.
The disk is attached as slave, and you can not run disk & flash in parallel.
But, now I have 160G storeage on this device, and do not have to care about flash media write cycles and random deaths.

Markus, I've got a 2.5 HDD fitted inside an AliX enclosure, it is possible.

Hi,
can you send me a picture of your alix internals & metrics where to place the hdd, so others can benefit?
I'd make a picture of my piggy back hdd setup too ;)
Hey!,
Are you running debian on a full read-write filesystem? I thought flash based media wares out after 10000 writes ?
