More U810 thoughts

The U810/U1010 has pads for two Mini PCI-e slots underneath the bottom cover but most only have one in place. Looking at the dissection photos on the Internet it seems that there are no chips or support components missing - just the socket - so it should be feasible to solder a new one in - the pads are easy to reach and the pitch isn't too small.

Getting said socket isn't too easy though - RS Components has them scheduled for October. It looks like the exploding demand for eee PC's and the like has drained the world's supply of Mini PCI-e sonnectors - later eee's also come with only one of two possible sockets in place.

The other alternative, in the same vein as many eee PC mods, is to tack a USB socket in place of the PCI-e connector (using the USB lines that are available on the PCI-e pads). That would be a nice place to put a USB key as an SSD or maybe a TV tuner... Now I just need to find a nice point I can source 5V from - with all the eee PC hacking out there I'm surprised there hasn't been a bit of U810 activity in this area.

I have also got a Compact Flash to 1.8" ZIF convertor (off ebay) to try out using CF as an SSD alternative - slower but actually designed for low power consumption so may well benefit run-time. The first couple of CF cards I tried weren't recognised by the BIOS. To test that it wasn't the convertor I got hold of an Icy Dock USB caddy from Scan - obviously designed for displaced iPod drives! The cards worked fine in this mode - I suspect it is because most CF cards claim to be removable ATA devices and some BIOS's will only accept fixed devices. Transcend is one of the few manufacturers whose CF cards switch to "Fixed" mode when operating in IDE, rather than CF, mode so I'll get hold of one and try it. Sandisk, Kingston and Intuix are brands which do not - from experience. Under Linux you can use hdparm -i on a CF card to find out if it is Fixed or Removable mode.

Elisa 5.3 seems to be an awkward release to get up and running - I had to edit the source code (to bypass a "not implemented yet" error) to even get the main screen up so I'll park that for now until a later release.
