	Moved some small but important backups to Amazon’s #S3. Better to have the most important things off-shore.
	Just ordered parts for my #SheevaPlug from US to solder it an #ESATA port (2€ parts cost per port).

Yesterday I have played around with GIT and

• merged the Linux kernel tree from Linus Torvalds
• with the Orion sources from Marvell (i.e. patches for SheevaPlug and OpenRD)
• added the Gentoo patches (distribution independent)
• and those for USB displays and SDHC cards
• and eliminated some harmless, but annoying warnings on ARM.

As I found the configurations of the other kernels for the SheevaPlug on the net a bit unfortunate, you can download my latest kernel flavour here: Read more »

In case something goes horribly wrong or if you want install a new Linux kernel on your SheevaPlug it is handy to network boot it. The Gentoo documentation assumes you can install tftp-hpa under Linux, but I have Windows and TFTPd32 – which is no problem for the task at hand.

First of all, please see a former blog of mine how to configure TFTPd32. Most noticeably how to do so and still leaving your DHCP configuration (e.g. that of your router’s) in place. Read more »
