I was reding the Phoronix review of the ASUS P5E3 Deluxe motherboard, coming with an embedded linux you can choose to run from a boot prompt. This is quite cool, and Asus plans to publish updated of the embedded system. It will sadly require to run Windows on the hard disk to update it.
When will this stop? This is a wide-spread situation: plenty of Linux server applications require windows to run the client or administration tools.
