The Goal
The goal of this project was to successfully run Fedora 12 on the SheevaPlug.
Challenges
1. 512MB NAND is too small to install a regular installation of Fedora 12 on (The plug has no disk) 2. The plug does not have a BIOS
Solutions
1. In order to run Fedora 12 on the SheevaPlug I had to install the operating system on an SD card (although it can also be installed on a USB drive). 2. Since there is no BIOS to select which device gets booted, the SheevaPlug has a bootloader called U-boot. However, U-boot needed to be upgraded and configured for the SD card to be selected during the boot up process.
