What is "pegasos"

Pegasos is a MicroATX motherboard powered by a PowerPC 750CXe or PowerPC 7447 microprocessor, featuring three PCI slots, one AGP slot, two Ethernet ports (10/100/1000 & 10/100), USB, DDR, AC'97 sound, and FireWire. Like the PowerPC Macintosh counterparts, it boots via Open Firmware.

For hard disk drive booting the Open Firmware implementation called SmartFirmware requires an RDB boot partition that contains either an affs1 or ext2 partition. Note that any changes to the ext2 on-disc format may prevent booting. It is, however possible to add some ext3 features so long as the volume can still be recognized as ext2.

The Pegasos was sold by Genesi USA, Inc., and designed by their research and design partner bplan GmbH based in Frankfurt, Germany.

There are two versions of the system: The Pegasos I and the Pegasos II.
