README

- The PC BIOS comes from the Bochs project (http://bochs.sourceforge.net/).

- The VGA BIOS and the Cirrus VGA BIOS come from the LGPL VGA bios
  project (http://www.nongnu.org/vgabios/).

- The PowerPC Open Hack'Ware Open Firmware Compatible BIOS is
  available at http://perso.magic.fr/l_indien/OpenHackWare/index.htm.

- video.x is a PowerMac NDRV compatible driver for a VGA frame
  buffer. It comes from the Mac-on-Linux project
  (http://www.maconlinux.org/).

- OpenBIOS (http://www.openbios.org/) is a free (GPL v2) portable
  firmware implementation. The goal is to implement a 100% IEEE
  1275-1994 (referred to as Open Firmware) compliant firmware.
  The included images for Sparc32, Sparc64 and PowerPC (for 32 and 64 bit
  PPC CPUs) are built from OpenBIOS SVN revision 569.

- The PXE roms come from Rom-o-Matic etherboot 5.4.2.
