   1 - SeaBIOS (bios.bin) is the successor of pc bios.
   2   See http://www.seabios.org/ for more information.

   4 - The VGA BIOS and the Cirrus VGA BIOS come from the LGPL VGA bios
   5   project (http://www.nongnu.org/vgabios/).
   6
   7 - The PowerPC Open Hack'Ware Open Firmware Compatible BIOS is
   8   available at https://repo.or.cz/openhackware.git.
   9
  10 - OpenBIOS (http://www.openbios.org/) is a free (GPL v2) portable
  11   firmware implementation. The goal is to implement a 100% IEEE
  12   1275-1994 (referred to as Open Firmware) compliant firmware.
  13   The included images for PowerPC (for 32 and 64 bit PPC CPUs),
  14   Sparc32 (including QEMU,tcx.bin and QEMU,cgthree.bin) and Sparc64 are built
  15   from OpenBIOS SVN revision 1280.
  16
  17 - SLOF (Slimline Open Firmware) is a free IEEE 1275 Open Firmware
  18   implementation for certain IBM POWER hardware.  The sources are at
  19   https://github.com/aik/SLOF, and the image currently in qemu is
  20   built from git tag qemu-slof-20190114.
  21
  22 - sgabios (the Serial Graphics Adapter option ROM) provides a means for
  23   legacy x86 software to communicate with an attached serial console as
  24   if a video card were attached.  The master sources reside in a subversion
  25   repository at http://sgabios.googlecode.com/svn/trunk.  A git mirror is
  26   available at https://git.qemu.org/git/sgabios.git.
  27
  28 - The PXE roms come from the iPXE project. Built with BANNER_TIME 0.
  29   Sources available at http://ipxe.org.  Vendor:Device ID -> ROM mapping:

  31         8086:100e -> pxe-e1000.rom
  32         8086:1209 -> pxe-eepro100.rom
  33         1050:0940 -> pxe-ne2k_pci.rom

  36         1af4:1000 -> pxe-virtio.rom

  38 - The sources for the Alpha palcode image is available from:
  39   https://github.com/rth7680/qemu-palcode.git
  40
  41 - The u-boot binary for e500 comes from the upstream denx u-boot project where
  42   it was compiled using the qemu-ppce500 target.
  43   A git mirror is available at: https://git.qemu.org/git/u-boot.git
  44   The hash used to compile the current version is: 2072e72
  45
  46 - Skiboot (https://github.com/open-power/skiboot/) is an OPAL
  47   (OpenPower Abstraction Layer) firmware for OpenPOWER systems. It can
  48   run an hypervisor OS or simply a host OS on the "baremetal"
  49   platform, also known as the PowerNV (Non-Virtualized) platform.
  50
  51 - QemuMacDrivers (https://github.com/ozbenh/QemuMacDrivers) is a project to
  52   provide virtualised drivers for PPC MacOS guests.
  53
  54 - The "edk2-*.fd.bz2" images are platform firmware binaries and matching UEFI
  55   variable store templates built from the TianoCore community's EFI Development
  56   Kit II project
  57   <https://github.com/tianocore/tianocore.github.io/wiki/EDK-II>. The images
  58   were built at git tag "edk2-stable201905". The firmware binaries bundle parts
  59   of the OpenSSL project, at git tag "OpenSSL_1_1_1b" (the OpenSSL tag is a
  60   function of the edk2 tag). Parts of the Berkeley SoftFloat library are
  61   bundled as well, at Release 3e plus a subsequent typo fix (commit
  62   b64af41c3276f97f0e181920400ee056b9c88037), as an OpenSSL dependency on 32-bit
  63   ARM. Licensing information is given in "edk2-licenses.txt". The image files
  64   are described by the JSON documents in the "pc-bios/descriptors" directory,
  65   which conform to the "docs/interop/firmware.json" schema.
