1- SeaBIOS (bios.bin) is the successor of pc bios.
2  See http://www.seabios.org/ for more information.
3
4- The VGA BIOS and the Cirrus VGA BIOS come from the LGPL VGA bios
5  project (http://www.nongnu.org/vgabios/).
6
7- OpenBIOS (http://www.openbios.org/) is a free (GPL v2) portable
8  firmware implementation. The goal is to implement a 100% IEEE
9  1275-1994 (referred to as Open Firmware) compliant firmware.
10  The included images for PowerPC (for 32 and 64 bit PPC CPUs),
11  Sparc32 (including QEMU,tcx.bin and QEMU,cgthree.bin) and Sparc64 are built
12  from OpenBIOS SVN revision 1280.
13
14- SLOF (Slimline Open Firmware) is a free IEEE 1275 Open Firmware
15  implementation for certain IBM POWER hardware.  The sources are at
16  https://github.com/aik/SLOF, and the image currently in qemu is
17  built from git tag qemu-slof-20200717.
18
19- sgabios (the Serial Graphics Adapter option ROM) provides a means for
20  legacy x86 software to communicate with an attached serial console as
21  if a video card were attached.  The master sources reside in a subversion
22  repository at http://sgabios.googlecode.com/svn/trunk.  A git mirror is
23  available at https://git.qemu.org/git/sgabios.git.
24
25- The PXE roms come from the iPXE project. Built with BANNER_TIME 0.
26  Sources available at http://ipxe.org.  Vendor:Device ID -> ROM mapping:
27
28	8086:100e -> pxe-e1000.rom
29	8086:1209 -> pxe-eepro100.rom
30	1050:0940 -> pxe-ne2k_pci.rom
31	1022:2000 -> pxe-pcnet.rom
32	10ec:8139 -> pxe-rtl8139.rom
33	1af4:1000 -> pxe-virtio.rom
34
35- The sources for the Alpha palcode image is available from:
36  https://github.com/rth7680/qemu-palcode.git
37
38- The u-boot binary for e500 comes from the upstream denx u-boot project where
39  it was compiled using the qemu-ppce500 target.
40  A git mirror is available at: https://git.qemu.org/git/u-boot.git
41  The hash used to compile the current version is: 2072e72
42
43- Skiboot (https://github.com/open-power/skiboot/) is an OPAL
44  (OpenPower Abstraction Layer) firmware for OpenPOWER systems. It can
45  run an hypervisor OS or simply a host OS on the "baremetal"
46  platform, also known as the PowerNV (Non-Virtualized) platform.
47
48- QemuMacDrivers (https://github.com/ozbenh/QemuMacDrivers) is a project to
49  provide virtualised drivers for PPC MacOS guests.
50
51- The "edk2-*.fd.bz2" images are platform firmware binaries and matching UEFI
52  variable store templates built from the TianoCore community's EFI Development
53  Kit II project
54  <https://github.com/tianocore/tianocore.github.io/wiki/EDK-II>. The images
55  were built at git tag "edk2-stable202008". The firmware binaries bundle parts
56  of the OpenSSL project, at git tag "OpenSSL_1_1_1g" (the OpenSSL tag is a
57  function of the edk2 tag). Parts of the Berkeley SoftFloat library are
58  bundled as well, at Release 3e plus a subsequent typo fix (commit
59  b64af41c3276f97f0e181920400ee056b9c88037), as an OpenSSL dependency on 32-bit
60  ARM. Licensing information is given in "edk2-licenses.txt". The image files
61  are described by the JSON documents in the "pc-bios/descriptors" directory,
62  which conform to the "docs/interop/firmware.json" schema.
63
64- OpenSBI (https://github.com/riscv/opensbi) aims to provide an open-source
65  reference implementation of the RISC-V Supervisor Binary Interface (SBI)
66  specifications for platform-specific firmwares executing in M-mode. For all
67  supported platforms, OpenSBI provides several runtime firmware examples.
68  These example firmwares can be used to replace the legacy riscv-pk bootloader
69  and enable the use of well-known bootloaders such as U-Boot.
