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://gitlab.com/slof/slof, and the image currently in qemu is
17 built from git tag qemu-slof-20241106.
18
19- VOF (Virtual Open Firmware) is a minimalistic firmware to work with
20 -machine pseries,x-vof=on. When enabled, the firmware acts as a slim shim and
21 QEMU implements parts of the IEEE 1275 Open Firmware interface.
22
23- The PXE roms come from the iPXE project. Built with BANNER_TIME 0.
24 Sources available at http://ipxe.org. Vendor:Device ID -> ROM mapping:
25
26 8086:100e -> pxe-e1000.rom
27 8086:1209 -> pxe-eepro100.rom
28 1050:0940 -> pxe-ne2k_pci.rom
29 1022:2000 -> pxe-pcnet.rom
30 10ec:8139 -> pxe-rtl8139.rom
31 1af4:1000 -> pxe-virtio.rom
32
33- The sources for the Alpha palcode image is available from:
34 https://github.com/rth7680/qemu-palcode.git
35
36- The u-boot binary for e500 comes from the upstream denx u-boot project where
37 it was compiled using the qemu-ppce500 target.
38 A git mirror is available at: https://gitlab.com/qemu-project/u-boot.git
39 The hash used to compile the current version is: 2072e72
40
41- Skiboot (https://github.com/open-power/skiboot/) is an OPAL
42 (OpenPower Abstraction Layer) firmware for OpenPOWER systems. It can
43 run an hypervisor OS or simply a host OS on the "baremetal"
44 platform, also known as the PowerNV (Non-Virtualized) platform.
45
46- pnv-pnor.bin is a non-volatile RAM image used by PowerNV, which stores
47 NVRAM BIOS settings among other things. This image was created with the
48 following command (the ffspart tool can be found in the skiboot source tree):
49
50 ffspart -s 0x1000 -c 34 -i pnv-pnor.in -p pnv-pnor.bin
51
52 Where pnv-pnor.in contains the two lines (no leading whitespace):
53
54 NVRAM,0x01000,0x00020000,,,/dev/zero
55 VERSION,0x21000,0x00001000,,,/dev/zero
56
57 skiboot is then booted once to format the NVRAM partition.
58
59- QemuMacDrivers (https://github.com/ozbenh/QemuMacDrivers) is a project to
60 provide virtualised drivers for PPC MacOS guests.
61
62- The "edk2-*.fd.bz2" images are platform firmware binaries and matching UEFI
63 variable store templates built from the TianoCore community's EFI Development
64 Kit II project
65 <https://github.com/tianocore/tianocore.github.io/wiki/EDK-II>. The images
66 were built at git tag "edk2-stable202302". The firmware binaries bundle parts
67 of the OpenSSL project, at git tag "OpenSSL_1_1_1s" (the OpenSSL tag is a
68 function of the edk2 tag). Parts of the Berkeley SoftFloat library are
69 bundled as well, at Release 3e plus a subsequent typo fix (commit
70 b64af41c3276f97f0e181920400ee056b9c88037), as an OpenSSL dependency on 32-bit
71 ARM. Licensing information is given in "edk2-licenses.txt". The image files
72 are described by the JSON documents in the "pc-bios/descriptors" directory,
73 which conform to the "docs/interop/firmware.json" schema.
74
75- OpenSBI (https://github.com/riscv/opensbi) aims to provide an open-source
76 reference implementation of the RISC-V Supervisor Binary Interface (SBI)
77 specifications for platform-specific firmwares executing in M-mode. For all
78 supported platforms, OpenSBI provides several runtime firmware examples.
79 These example firmwares can be used to replace the legacy riscv-pk bootloader
80 and enable the use of well-known bootloaders such as U-Boot.
81 OpenSBI is distributed under the terms of the BSD 2-clause license
82 ("Simplified BSD License" or "FreeBSD License", SPDX: BSD-2-Clause). OpenSBI
83 source code also contains code reused from other projects described here:

86- npcm{7xx,8xx}_bootrom.bin is a simplified, free (Apache 2.0) boot ROM for
87 Nuvoton NPCM7xx/8xx BMC devices. It currently implements the bare minimum to
88 load, parse, initialize and run boot images stored in SPI flash, but may grow
89 more features over time as needed. The source code is available at:
90 https://github.com/google/vbootrom
91
92- ast27x0_bootrom.bin is a simplified, free (Apache 2.0) boot ROM for
93 ASPEED AST27x0 BMC SOC. It currently implements the bare minimum to
94 load, parse, initialize and run boot images stored in SPI flash, but may grow
95 more features over time as needed. The source code is available at:
96 https://github.com/google/vbootrom
97
98- hppa-firmware.img (32-bit) and hppa-firmware64.img (64-bit) are firmware
99 files for the HP-PARISC (hppa) architecture.
100 They are built form the SeaBIOS-hppa sources, which is a fork of SeaBIOS
101 adapted for hppa.
102 SeaBIOS-hppa is available at https://github.com/hdeller/seabios-hppa
