- SeaBIOS (bios.bin) is the successor of pc bios.
See http://www.seabios.org/ for more information.
- 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 https://repo.or.cz/openhackware.git.
- 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 PowerPC (for 32 and 64 bit PPC CPUs),
Sparc32 (including QEMU,tcx.bin and QEMU,cgthree.bin) and Sparc64 are built
from OpenBIOS SVN revision 1280.
- SLOF (Slimline Open Firmware) is a free IEEE 1275 Open Firmware
implementation for certain IBM POWER hardware. The sources are at
https://github.com/aik/SLOF, and the image currently in qemu is
built from git tag qemu-slof-20191022.
- sgabios (the Serial Graphics Adapter option ROM) provides a means for
legacy x86 software to communicate with an attached serial console as
if a video card were attached. The master sources reside in a subversion
repository at http://sgabios.googlecode.com/svn/trunk. A git mirror is
available at https://git.qemu.org/git/sgabios.git.
- The PXE roms come from the iPXE project. Built with BANNER_TIME 0.
Sources available at http://ipxe.org. Vendor:Device ID -> ROM mapping:
8086:100e -> pxe-e1000.rom
8086:1209 -> pxe-eepro100.rom
1050:0940 -> pxe-ne2k_pci.rom
1022:2000 -> pxe-pcnet.rom
10ec:8139 -> pxe-rtl8139.rom
1af4:1000 -> pxe-virtio.rom
- The sources for the Alpha palcode image is available from:
https://github.com/rth7680/qemu-palcode.git
- The u-boot binary for e500 comes from the upstream denx u-boot project where
it was compiled using the qemu-ppce500 target.
A git mirror is available at: https://git.qemu.org/git/u-boot.git
The hash used to compile the current version is: 2072e72
- Skiboot (https://github.com/open-power/skiboot/) is an OPAL
(OpenPower Abstraction Layer) firmware for OpenPOWER systems. It can
run an hypervisor OS or simply a host OS on the "baremetal"
platform, also known as the PowerNV (Non-Virtualized) platform.
- QemuMacDrivers (https://github.com/ozbenh/QemuMacDrivers) is a project to
provide virtualised drivers for PPC MacOS guests.
- The "edk2-*.fd.bz2" images are platform firmware binaries and matching UEFI
variable store templates built from the TianoCore community's EFI Development
Kit II project
<https://github.com/tianocore/tianocore.github.io/wiki/EDK-II>. The images
were built at git tag "edk2-stable201905". The firmware binaries bundle parts
of the OpenSSL project, at git tag "OpenSSL_1_1_1b" (the OpenSSL tag is a
function of the edk2 tag). Parts of the Berkeley SoftFloat library are
bundled as well, at Release 3e plus a subsequent typo fix (commit
b64af41c3276f97f0e181920400ee056b9c88037), as an OpenSSL dependency on 32-bit
ARM. Licensing information is given in "edk2-licenses.txt". The image files
are described by the JSON documents in the "pc-bios/descriptors" directory,
which conform to the "docs/interop/firmware.json" schema.
- OpenSBI (https://github.com/riscv/opensbi) aims to provide an open-source
reference implementation of the RISC-V Supervisor Binary Interface (SBI)
specifications for platform-specific firmwares executing in M-mode. For all
supported platforms, OpenSBI provides several runtime firmware examples.
These example firmwares can be used to replace the legacy riscv-pk bootloader
and enable the use of well-known bootloaders such as U-Boot.
