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-20220110. 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- sgabios (the Serial Graphics Adapter option ROM) provides a means for 24 legacy x86 software to communicate with an attached serial console as 25 if a video card were attached. The master sources reside in a subversion 26 repository at http://sgabios.googlecode.com/svn/trunk. A git mirror is 27 available at https://gitlab.com/qemu-project/sgabios.git. 28 29- The PXE roms come from the iPXE project. Built with BANNER_TIME 0. 30 Sources available at http://ipxe.org. Vendor:Device ID -> ROM mapping: 31 32 8086:100e -> pxe-e1000.rom 33 8086:1209 -> pxe-eepro100.rom 34 1050:0940 -> pxe-ne2k_pci.rom 35 1022:2000 -> pxe-pcnet.rom 36 10ec:8139 -> pxe-rtl8139.rom 37 1af4:1000 -> pxe-virtio.rom 38 39- The sources for the Alpha palcode image is available from: 40 https://github.com/rth7680/qemu-palcode.git 41 42- The u-boot binary for e500 comes from the upstream denx u-boot project where 43 it was compiled using the qemu-ppce500 target. 44 A git mirror is available at: https://gitlab.com/qemu-project/u-boot.git 45 The hash used to compile the current version is: 2072e72 46 47- Skiboot (https://github.com/open-power/skiboot/) is an OPAL 48 (OpenPower Abstraction Layer) firmware for OpenPOWER systems. It can 49 run an hypervisor OS or simply a host OS on the "baremetal" 50 platform, also known as the PowerNV (Non-Virtualized) platform. 51 52- QemuMacDrivers (https://github.com/ozbenh/QemuMacDrivers) is a project to 53 provide virtualised drivers for PPC MacOS guests. 54 55- The "edk2-*.fd.bz2" images are platform firmware binaries and matching UEFI 56 variable store templates built from the TianoCore community's EFI Development 57 Kit II project 58 <https://github.com/tianocore/tianocore.github.io/wiki/EDK-II>. The images 59 were built at git tag "edk2-stable202008". The firmware binaries bundle parts 60 of the OpenSSL project, at git tag "OpenSSL_1_1_1g" (the OpenSSL tag is a 61 function of the edk2 tag). Parts of the Berkeley SoftFloat library are 62 bundled as well, at Release 3e plus a subsequent typo fix (commit 63 b64af41c3276f97f0e181920400ee056b9c88037), as an OpenSSL dependency on 32-bit 64 ARM. Licensing information is given in "edk2-licenses.txt". The image files 65 are described by the JSON documents in the "pc-bios/descriptors" directory, 66 which conform to the "docs/interop/firmware.json" schema. 67 68- OpenSBI (https://github.com/riscv/opensbi) aims to provide an open-source 69 reference implementation of the RISC-V Supervisor Binary Interface (SBI) 70 specifications for platform-specific firmwares executing in M-mode. For all 71 supported platforms, OpenSBI provides several runtime firmware examples. 72 These example firmwares can be used to replace the legacy riscv-pk bootloader 73 and enable the use of well-known bootloaders such as U-Boot. 74 OpenSBI is distributed under the terms of the BSD 2-clause license 75 ("Simplified BSD License" or "FreeBSD License", SPDX: BSD-2-Clause). OpenSBI 76 source code also contains code reused from other projects desribed here: 77 https://github.com/riscv/opensbi/blob/master/ThirdPartyNotices.md. 78 79- npcm7xx_bootrom.bin is a simplified, free (Apache 2.0) boot ROM for Nuvoton 80 NPCM7xx BMC devices. It currently implements the bare minimum to load, parse, 81 initialize and run boot images stored in SPI flash, but may grow more 82 features over time as needed.
