Changelog

Unreleased

v2.8.0 2024-05-02

  • Add support for building as an AArch64 (ARM64) binary (sponsored by 2Pint Software).

  • Fix forcing of text mode output when multiple displays are present.

  • Add support for building with the clang compiler.

  • Replace efireloc with iPXE's elf2efi tool for converting ELF binaries to PE format.

  • Update to latest EDK2 headers.

v2.7.6 2023-08-16

  • Use separate .text and .data sections for W^X compatibility.

v2.7.5 2023-01-25

  • Support images compressed using the XPRESS compression scheme.

  • Fix building with GCC 12

  • Fix use of index=N when no injected files are present.

v2.7.4 2022-01-20

v2.7.3 2021-04-30

  • Fix extraction of embedded bootmgr.exe from Windows 10 versions of bootmgr.

v2.7.2 2021-02-22

  • Fix BIOS booting of 32-bit versions of Windows 8 and above with more than 4GB of RAM.

  • Ignore subdirectories when booting from a USB key (or other real filesystem), thereby avoiding potential filename collisions.

  • Avoid potential infinite loops when retrieving the BIOS memory map.

v2.7.1 2021-02-11

  • Extract BCD, boot.sdi, and standard boot font files automatically from the .wim image.

  • Use paging and Physical Address Extensions (PAE) to place the initrd above 4GB if possible, thereby allowing larger .wim images to be used on BIOS systems (sponsored by Digital Intelligence).

  • Enable stack protection for both BIOS and UEFI builds.

  • Tidy up debug output that typically disrupts the loading screen progress bar.

  • Add quiet command-line option to inhibit all debug output (sponsored by 2Pint Software).

  • Create fully automated tests of an HTTP boot via iPXE and wimboot into multiple versions of Windows.

  • Migrate from Travis CI to GitHub actions.

v2.6.0 2017-05-10

  • Dynamically patch the .wim image to allow files to be injected in \Windows\System32, allowing for fine-grained control of the boot process (sponsored by 2Pint Software).

  • Use Coverity Scan for ongoing static analysis.

v2.5.2 2016-02-09

  • Validate signed binaries to ensure that no malicious code was injected in the UEFI Secure Boot signing process.

  • Fix identification of terminating character in strtoul().

v2.5.1 2015-09-22

  • Work around broken 32-bit PE executable parsing in the UEFI Secure Boot signing process.

  • Provide UEFI Secure Boot signed binaries.

v2.5.0 2015-08-28

  • Limit initrd to the low 2GB of memory to work around versions of Windows that assume the ability to use arbitrary fixed addresses above 0x80000000.

  • Prepare for UEFI Secure Boot signing.

v2.4.1 2014-12-08

  • Ignore initrdfile command-line argument that may be appended by syslinux.

v2.4.0 2014-11-07

  • Provide space for a protected-mode interrupt descriptor table, avoiding RSOD crashes on systems such as HP DL360p Gen8 that happen to occasionally generate IRQ 5 during boot.

v2.3.0 2014-09-24

  • Fix building of 32-bit UEFI binary.

v2.2.5 2014-09-23

  • Fix construction of FAT long filenames that are exactly 12 characters in length.

v2.2.4 2014-09-09

  • Work around UEFI firmware that fails to populate the DeviceHandle in EFI_LOADED_IMAGE_PROTOCOL.

v2.2.3 2014-09-03

  • Display an optional prompt when using the pause command-line option.

v2.2.2 2014-09-03

  • Generate position-independent code for UEFI, to allow for relocation to arbitrary 64-bit addresses.

  • Fix assorted build toolchain issues.

v2.2.1 2014-09-02

  • Respect the selected boot index when extracting files from the .wim image.

  • Add pause command-line option to allow for inspection of debug output before transferring control to bootmgr.exe or bootmgfw.efi.

v2.2.0 2014-09-02

  • Add the ability to extract individual files from the .wim image.

  • Extract bootmgr.exe or bootmgfw.efi automatically from the .wim image.

v2.1.0 2014-08-30

  • Dynamically patch BCD file to allow the same file to be used for both BIOS and UEFI boot.

  • Force bootmgfw.efi to use text mode (as already done for bootmgr.exe).

  • Add rawbcd command-line option to disable dynamic BCD patching.

  • Add gui command-line option to disable forced text mode output.

  • Add index=N command-line option to allow a boot image to be selected dynamically at runtime.

v2.0.0 2014-08-29

  • Support booting on UEFI systems (sponsored by Jump Trading).

  • Retrieve initrd files via EFI_SIMPLE_FILE_SYSTEM_PROTOCOL.

  • Expose the virtual FAT filesystem to bootmgfw.efi via EFI_BLOCK_IO_PROTOCOL.

  • Build as a hybrid 32-bit BIOS and 64-bit UEFI binary.

v1.0.6 2014-06-22

  • Make real-mode setup code relocatable.

v1.0.5 2014-05-17

  • Force bootmgr.exe to use text mode since it is unable to display error messages in graphical mode (unless the appropriate set of font files has been added).

v1.0.4 2014-03-19

  • Fix the XCA decompressor to match the undocumented behaviour of the compressor when crossing 64kB block boundaries.
