v1.18

Raspberry Pi 4 UEFI Firmware v1.18

• Update SMBIOS so that it reports the correct platform manufacturer and BIOS date

NOTE: This firmware archive was altered from the AppVeyor produced version in order to use an older version of start4.elf/fixup4.dat on account of the regression introduced in raspberrypi/firmware#1445

v1.17

Raspberry Pi 4 UEFI Firmware v1.17

• Enable direct USB boot (i.e. you can now boot this firmware straight from USB, without the need for an SD card) [tianocore/edk2-platforms@2254262]
• Enable GPT/MBR ESP support (due to using the latest start4.elf)
• Improve Genet driver [tianocore/edk2-platforms@2242b99]

Note: Booting from USB or from ESP requires a recent-enough version of the Pi EEPROM. If you find that booting from USB or from ESP doesn't work, please visit https://github.com/raspberrypi/rpi-eeprom/releases to update your EEPROM.

• Disable overscan by default in config.txt (#43)

v1.10

Raspberry Pi 4 UEFI Firmware v1.10
