qemu_efi
In sometimes, we need boot ubuntu system on a native UEFI 32-bit BIOS machine, but all existing OS including window/linux only provides EFI64-bit ISO image, the only exception is apple Mac OS. So it almost impossible to install any OS on a pure native UEFI 32-bit BIOS based system.
So this package provides:
-
- Tools to create raw GPT image
-
- Pre-build OVMF 32/64-bit UEFI BIOS binary with debug build and serial output
-
- The image ubuntu32_gpt.raw.xz for ubuntu server 32bit which can be boot with 2) OVMF UEFI BIOS IA32 binary in qemu.
-
- The image ubuntu64_gpt.raw.xz for ubuntu server 64bit which can be boot with 2) OVMF UEFI BIOS X64 binary in qemu.
You can use the RAW image in above 3 & 4 to create USB boot disk to boot with UEFI 32-bit BIOS or UEFI 64-bit BIOS.
Beyond that, you can use above 3) & 4) to do whole boot path debug from BIOS to OS for native UEFI 32&64, since all serial output are redirected to a single log file.
Please reference https://docs.google.com/document/d/1l9nopR-M2ZGLFRTZ7nUzeXJCcvBHtfGyCVr07DPN_JY/pub for detail.
Play Steps:
a) Get ubuntu32_gpt.raw.xz and ubuntu64_gpt.raw.xz from https://skydrive.live.com/?cid=ce442b77cccd3a56&id=CE442B77CCCD3A56%217492
Because github.com disallow a single file exceed 100M, so ...
Also you can build/install ubuntu32_gpt.raw and ubuntu64_gpt.raw by self according to the steps in above reference link.
b) Put ubuntu32_gpt.raw.xz and ubuntu64_gpt.raw.xz to images folder.
c) Run "qemu_linux32.sh efi" to start the debug version BIOS + ubuntu from the disk image ubuntu32_gpt.raw
d) Run "qemu_linux64.sh efi" to start the debug version BIOS + ubuntu from the disk image ubuntu64_gpt.raw
Create USB disk for ubuntu image
(Assume your usb disk is located at /dev/sdb in host machine)
dd if=images/ubuntu32_gpt.raw of=/dev/sdb
dd if=images/ubuntu64_gpt.raw of=/dev/sdb
