Tools and Resources

I was going to initially use GNU-EFI and GCC for this project however i decided to use the following tools for more flexibility:

• Clang
• LLVM Linker
• QEMU
• OVMF

Bootloader configuration file

The bootloader uses a configuration file which is reads to determine which kernel image and initrd image to use:

• The configuration file should be named 'simple.cfg' and placed in the root of the EFI partition
• The configuration file should contain a single line in the following format: LinuxKernelImageName#InitRDFileName
• LinuxKernelImageName should be the name of the kernel image
• Next it should be followed by a single hash #
• InitRDFileName should be the name of the initrd file name
