Hey, i have a problem. Link script isn't working. 'ld' says "undefined symbo KERNEL_LMA". What does it mean? Should I define this address?
Thanks in advance.

Hi bzt,

Is this code still available anywhere?

It has been evolved to the BOOTBOOT Protocol and reference implementations. That linked repo contained the BIOS/Multiboot version in Assembly, and a very naive UEFI version. Multiple platforms and several booting environments has been added since. The example 64 bit kernel hasn't changed a bit, only compiled for ARM too.

Cheers,
bzt
