ipxe errors in ROM

[thomil]

Are you loading the kernel from the command line? iPXE will display two different banners where it promts you to press CTRL+B. If you use the first one to enter the iPXE shell, the BIOS might not have initialized the memory map properly, making parts of your RAM unusable to iPXE. If that's the case it should work if you load the kernel after entering the iPXE shell, after the second iPXE banner.
