Any ideas? thanks
https://www.reddit.com/r/coreboot/comments/nuf2qh/coreboot_wtianocore_on_t420_only_2gb_ram_reported/?sort=new I have this problem too. ESC key shows 8GB, Memmap in efi shell shows 2gb. Osx says 8gb. Ubuntu says 2gb (macbookpro10,1) uefipayload.. do u need the hw_probe info? Can I ask in tiancore.buzilla ? fastly is down why the 6gb ram is reserved??
