Right now I have Legacy GRUB installed as the primary boot loader on the MBR. From there I can boot GRUB via 'kernel /grub2/core.img'. However, once I try to load a kernel it reports "cannot allocate real mode pages". lsmmap reports "base_addr - 0x100000, length = 0x3fffc00, type = 0x1". What can I do to debug this further? - Matthew
