From the start of the day: setup gdt cr0 = 0x40000023 jump to 32bit cr4 = 0x640 setup page tables: page directory attributes: (PAGE_ACCESSED + PAGE_READ_WRITE + PAGE_PRESENT) page tables attributes: (PAGE_2M_MBO + PAGE_ACCESSED + PAGE_DIRTY + PAGE_READ_WRITE + PAGE_PRESENT) I think they map the all 4GB with 2MB pages. set cr3. enable PAE set LME set PG jump to 64bit I think that's it, before running this painfully slow decompression function. Is there something wrong, or maybe missing? Is the hypervisor or maybe the hardware does not do the right thing?
