Description of problem: This is my kernel and it's multiboot loader. It passed the check of `grub-file`, but QEMU could not load it. ``` qemu-system-i386: Error loading uncompressed kernel without PVH ELF Note ``` When I add `-machine type=pc-i440fx-3.1`, QEMU shows `qemu: linux kernel too old to load a ram disk` or `qemu: invalid kernel header`. The multiboot file is linked with `ld.lld -s -o`. [toop](/uploads/7f230dc39d6a3a8c43c4c720d31878c6/toop)[multiboot](/uploads/59faa4607dc2837b54c89b35db6f206a/multiboot)
