@node Supported kernels
@chapter Supported boot targets
X86 support is summarised in following table. ``Yes'' means that kernel works on the given platform, ``crashes'' means an early kernel crash which we hove will be fixed by concerned kernel developpers. ``no'' means GRUB doesn't load given kernel on a given platform. ``headless'' means that the kernel works but lacks console drivers (you can still use serial or network console). In case of ``no'' and ``crashes'' the reason is given in footnote.

@enumerate
@item Requires BIOS
@item Crashes because the memory at 0x0-0x1000 isn't available
@item EFI only
@item 32-bit and 64-bit EFI have different structures and work in different CPU modes so it's not possible to chainload 32-bit bootloader on 64-bit platform and vice-versa
@item Some modules may need to be disabled
@item Requires ACPI
@end enumerate
PowerPC and Sparc ports support only Linux. MIPS port supports Linux and multiboot2.
@chapter Boot tests
As you have seen in previous chapter the support matrix is pretty big and some of the configurations are only rarely used. To ensure the quality bootchecks are available for all x86 targets except EFI chainloader, Appleloader and XNU. All x86 platforms have bootcheck facility except ieee1275. Multiboot, multiboot2, BIOS chainloader, ntldr and freebsd-bootloader boot targets are tested only with a fake kernel images. Only Linux is tested among the payloads using Linux protocols.
