If you can get the kernel to be invoked by 32-bit UEFI, it should work. (I've looked at the somewhat terrifying kernel code that makes this work, but I've never tried to use it. I neither own nor want to own a machine with 32-bit UEFI. Supposedly it's possible to test under OVMF.) --Andy _______________________________________________ devel mailing list -- devel@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe send an email to devel-leave@xxxxxxxxxxxxxxxxxxxxxxx
