I assume the NVAX microcode was patched via its PCS facility by the boot
firmware, not by making a different NVAX die with different microcode I hope,
right? If so the abomination is to be reversed by reflashing the boot ROM with
non-hobbled firmware (stolen from a friend with a non-hobbled machine). They
had flash ROMs like all other NVAXen, right?
