I'll have a look.

Shouldn't have done, from what I've read the people who broke theirs
more were those who ran IBAUTIL on machines they shouldn't have done
so (i.e. laptops with integrated LAN) - that util is for discrete
adapters only, which is why I've made sure not to try it and only use
the vendor-supplied BIOS image.

At least from what I can see, re-flashing the BIOS had zero impact, it
doesn't seem to have made the problem _worse_.
