I had the opportunity to met Sun Bing at Xcon and VnSec this year and saw
his talk about BIOS rootkits.

The hardware bits you said are the TOP_SWAP register, used in BIOS updates
to grant against a power failure during the update.

There were a lot of good talks today - in particular GilGil's talk on a
new tool, in the same vein as Cain and Able, called SnoopSpy2 (which he
just open-sourced)[1].

Likewise the talk on Bios and VMWare vulnerabilities was interesting.
Sun Bing had one demo where he got local Administrator on an XP SP2
guest by using a VMWare vulnerability (unreleased). He also had several
guest-&gt;host escape techniques (VMWare dieing due to memory access
failures and such) - no working PoC here, just crashes. He said (via
translator, so it's possible there was confusion) that his bugs only
affected VMWare Workstation and not VMWare ESX. The Bios tricks were
interesting as well - essentially they were documentation on how to
install useful Bios rootkits or perform a really annoying DoS by
flipping one of the hardware bits (would require complete power drain to
reset).
