Vista users: how do you flash custom Titan ROMs?

[kalibar]

Hey guys, I'm currently on Vista (32-bit) and have found that short of dual-booting it's a real pain in the ass to get my PC setup to flash custom ROMs on the Titan. Back when I was a GSM customer and owned a Hermes, I used mrvanx's excellent Vista guide for Hermes, but I keep having problems getting that to work properly for my Titan -- seems inconsistent at best.

Are you guys dual-booting XP, just finding an XP machine to use while you flash, or virtualizing XP? Maybe it's something quirky with my setup (shouldn't be, as I have a July 2007 Core 2 Duo ThinkPad), but I'm finding that I get really slow XP performance under the free VMware Server.

What's the best/most efficient way to flash custom Titan ROMs?
