Enabling Hardware Virtualisation On A Toshiba Tecra

I've been doing a bit of playing recently with Virtual PC (and struggling, but that's a subject for a longer post). One of the options in Virtual PC is to selectively enable hardware-assisted virtualisation, however the option was greyed out on my Toshiba Tecra. Until yesterday when a chance comment by a colleague (who's also looking at VirtualPC to enable some work with SQL Server 2000 Analysis Services) let me know how to enable it...

As your laptop boots, hit [Esc] to get into the BIOS setup. You should then get a prompt at the top of the screen that reads 'Check system and press F1' - hit F1 to get into the BIOS. On the first page of the BIOS on the right-hand side is a pane for virtualisation, with a setting for enabling it - it was disabled on mine, I suspect/assume that's how they leave the factory. Highlight the setting, hit [Space] to change it, then hit [End] to save your changes and restart the machine. Let it boot into Windows, fire up Virtual PC, and you should now find that hardware-assisted virtualisation is enabled.

Edit: In my excitement to post this, there was something I forgot to add. I'd saved my running virtual machines, however when I fired them up again after enabling hardware virtualisation they would not run correctly. I needed to clear the saved state and fire them up again from scratch. Not an issue particularly, just something to be aware of.
