Hello, Markie.

I'm running the 10.04-rc-desktop-amd64 in 2GiB on my Asus A6K laptop: 
I've just upgraded to the rc today: I've been tracking the alpha/beta 
releases, but decided to do a clean install from a USB stick today to 
get rid of the junk that I've accumulated during all the upgrades ;-)

Virtual box doesn't execute the image, it runs the CPU's 'supervisor' 
commands: The VB 'images' are just containers for virtual filesystems 
containing the code. The 'guest' OS's are independent of the 'host' OS.

I've been running with /home on a USB drive for a while too, deciding if 
I should upgrade to ext4 - Decided I would do that today + OK so far!

Well, it's because the BIOS tells GRUB what it thinks the disks are 
while the USB disk is still connected...

I'm still not able to get Thunderbird running 'Lightning' in 64-bit, 
though - Anyone else succeeded? I've installed the ia32 libraries.

I'm still undecided about Evolution, but at least the Calendar works!

Bye,

   Tony.
