I've got one of those myself. I just loaded Small Business Server 2003
on it as a test run to see how it would go.
It would qualify as a bios-locked oem machine--the product ID on the
sticker on the bottom isn't entered into the registry as part of
Activation, 'cause you are never asked to activate it. Some older WGA
versions required you to get that number off the bottom and enter it as
part of the WGA check, but I think they have eliminated that step these
days.
So that might explain the messages--there's no valid product ID wherever
WGA is looking for it when it has never been through Activation or
WGA--and after WGA there's something there--not sure what, but obviously
it passes.
I used BootItNG to scale the C partition down to half the drive size, and
created a second partition which I use for other OS versions--I test Vista
on it, and I'm running SBS 2003 for a week or so just to be sure I know my
way around it for a deployment in an office that I'm working with.
Nice little machine, but mine has a failure between the power jack on the
back and the motherboard--it doesn't recognize when the power supply is
connected, and thus won't charge the battery or power the laptop.
Fortunately, it does work with the port replicator, which connects through
the stuff on the bottom--so far, I'm living with it rather than sending it
in to replace the motherboard.
