I'll disagree a tiny bit here. One *really annoying* quality of needing 
to use F2/F8/F12 during Windows bootup in a VM (including ESX/vSphere) 
is that sometimes it can be impossible to be quick enough on the 
keyboard to get attention before the OS bootup has begun. By the time 
you can get a console focus it's too late. That can be enormously 
frustrating, and Run Once does help with that.

VMware provides a (relatively hidden) option to mitigate this - there's 
a radiobox in a menu somewhere that effectively says "issue an F2 
immediately when the VM starts to boot up". This sends it straight into 
the BIOS menu. That radiobox has saved what little remains of my hair.

I kind of like "Run Once" for most of my needs, but I do understand 
Blaster's point for his scenario. If we evolve away from Run Once, it 
will be super important to provide the feature similar to VMware to 
force the machine into BIOS after power up.
