Yes, if I ever lose my keys,
Away-ay-ay... I'll just have to use my mouse.
And if I ever lose my drive, all my data's fried alive,
Yes, if I ever lose my drive, ... I'll reboot from floppies ...
If I lose my parity, I won't beg for charity,
Yes, if I lose my parity ... I'll just have to go salute [Ctrl+Alt+Del keys]
And if I lose my UMBs, if my NEAT set BTDs,

ROM Shadow - 80286 machines have trouble using the RAM between 640K and 1024K, called the Upper Memory Block or UMB. Many machines, if equipped with a chipset such as the Chips & Technologies NEAT chipset, can use that space to copy their slower ROM (Read Only Memory) and Video RAM information into that area, and this process is known as "shadowing" The reference in the last verse to BTDs is much more mundane. The term means "Bites The Dust".
