    No, it does not. I know that my desktop PC reboots with a beep (and
    shows CPU information) from Linux - and it does not beep when rebooting
    from Windows 98.
    Some BIOSes don't like when some devices are in some state. One example
    is my DTK FortisPro TOP-5A notebook - when rebooted from Linux, it hangs
    during POST - the fix was to add setpci <someting> to shutdown scripts
    to zero-out some cardbus controller registers.
