How does the OS boot OS

[Shubhangi Jadhav]

Hi,

I'm trying to understand the working of LinuxBIOS. The FAQ says that it
uses a real OS is used to load the OS. Can someone elaborate on this ?
    Is it that the kernel image  which you burn along with linuxbios on the
BIOS Flash ROM is copied to RAM, performs the hardware initialization and
then it invokes the other OS which in my case would be linux? How is the
other OS invoked ?

Thanks,
Shubhangi
