The boot sector is loaded by the ROM-BIOS at address 0x07C00. It moves
itself to address 0x9A000, sets up the stack (growing downwards from
0x9B000 to 0x9A200), loads the secondary boot loader at address
0x9B000 and transfers control to it.

The secondary boot loader loads the descriptor table at 0x9D200 and the
sector containing the default command line at 0x9D600. If the default command
line is enabled, its magic number is invalidated and the sector is written
back to disk. This potentially dangerous operation can be disabled by defining
<CODE>LCF_READONLY</CODE> when passing <CODE>second.S</CODE> through <I>cpp</I>. 
Next, the secondary boot loader checks for user input. If either the default is 
used or if the user has specified an alternate image, the options sector is 
loaded at 0x9D600 and the parameter line is constructed at 0x9D800. 
If the resulting line contains the option <CODE>"lock"</CODE>, the command line as
entered by the user (it is saved before the final line is constructed) is 
written to the disk as the new default command line. Also, if a fallback 
command line is set, it is copied to the default command line sector.

Next, the floppy boot sector of that image is
loaded at 0x90000 (The floppy boot sector is only used as a source of
setup information.),
the setup part is loaded at 0x90200 and the kernel part is loaded at 0x10000, 
or, if the kernel has been compiled for being loaded ``high'' (i.e. with 
<CODE>make bzImage</CODE>), it is loaded at 0x100000 instead. During the load

If a different operating system is booted, things are a bit more difficult:
the chain loader is loaded at 0x90200 and the boot sector of the other OS
is loaded at 0x90400. The chain loader moves the partition table (loaded at
0x903BE as part of the chain loader) to 0x00600 and the boot sector to
0x07C00. After that, it passes control to the boot sector.
