A boot disk contains a bootable kernel (perhaps using
lilo) and nothing else.

A root disk contains the root filesystem.

The BL2 floppies are not boot/root disks.  The first 
floppy contains the kernel and part of the root 
filesystem.  The second floppy contains the remainder 
of the root filesystem.  When the first floppy boots
(in DOS) it merges the two parts of the root filesystem,
puts them in a ramdisk and boots the kernel (loadlin).

The BL3 floppies are different.  The first floppy is
a self-contained boot/root disk.  It contains both the 
kernel and the root filesystem.  It boots the kernel 
(using lilo) and runs the root filesystem in a ramdisk.  
/etc/rc then creates a second ramdisk, mounts it at 
/usr/X11R6, and loads the contents of the second floppy 
into it.  The second floppy is optional.  Instead of
inserting it, you can press CTRL-C and BL3 will run
normally (except it will not have X, links or modules).

Cheers,
Steven
