Boot Disks:
A boot disk is a disk where some particular system files reside and
whose root directory is located in the first track of the disk. When
in place in its disk unit, the boot disk can boot the computer's
operating system. The usual boot disk for the Windows system is
the c: disk. A floppy disk can do as a boot disk; so can a CD disk.
The system files involved in the boot disk are few; they are io.sys,
msdos.sys, and command.com. All they need is for their directory to
be in the first track of the disk; and the disk is bootable for DOS on
a PC computer.
Small DOS:
The smldos, MS-DOS interface shell can reside on a boot disk. The
small refers to the boot floppy disk; floppy disks being considered
smaller than CD or hard disks.
Smldos revolves around a DOS prompt program that stands between
the user and regular DOS. The prompt program has two versions.
Both use their own key memory and have pseudo prompts that can
be moved around on the screen; the pseudo prompt uses up much
less of the screen, than does harsh, raw DOS.
There are three versions of smldos:
1) smldos - the regullar version; simply put two
programs on any disk and run them.
2) smldosA - the floppy disk version, for an emergency
boot disk; not for every day use.
3) smldosC - the quick boot version, to have the smldos
directory to be on the c: disk.
The system can be downloaded from: smldosIn.htm
