5. MS-Windows
5.1 Overview
The MASK ROM drive (E:) of this terminals has MS-Windows installed in it.
However, MS-Windows cannot be booted directly from this MASK ROM drive. This is because
MS-Windows will overwrite some of the INI files at start up. However, since all files including the
INI files are initially located in the MASK ROM drive, they cannot be overwritten, therefore an
error will result. To avoid this problem, it is necessary to copy some of the files in the write-permit
drive (D:) before booting MS-Windows (refer to the description about WINST.EXE). This
installation method is called “network install” and is employed if multiple users share MS-Windows
on the network. With respect to the MS-Windows operating environment of this terminal (as shown
in Fig. 5.1 below), D:
WINDOWS is considered the disk of a local computer and E:WINDOWS
is considered the shared directory on the network.
Fig. 5.1
The advantage of this method is that a limited disk space can be used efficiently by allocating a very
large volume of the main part of MS-Windows, various drivers programs, and INI files to write
setups to the user drive while referencing the inside of the MASK ROM.
