S 6.46 Creating a start-up disk for Windows 95
Initiation responsibility: Head of IT Section, IT Security Management
Implementation responsibility: Administrator, IT users
An emergency floppy disk should be created for every Windows 95 computer.
If system problems then arise, it is possible to restart the computer and restore
user-specific profiles where applicable.
For this purpose, on the one hand a system floppy disk is required that can be
used to restart all computers; on the other hand a user/computer-specific
floppy disk containing the individual settings for the user and for the
respective computer.
Creating a system start-up floppy disk
With the register card START-UP DISK under the control panel option
SOFTWARE, a system start-up floppy disk can be created which can be used
for all computers. However, a Windows 95 CD is also required. Alternatively,
an experienced user can manually copy all the relevant files onto a floppy
disk. These include, for example, COMMAND.COM, IO.SYS,
DRVSPACE.BIN and MSDOS.SYS. In this case the german keyboard driver
KEYB.COM and KEYBOARD.SYS, COUNTRY.SYS should also be copied and,
if applicable, further system files (e.g. CD-ROM driver). The german
keyboard can be set with the command KEYB GR, KEYBOARD.SYS. If
applicable, an additional floppy disk can be used for other necessary files, e.g.
an editor, a program for hard disk compression or backup programs.
Creating user/computer-specific floppy disks
For this purpose a previously formatted floppy disk and the program
EMERGENCY RECOVERY UTILITY (ERU) will be required, which are
supplied with the system. The program is not installed as standard but can be
found on the Windows 95 CD-ROM. With the help of this program, the
relevant and up-to-date system files can easily be copied onto a floppy disk; in
particular the file containing the user settings USER.DAT and the file
containing the system settings SYSTEM.DAT. The files USER.DAT and
SYSTEM.DAT contain respective information which is saved in the ini-files
under Windows 3.x. This disk should be brought up-to-date if extensive or
important changes have been made to the computer configuration or the user
settings.
Once a start-up floppy disk and an emergency floppy disk have been created,
they should be checked for computer viruses and write-protection should be
enabled thereafter.
Using a start-up floppy disk
To boot up with the system floppy disk, it must first be placed in the floppy
disk drive, the start sequence in the BIOS prioritised for the floppy disk drive,
and the computer restarted. The computer then boots up in line mode.
