To edit system files

C A U T I O N

Make a backup copy of any system file you plan to edit. If you accidentally make an
improper change, it may prevent your system from working properly. You can use
the backup copy to restore the original version.

1. In the Program Manager window, from the File menu choose Run.
2. Type sysedit and choose OK.
3. Activate the window for the file you want to edit and make the changes.
4. From the File menu, choose Save to save the changes for the system file in the

active window.

Editing System Files

Click Start and Run, then type sysedit .

If you want to activate the changes you made, exit Program Manager (and Windows),
then reboot the OmniBook (press

CTRL+ALT+DEL

). If the system doesn’t reboot

successfully, see the next topic.

Hint

You can change the multiple configurations provided in the CONFIG.SYS and
AUTOEXEC.BAT files. Copy or move commands into different sections of the file as
needed.

The original system files contain commands that enable the OmniBook to operate
properly for all supported uses. If your usage requires different commands—and you
have an understanding of how the system files function—you can edit the commands in
the system files. For best results, follow these guidelines:

•

Don’t delete command lines—instead, “remark” them so they’re not executed. For
CONFIG.SYS and AUTOEXEC.BAT, insert “

rem

” at the beginnings of those

lines. For WIN.INI and SYSTEM.INI, insert “;” at the beginnings of those lines. If
necessary, you can easily restore the original commands.

•

For CONFIG.SYS and AUTOEXEC.BAT, note the comments that describe the
commands. Use them to decide whether you need individual commands for your
situation.

•

Be cautious about removing the command for a driver or program whose name
starts with “OB”—it’s usually a specialized command that provides important
OmniBook functionality.

To recover system files

1. If your system doesn’t reboot successfully, see

“To reboot the OmniBook”

2. If you copied your system files before editing them, restore them from the copies

you made.
–or–
If you back up your files periodically, retrieve the previous version of a system file
from your most recent backup.
