Troubleshooting
Solving Basic Problems
If the OmniBook doesn't reboot successfully
If your operating system is MS-DOS or Windows for Workgroups
If no text is displayed, or if things stop before you see any text about MS-DOS,
the unit probably requires service.
If you see error messages during startup, but Windows starts or you get an
MS-DOS prompt, exit Windows. Then type scandisk to fix problems with
drive C. Then press
Menu," press
F8 ENTER

you get an MS-DOS prompt, insert the Support Utility disk or other boot disk in
the floppy drive, then press
choose the Minimum Startup option. (If the unit doesn't reboot from a floppy

If it reboots, type dir c: to see if drive C contains valid files. Then try the
following:
If drive C has valid files, try typing these commands: c:\dos\scandisk
(to repair any defects) and sys a: c: (to restore core MS-DOS files).
Try typing each of these commands to see if it fixes the problem:
fdisk /mbr (to repair only the boot sector of drive C)
c:\dos\scandisk (to repair any file defects)
Last resort: The following commands delete all files on drive C, so you must
reinstall your files after running these commands:
fdisk (to reinitialize drive C)
format c: /u (to prepare drive C for storing data)
Reinstall all of the original files on drive C—see "If you need to install all
