Troubleshooting

Solving Basic Problems

If the OmniBook doesn’t reboot successfully (Windows for Workgroups)

If your operating system is MS-DOS or Windows for Workgroups

∙If no text is displayed, or if the system stops before you see any text about MS-DOS, the OmniBook might require service. Try rebooting again. You can try to start the System Configuration Utility (press F2 during reboot), then select Factory Default Settings from the Default menu, and then select Save from the Exit menu.

∙If you see error messages during startup, but Windows starts or you get an MS-DOS prompt, exit Windows (if necessary), and type scandisk to fix problems with drive C. Then press CTRL+ALT+DEL to reboot—but at the “MS-DOS Startup Menu,” press F8 ENTER and step through each startup command to find where the problem occurs. Repair or restore the necessary files as indicated.

∙If you see text about MS-DOS but things stop before Windows starts or before you get an MS-DOS prompt, insert the Support Utility disk or other boot disk in the floppy drive, then press CTRL+ALT+DEL to reboot from drive A. (Note that the System Configuration Utility must have System, Boot Devices set to boot FDD First.) If the OmniBook doesn’t reboot from a floppy boot disk, the OmniBook probably requires service.

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)

sys a: c: (to restore MS-DOS boot 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) and c:\dos\scandisk (to repair any file defects).

Last resort: The following commands delete all files on drive C, so try to back up your data files. You must reinstall your files after running these commands:

fdisk (to verify partitions on drive C)

Then restore the operating system and the special drivers and software from the Recovery CD—see page 1-19.
