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
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—then
choose the Minimum Startup option. (If the unit doesn’t reboot from a floppy
boot disk, the unit 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:
scandisk c: (to repair any defects)
sys a: c: (to restore core MS-DOS files).
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)
Then reinstall all of the original files on drive C using the HP Recovery CD and
Support Utility disk. See “If you need to install all original files on drive C” in this
section.
