What Are You Trying To Do?
by Grif Thomas Forum moderator / September 8, 2006 3:14 PM PDT
In reply to: NO OS BUT......

You've told us nothing about the computer or what you're trying to do.. Is the operating system already installed? Does this message pop up at start up? Is it an old computer? The error can come up when the motherboard is dying. Or sometimes when the CMOS battery needs replacing. Have you tried removing the CMOS battery for 5 minutes, then replacing it with a new one? The default settings should reset and hopefully it fixes the issue.

Have you installed a new piece of hardware recently?

Or are you trying to install the OS from a CD to a new hard drive? Old hard drive?

Hope this helps and let us know more.

Replace CMOS regardless

Replace the CMOS battery as 3yrs. or more, its about time. Install new battery then go into the bios and enter the setting as they should be. Save all of it before exiting the bios area. Reboot, and then check the results, it may fault again, if so, reboot to re-enter bios and verify system setting. Make sure if any "jumper" need it be set or return to NOT clear the bios, read your manual or inspect the mtrbd. for such what its postiton should be. OK.

You took the battery out.

Waited 5 mins.

Put the old battery back in and had the same problem.

Next step....take the battery out and 'replace' it with a new one.

Cheap test they are only a few bucks.
