Rebbot

When i start my computer it opens at a screen giving me a choice of F1 to continue or delete to enter set up and a message saying CPU unworkable or has changed. If i use delete to enter setup and check for changes or set defaults then choose save and  exit the computer will not reboot and i have to shut down and use my rescue disk to get going again Thi is an abit BH6 board and a 400mhz celeron CPU and is  only two months old it worked fine up until now

Will it boot up if you choose the F1 option?
Do you change something when you go into CMOS setup?
Have you checked all setting there to see what has changed?

It sounds like maybe the CPU is going bad or something?? But lets not jump to conclusions yet.

Won't it still boot at the slower speed? I haven't play much with the PII chips but I know you can run the AMD chips at a slower speed without any problems. No performace until you set the correct speed but it will still boot???
Whoops Celeron chip?
The BH-6 will default to 233mhz but it also defaults to error in the speed so the chip won't past the test so it will lock. If you change it to disable you can play with the bus but the Celery is locked on the multiplier so it won't work off its true clock.
Here the board is setting to default at boot so it is locking without correcting it. Also the board won't go below the 66 bus so you can't run the Celery at less than 400. If you want to see it pick up a little change the bus to 75 instaed of 66 and it'll run 450 as good as 400

I really think he's got a bad battery even if it is only two months old.

Correct me if I am wrong but if it default to 233 then I assume it is not PNP CPU capable and as such then How would it know that the CPU wasn't a 233 and set as error?
 
Will the celeron run at the slower speed?

I am not questioning your comment as wrong but trying to understand the difference. I had a AMD 400 on a MB with (software jumpers) and if you reset the CMOS or remove battery to reset then it default back to 166, but it boots up just fine and will run just fine, just at a slower speed. The celeron won't do the same?? or maybe this model of MB will not allow it?
The board defaults to its slowest speed 3.5x at 66 bus=233. The Celeron won't run off its multiplier 4.5x so it can't run at 3.5x thus the chip would fail. It is as you last stated <The celeron won't do the same> not so much that the board knows the difference but the chip does and that will set the error off to the board so the board first tells you it is wrong as Horman stated <CPU unworkable or has changed> and if you F1 and go on the chip fails. The AMD wasn't locked so it would run at what you set it. Intel was that way till a couple years ago. I got a 300 PII that isn't locked and the BH-6 would let it run at the 233.

Thanks I changed the battery and all is well I kept shying away from the battery as computer is new. When i took the battery out it was stamped Jan 1993 James Horman
Horman,
Glad to see you got it fixed. Let us know if we can help again
