Rick B.8, also try a "hard" reset of the NVRAM following this procedure....
With the machine unplugged from the wall remove the battery from the motherboard. Then with the machine still unplugged press the On button for several seconds to dissipate any remaining electrical charge on the motherboard. Then re-install the battery, plug the machine back into the wall and see if it will boot normally.
Click here for the "how to" on removing the battery. Although the link is for the 8100 model, the information on the removal procedure is the same. For some reason Dell left out that section in the 8200 model's User Guide.
With over 30,000 posts (through early 2007), Rickmktg hasn't bought a Dell computer since July 2005, but has bought two Lenovo laptops...
Rick B.8, I'm assuming that the battery removal got rid of the checkpoint error? If so then try clearing the NVRAM again only this time do it through the BIOS Setup by following the procedure found by clicking here. Possibly by clearing of NVRAM again the system will redetect the drives now that the checkpoint error is gone.
As for flashing the BIOS that depends on your currently installed version. In the BIOS history for your model there was nothing listed that fixed or improved on drive detection at boot up. Starting with version A05 there was a fix for trouble-shooting "unknown" drive problems. This is what it offered..... "Fixed issue with UNKNOWN devices in System Setup for IDE devices. If a failure occurs, now check the second IDE cable for devices."
If the problem continues then I would try disconnecting a drive one at a time to see how the system boots up. I would also clear the NVRAM after each disconnection. If the system boots up without error with an individual drive disconnected then I would suspect that drive as being the problem.
