Pheonix BIOS Problems

[robert@isadore]

Hi All

Hoping anyone can help, getting extremly annoyed at a compaq presario f500, checked all hardware updated BIOS to F.20 and checked everything i can think of yet still everytime i turn the machine on it boots to the Compaq BIOS screen then continuously beeps at me!!!!!!!!!!!!! if i press any F button it then stops beping and boots up normally and loads vista!!

I have read so many posts trying to sort this but cant find anything on it, does any body know what the problem is?? I have also changed the CMOS battery as this was my first thought replaced the RAM downloaded latest BIOS made sure all drivers are updated and correct, tried to read up on pheonix bios beep codes with no luck and now stuck!!!!

does any body know what the problem is?

I have no idea if this applies to the 'compaq presario f500' in particular, but the following has applied to Pheonix BIOS'es.

1) The CMOS checksum is incorrect (the system assumes the CMOS contents are corrupt and stops the boot so the user can rectify the situation).
2) The CMOS contents are invalid (a parameter has been set out of range, e.g. a CPU speed has been selected that is not supported by the hardware).

There are probably others, but these are the two I most frequently run across.

And the one that took me an hour to catch on to: a laptop with a stuck key
