In response to a members question about the Bios and Flashing I will add to this thread.
Your Bios (Basic Input Output System) is EPROM (Electronically Programmable Read Only Memory) Firmware that contains an instruction set that tells your CPU, Ram, Motherboard, Hard Drive etc. how to interpret the various commands that pass amongst these devices. Flashing the Bios can add to or change these interpretations to fix issues of incompatibility due to a poor instruction set or outdated instructions.
In the situation described in this topic where our member has:
an incompatibility with the PCI slot...something about 2.1 (the motherboard) versus 2.2 (the card)compliance.
If the Bios only recognizes 2.1 compliance, it can't interpret the commands sent by a 2.2 card. Sometimes a Bios Flash (if the updated Bios update covers this issue) can update the Bios such that the instruction set can now correctly interpret these commands and allow a newer device to work in an older machine.
Most often a Bios Flash is designed to update a Motherboards ability to accept a newer CPU. This is because CPU makers and Motherboard makers are always trying to keep up with or outrace each other in terms of the latest technology. By the time a Motherboard is a few months old some geek is trying to stuff the leading edge CPU into it but the Bios makers (when the Motherboard was released for sale) did not have enough information from the CPU makers in order to write the Bios instruction set for the next generation CPU because these CPU's were still under going design and testing and even the CPU makers weren't sure what those instruction sets were going to be.
Before you flash a Bios you must
determine whether that Flash will address whatever issue you are trying to correct or its not a worthwhile endeavour.A Bios Flash is not something to do for the sake of doing it. If you Flash a Bios and for some reason that flash is interrupted (say by a power disruption or some other failure) the Motherboard will become useless. jumpkutz
if you can let me know the Model number of your Dell I'll take a look around and see what I can find out. Its a Dimension 500 Series but we need the Model number. Usually this can be found on the back of a Dell tower.
