BIOS Update / Flashing
- Updating your BIOS can be *very* dangerous. Don't touch a working system; a bad BIOS flashing can result in a computer not rebooting.
- If something goes wrong with the BIOS update, be very careful. You can repair the motherboard by removing the BIOS chip and replacing it with a new one.
- You must never remove the plastic around the BIOS chip. *Only* the BIOS chip. If you remove the plastic it'll be next to impossible to replace it and your motherboard will become junk.
Setting up your own box
- Motherboards usually come with their own I/O panel - a metal shield that should be put at the end of the computer case. To fix it, push it from the inside of the motherboards while applying pressure simultaneously at all 4 angles.
- Motherboards don't contain a lot of cables - those come from either the power supply block or the case itself (cables are needed to link the USB ports in the front of the case for instance).
Screwing the motherboard to the case
- Be very careful - do not bend the motherboard in any way! Never. Some of the holes in the motherboard may align with holes in the case where there is not any preinstalled "brass standoffs". In that case, you must first install those brass standoffs, and only then attempt to place your motherboard on those brass standoffs.
Identifying your motherboard model
- On Linux just run dmidecode. It will give your motherboard model.
