Question Replacing bios chips

[Viper=tr=]

A bunch of old timers used to help out people with corrupted bios from bad flashes or corrupted from overclocking.
We used to boot up into windows. Extract the boards chip. Place in a blank chip. Flash any bios needed. Then put back the boards chip with its bios.
Anyone do this anymore with AMD boards where the bios has to be upgraded to take certain CPU's? The blank chips are cheap and easy to take out.

why not just flash the bios the normal way?

Some boards are bricked from bad flashes.

Some computer repair shops have the necessary skills and tools. You need a hot air workstation to unsolder the old BIOS from a typical mobo and a PROM programmer to load the appropriate firmware, before soldering the chip back on the board. Check your local repair centre and see if they offer this service.

Saudering is always the worst. It can lead to you doing it again or something will mess up. Programming it is not the hardest but complex

Ussualy on a standard PC mother board they slip out with a simple socket extractor.

Yep, that is interesting to

On my older boards, it was common for the BIOS to come in the form of an 8-pin DIL chip, or a chip with contacts on all four sides fitted in a socket, for which I have a PLCC tool.

On my modern boards, the BIOS is often soldered in place (a cost saving feature?).

This article describes various methods to remove a BIOS chip including de-soldering. You can sometimes re-program chips in-situ with a clamp on device attached to a programmer.

Here is a video of someone unsoldering a BIOS chip with a hot air blower.

I hadn't come across the term 'saudering' before. Must be because I live on the other side of the Atlantic. Two nations divided by a common language?

Tends to not be worth the costs. Almost all chips are now soldered to the board. You need a hot air station to safely remove them and even then it is very easy to damage other parts that are nearby.

One of the larger problems is even if you buy a programmer the bios images you download have to be modified. They are not in the same format as the files you need when you directly write them to the chips.

Note the support for a certain CPU chip sometimes is more than just the bios. If a motherboard can support a CPU you will generally find the bios on the manufacture site. It could be the motherboard does not have enough power to run the newer cpu.

Soldering*, sorry, English is not my first language...
There was some old ASRock board that had removable BIOS chips; but not sure of the model

I replaced a surface mount chip on the HDMI port on a PlayStation 4 once, doing it successfully with the equipment I had was so hit and miss I don't think I would dare try on a mobo, but I have replaced capacitors
if you try it let us know the results
