When everyone says dont mess with bios cuz it can brick your pc cuz bios is specifically designed for specific installed components, then how come when you change the wifi card in laptop, or change ssd, or ram, mobo doesnt get bricked but works with new components just fine?

Is uefi or bios specifically a motherboard connected thing? Regardless of other components on mobo?

So If I have a Tongafang ODM motherboard with ProStar uefi on it, I can theoretically download Gigabyte uefi for the same mobo and run without bricking the device?
You should never assume that you can use the UEFI/BIOS for one motherboard on a different make/model.

While in theory, it may work. You are more likely to brick the motherboard you are trying to use.

What specifically are you trying to accomplish?
 
I would suggest you do some digging regarding BIOS and how it's possible to literally convert functional motherboards into e-waste by flashing the wrong BIOS onto them(meaning taking another board's BIOS not listed on the original motherboard's BIOS list). You should also know that some BIOS have a white list, some Dell's and HP's had them in the past.

Side note, how is this thread related to PC Gaming?
 
how are half the posts here related to PC gaming?

flashing wrong bios onto a motherboard could leave you with a nice wall hanging but a pretty useless motherboard.


Up until 2009 all PC used Legacy bios.

They didn't know what a mouse was, you had to use arrow keys on kb to navigate them. They weren't very modifiable, they had to be a certain size and were only 32bit.

They only used Legacy boot method (it wasn't called legacy yet)

it uses MBR - MBR stands for Master Boot record

MBR drives can only have 4 partitions and max drive size is 2.2tb

Boot partition on MBR drives is always 1st partition on drive



In 2009 UEFI was released to replace Legacy bios. UEFI stands for Unified Extensible Firmware Interface

it uses a graphical interface that knows what a mouse is

It can be expanded and have new features added

It can use UEFI or Legacy boot method

It can boot legacy drives since it was made to replace BIOS, can't not be backwards compatible.

It supports GPT drives. GPT stands for GUID (GUID = Global Unique ID - every GPT drive on earth has its own number) Partition Table

GPT drives can have up to 256 partitions and max drive size is a silly 18.8 million tb

Boot partition on a GPT drive can be anywhere.

All PC before win 7 used MBR

Win 7 32bit uses MBR only

Win 7 64bit can be MBR or GPT

win 10 64 bit can also be either but it prefers GPT

Win 11 only supports GPT



UEFI boot method can boot both MBR & GPT drives (as you found in other thread)

Legacy can only boot MBR, it doesn't know what GPT is for booting

What is a white list?
