Question Gigabyte motherboard BIOS checksum - only 4 letters

[dor_13]

I noticed that on the download page of the Gigabyte BIOS , there is a checksum with only 4 letters.

For example:
https://www.gigabyte.com/Motherboard/B660M-POWER-DDR4-rev-10/support#support-dl-bios

Why so few letters?
And which checksum is that?

It shows in the Q Flash utility after you flash the bios, so I guess its there to confirm it matches what is on site.
its an internal hash - link

Not sure if its the same checksum that is used for booting

Before the boot code in the BIOS is executed, though, the BIOS data is checked for authenticity by comparing one of its values, known as a checksum, against a value stored in a memory chip called CMOS; if the values match, it means that everything is working correctly, so the boot code is executed and the computer starts normally.
