Today I received an allegedly broken ASUS PRIME Z690-P DDR4 motherboard.
The seller of the board has written the board sometimes starts, sometime not, and it is not stable, crashes sometimies during operation in Windows.
I powered the board, and it went straight to the BIOS screen, showing BIOS version 0407.
After first next reset the board surprisingly went directly into BIOS update screen and started without asking a BIOS update and it correctly updated the BIOS to version 1620 !
There was no pendrive with an image attached to the board, only thing on the board was my testing m.2 Windows boot disk and a CPU with Integral GPU.
I was so astonished how this is possible ?
From where did the board take the v1620 image to update - this board does not have a second BIOS - although it has 2 BIOS chips, but the BIOS image is divided between this 2 chips and this is one single BIOS image.
Can anybody explain how this update is possible without an external pendrive ?
Could this be a malfunction or intentional function of the "BIOS Image Rollback Support" ?
After that update I made a further update to newest version v3212 and made several boots to windows.
After a few of these boots into Windows it crashed just during operation a few times, but finally after 3-4 crashes, the board works now stable.
I think there must have been some flaw in the original BIOS, and it propagated during the updates to the newest BIOS, maybe after a few crashes the BIOS or the PCH corrected some data, and now the board works stable, but still all this is a big question mark for me. Maybe the crashes were only the reason of my Windows installation, which I use for many different boards, and they did not have anything to do with what reported the seller of the board ?
