But now, with the BIOS in UEFI mode and Windows 10 or 11, the missing GOP is causing problems. An old graphics card that only has a VBIOS works well together with an old mainboard BIOS and an old OS such as Windows 7. The term "GOP driver" can be misleading, it doesn't have anything to do with the graphics driver in Windows, it refers to part of the graphics card's firmware. VBIOS-only was common until at least 2016 or 2017, and from then on they started adding a GOP driver to the graphics cards' firmwares. GOP means "Graphics Output Protocol" driver, VBIOS means "Video BIOS". Why? Many of those older graphics cards don't have a so-called GOP driver in their firmware yet, they will only have a VBIOS. But when a modern mainboard's BIOS is in UEFI mode, that can already cause certain problems with older graphics cards. UEFI mode is preferable nowadays for a modern operating system like Windows 10 or 11, and Windows 11 even requires UEFI mode for the BIOS. To be precise, there can also be a hybrid mode of CSM and UEFI where the board chooses the "correct" one, but let's focus on the two pre-set modes. A modern BIOS can be in two modes: Legacy/CSM mode (Compatibility Support Module), and the newer, more modern UEFI mode (Unified Extensible Firmware Interface). The newest BIOS has the feature "Secure Boot" enabled by default, which requires pure UEFI mode. I will try to explain the technical reasons behind this all to the best of my knowledge: But for some older cards, there are solutions, i will list them further down. The only cards that will almost surely be safe from any potential issues are from 2019 and newer. That model (and models older than that, of course) can definitely have problems in combination with this new BIOS. One commonly mentioned card is the RX 580. Possibly a lot of graphics cards from 2018/2017 or older! Which graphics cards can trigger the problems with the newest "Secure Boot" BIOS version? Some users have in fact confirmed my suspicion by now, which is why i'm writing this post, so i can warn more potentially affected users. All the affected users had an older graphics card (at least four or five years old).ĭue to previous troubleshooting of similar issues when using an old graphics card in a modern motherboard, my suspicion immediately fell on that configuration as the trigger for the problems. The BIOS changelog for the MSI boards that this happens with (both Intel- and AMD-based) includes the following: "Change the default setting of Secure Boot". I tried to find the common denominator for the cause of these problems, and two things caught my attention: When a PC speaker is connected, there may also be three beeps to be heard. The most common problems being a blank screen when trying to enter the BIOS, and/or a blank screen until Windows is loaded, or not even getting a picture or a POST at all. Recently, there have been several reports where people updated to the latest BIOS for their MSI motherboard and encountered various - but similar - problems.
