Topic: Comparison of last 3 Asrock h81 PRO BTC 2.0 BIOS (strange behavior) (Read 150 times)

Hello everyone. I'm planning on sending this post to Asrock as well, but I wanted to post here as well to see if anyone has a similar experience.

BIOS 1.20 (2014/7/28) is the BIOS that comes with the board. It's fine but does not support Above 4G decoding and of course it's old, so doesn't contain the microcode patches that the newer ones do. It also has this MOLEX warning splash screen when you install more than 2 cards that you can bypass with a keypress. It is the newer style UEFI type of BIOS that is found in most motherboards nowadays.

BIOS 1.30B (2018/2/27) is the second BIOS update for this board. This is the one I've been using for a few months now and it's been great. It does support Above 4G decoding, and has no splash screen, even if you install more than 2 cards, but the strange thing is that it uses the older BIOS style screen and not the more modern UEFI style screens. This is the BIOS I'll continue to use for now.

BIOS 1.40 (2018/5/21) is the latest BIOS update for this board and has some very peculiar behavior. The release notes signify "Update CPU Microcode", however it does not support above 4G decoding (just like 1.20), has the newer style UEFI screen (just like 1.20), and has that MOLEX warning splash screen when you install more than 2 cards (just like 1.20). The only problem is that you can't bypass the splash screen when you have more than 2 cards installed.

Here is an imgur gallery of all 3 BIOSs. Any users of this board experience the same problems? https://imgur.com/a/2bl2nEd
