Quote from: Anonym on May 11, 2020, 16:00:08MSI Max series are the only B450 boards to have 32MB flash. Also I just checked and all motherboards with dual BIOS feature have 2x16MB or 2x32MB flash, none of them are sharing a single chip.Quote from: kaspark on May 11, 2020, 15:00:15B450 Tomahawk MaxThat's a whole different matter. MSI clearly states the MAX line has a 32MB flash to fit their larger UEFI GUI alongside the latest AGESA updates (where other boards would have a 16MB chip). MSI is also the one with the smaller flash on the latest supported chipsets.
Sure, there are always exceptions to the rules. However, sounds more like you should ask MSI about their creative engineering than anything else. There's nothing keeping them from supporting your boards, as others have done in the past (i.e., Asrock).

I'm also not finding anything about dual BIOS on this board, it has a flash BIOS button for updating BIOS without CPU inserted or unbricking after a botched update.Quote from: kaspark on May 11, 2020, 10:06:59Those 32MB in older motherboards are actually "hardwired" to be 2x16MB, as that is a fail-safe mechanism to avoid bricking the board in a bad BIOS update. While perhaps not impossible, I would say it is unreasonable to demand the removal of an advertised anti-brick feature, which may have been a deciding factor to purchase that board.
Except there are X470/B450 mobos with 32MB flash and X570 mobos with 16MB flash.
Cannot comment about the X570 boards with 16MB flash. The AMD guidelines likely stated the need for a 32MB flash, so it is up to the mobo manufacturer to get out of that mess.
