Bit-Tech published a quick look at MSI's Click BIOS
If you buy an MSI board and don't like it though -- the old school BIOS is still supported, just re-flash over it. However, MSI doesn't include any sort of BIOS backup on board, which is a little worrying, and what would also be a good idea is to ship the board with both BIOS' and let the user manually switch between them -- creating a backup, and a safer real time option.MSI's Click BIOS - Evaluating UEFI
In all, we like what MSI has done with a familiar place - the important parts work well and it's certainly an improvement which is what counts at the end of the day. There are some ideas that completely baffle us and are best left untouched or removed by MSI, but generally we just can't wait until it's ported across the rest of its range to boards we really want to buy or already use because the potential is immense!
