I am on the 1.00 BIOS the board came with, which is the same BIOS posted on the MSI support page for the board (English). I briefly looked through the MSI forums and didn't see any beta BIOS available for use. I'll look again this evening.
I have heard that some people have been having issues with NVMe drives like mine on these boards. Are you using SATA or NVMe? That may account for some of the difference. Times were done with a stopwatch from the moment I pressed the power button so your startup time @10 seconds from cold boot is definitely faster than mine.
