Built the D54250WYK and it's been working fine for a week. I could get into and out of bios with no issues. Today I updated from bios 0018 to 0022. Now can not get into bios, but can get into windows fine.
It seems like the video output from the NUC is not a refresh rate or resolution that my monitor likes. When I hit F2 at boot, it keeps waking up and going to sleep. I've seen this before when a computer is not outputing a signal the monitor likes. Confirmed this is the issue by moving the NUC to a new monitor and bios displays fine. The monitor is fails to display on is a monoprice 27" It worked fine on a Dell 2407wfp.
Again, it worked fine with 0018, but no longer works after updating to 0022.
Hope that helps someone. If anyone has ideas on my issue, please share.
SeanFl, since the issue started once you flashed BIOS version 0022, can you try using the recovery method and then, install BIOS v 0021 in order to check if the behavior persisted?
Please check the other monitor using BIOS v0021
