I can try lowering PcdPlatformBootTimeOut to zero. According to the PCD's documentation, that's a valid value, and on a second look, even PlatformBdsEnterFrontPage() / ShowProgress() support a TimeoutDefault==0. This would even shave off 0.3 seconds from the boot time (without breaking the behavior when the user hits a key on the splash screen). Calling PlatformBdsEnterFrontPage() unconditionally seems unavoidable, according to the advice I got from Eric. Otherwise the OsIndications variable will not be picked up. I considered briefly to look at OsIndications directly in our PlatformBdsPolicyBehavior() function, but that would be very wrong. So, how about the patchset with PcdPlatformBootTimeOut|0 ?
