NUC8i7HVK上电后启动延迟且无BIOS输入指令

我注意到我的NUC上有几个问题可能没什么，但是看起来很奇怪：
1.当我按下NUC上的 电源按钮和显示器显示初始引导屏幕（以及USB外围设备通电）之间有大约8-10的延迟。
2.初始启动屏幕显示“Intel NUC”和显示屏右上角的几个方块，标签为“Setup”和“BBS”，但就是这样。
没有说明“按F2进入BIOS”或类似的说明 - 除了“Intel NUC”，“Setup”和“BBS”文本之外，屏幕是空白的
以上问题是否正常？
NUC完全可以运行，因此这些问题似乎无害，但看起来很奇怪，启动屏幕不会给用户提供有关如何进入BIOS的指导，并且显示器初始化之间的长时间断电似乎过多
与我用过的其他主板相比。
谢谢！

I've no ticed a couple of issues on my NUC that may be nothing, but seem strange nonetheless:

1. There is a roughly 8-10 delay between when I press the power button on the NUC and when the display shows the initial boot screen (and USB peripherals get powered up).

2. The initial boot screen shows "Intel NUC" and a couple of squares in the upper right hand corner of the display with the labels "Setup" and "BBS", but that's it. There are no instructions that say "Press F2 to enter BIOS" or anything like that - the screen is blank other than the "Intel NUC", "Setup", and "BBS" text

Are the above issues normal? The NUC is otherwise fully operational, and so the issues seem h ARMless, but it seems strange that the boot screen wouldn't give the user some guidance about how to get in to the BIOS, and the long power on delay between display initialization seems excessive compared to other motherboards I have used.

Thanks!
