When was the last time that you ran
`dmesg|less` on your linux system?
You **NEVER** did?
You dont know what you are missing my POSIX dweller!
Look at the awsome input to your brains!!!
Of course you should first run
`man dmesg` since you should not trust a command which uses sudo from a stranger on the internet
https://www.man7.org/linux/man-pages/man1/dmesg.1.html
<< dmesg - print or control the kernel ring buffer
Yes on debian based machines, for some odd reason you are not allowed to run dmesg anymore as a regular user, so I run
`sudo dmesg|less`
Now you know what dmesg does, run it and learn to the bit, what happens on your linux machine when you cycle through the POST sequence
