TL;DR: #GRUB assumes that the file system is valid, and might execute arbitrary code if it isn't.

That is a perfectly valid assumption…or it would be if #Microsoft wasn't still trying to ice-skate uphill by pushing #SecureBoot.

News flash, Microsoft: Secure Boot is only secure if the #BIOS is secure, and I'm sorry to break it to you but that is absolutely hopeless.

Now you will ask why I put up a screen cap of Naked.Gun.33.1.3.The.Final.Insult in this thread.

The logic is simple. Because I now have tsc=unstable in my permanent boot options in GRUB, I have achieved playing this 1080p stream on my machine without any hickups of mPlayer!

mPlayer has the gorgeous option of bailing out by itself if you have CPU/GPU/FPU or RAM issues, protecting an unstable machine as my Gigabyte miniPC. Since the switch mPlayer did not have to bail out!

Now the parameters are added permanently at boot
using this UI in my distro. I love editing config files directly. This convuloted manner of editing grub config is inefficient, also unusable in a proxmox or jail ENV where everything is done from *sh

@altbot

The parameters were parsed successfully. Now the unsable tsc clock on this system is bypassed from boot

@altbot

I've just added the parameters to the kernel according to the instructions on the web page; photographed them for our pleasure

Since the people who know about kernel parameter parsing via GRUB, did not see my post and because I forgot to use the AksFediverse hash, I hunted for a answer and am reading this one

This is the massive list of GRUB sub commands that I have to wade through

I have taken a Higher Grade Android to make this photograph and luckily this camera system knows how to capture the Light of the IPS LED panel in Total Darkness.

Compliments of Open Camera Android version

I'm going to include another photograph to give you an indication of how complex GRUB is in comparison to Legacy Lilo

When I press tab twice in Rapid Succession, the whole screen is filled with commands that I can execute within the GRUB sh {command environment}

I literally have to read all the man pages of those GRUB sub commands which give me an indication that they can do what I want, just so I can pass the parameters to the kernel

GRUB has made the distance between the command prompt and the kernel much bigger!

The camera of the Android is utterly failing to focus on the dimly lit IPS Led flat panel screen, but I have still captured a photograph of the command shell of GRUB

I have found the way to add parameters to the kernel at both time from GRUB
I'll make a photograph in a number of minutes
