maybe explain where this code came from because I don't know what program could be modifying VGA registers and then talking to the MIDI interface a few instructions later.

im not the one who has to use 200 hacks and scripts to "fix" my operating system and make it even remotely usable after spending 2 hours installing it and "activating" (""cracking"") it, i spend 10 minutes configuring X11 and keybinds, make some bash aliases (in reality i just copypaste my defaults, which takes one minute) and thats it.

Explain the difference between RPL, CPL, and DPL are and how to sum a register, a register shifted by a constant, and an immediate, stored into 3rd register, in a single instruction.

 №6164

CPL is the current privilege level, DPL is the privilege level of a segment, and RPL is shit nobody needs (requested privilege level)
>how to sum a register
ADD
>..., blabla teach me assembly pls
ADD eax, ebx
ADD eax, ecx, 2
ADD eax, 42
happy now?

 №6301

>nobody cares about RPL
Not caring about RPL good way to get a GPF in ring 3 because you didn't setup the segment registers in the TSS (or other structure) properly.
>doesn't know about LEA
lea eax, [ebx+ecx*2+27]
>ADD eax, ecx, 2
This is an invalid instruction. The only x86 instruction that supports three operands is IMUL.

High quality software you are developing I am sure.

Not librebootable, instant trash

 №6115

>>6092
theyre shittier cheaper ripoffs, but sure a dell latitude is higher quality than a modern lenovo chinkpad, theyre basically equal to early 2000s fagbooks at this point.
especially considering that thinkpads support libreboot and work without blobs
the latitude E6400 is the only model i know of that can actually compete with thinkpads, since its easy to flash (no disassembly), cheaper than thinkpads due to (currently) low demand, and has some very sturdy toughbook-like models thinkpads cant compete with.
consider getting one.

To be fair you can get fucked over even if you think you are getting stuff from repos.

yes, for stuff that matters
i audited X11, the shit in my kernel, and my WM
i didnt audit soystemdick or shit like dbus doe, its way too messy and im gonna put in some effort to get rid of it in the future, HyperbolaBSD whenever its finished perhaps

thats why signatures and hashes exist, every sane package manager will check them by default and will require you to manually bypass them if you wanted to do that for some reason
