The sheer number of nested/chained operating system-ish layers on a modern computer between your operating system and the actual metal is just stupid.

The sheer number of nested/chained operating system-ish layers on a modern computer between your operating system and the actual metal is just stupid.

UEFI is an operating system. Limine is a bootloader that is more capable than a lot of small operating systems. You've got the IME. The AML VM because God is dead. SMM. Maybe a hypervisor, and then your OS.

PCI, ACPI, AML, DT, UEFI, PEI, DXE...statements dreamed up by the utterly deranged.

STOP DOING BUS ENUMERATION

* DEVICES WERE NOT SUPPOSED TO BE DISCOVERABLE
* YEARS OF pci BUT NO REAL-WORLD USE FOUND
* Wanted to find the addresses of MMIO registers? We had a tool for that it was called "the manual"

LOOK at what computers have been demanding your respect for:

Name (_UID, 0x00)
Method (_STA, 0, NotSerialized){
Return (0x0F)
}

This is REAL AML done by REAL computers.

They have played us for absolute fools.

@rk just seen your sector talk hit YouTube

@rtificial

Hehehe. Not my best work (), but I had a lot of fun with the geographic distribution datasets.

@rk I didn’t know white label was even a thing till hearing your talk. Then I had a eureka moment that explained why I’d see the same dumb ass devices on networks but labeled wrong. Kinda had an idea that something weird was going on.
