This is in no way a complete answer

PCI device tree is formed
BIOS loads the MBR
MBR points to the kernel image stored which is then loaded
Kernel boots with one process with pid 1
Kernel imports the PCI device tree and based on PCI IDs loads the corresponding modules.
Now the kernel is able to do DMA by itself (either over disk or network)

After this comes the init levels which I am not really sure about. Here's a skeletal idea.
The first level is single user mode
Then a multi-user mode and a shell is spawned.
Then X is launched if configured.

@longbelly can't you just look it up by yourself and share it back if you want?

@peter159 the point of the question is to see how much you know about a computer. The goal is not to work around the question with rhetoric, but rather to prove you know something about the topic at hand.
