me holding a gun to the x86 boot process: tell me the name of god you archaic piece of shitx86 boot process: can you feel your heart burning? can you feel the struggle within? the fear within me is beyond anything your soul can make. you cannot kill me in a way that mattersme cocking the gun, tears streaming down my face: I’M NOT FUCKING SCARED OF YOU

Everyone knows that x86 still comes up in real mode, right? Ha ha foolish humans x86 comes up executing microcode that loads a signed code module out of system flash, verifies the signature, and runs it, and that sets up cache-as-RAM and verifies the signature on the firmware boot block, and it's running in protected mode, so it actually switches *back* to real mode before passing off control to the firmware because (bong noises)

@mjg59 I felt this viscerally, and I haven't dealt with the boot process since 32-bit protected mode. I'm sure no work has gone into simplifying it since then...

turning a big dial taht says "Compatibility with 70s design decisions" on it and constantly looking back at the audience for approval like a contestant on the price is right

@mjg59 but it's not *real* real mode, it's *big real mode* because obviously you want that and actually even more than that on any halfway modern CPU it's actually long big real mode

@mjg59Saw this toot out of context, and clicked it wondering if it would be about 1) Microsoft operating systems, 2) urban planning zoning requirements, or 3) BART rail expansion.Close enough to (1) I guess.

@mjg59 It depends. Were they Dieter Rams’s 70s design decisions, or Ettore Sottsass’s?

@mjg59 you forgot the bit where the 486 (or was it 386) embedded in the GPU boots Minix first

@rneugeba that's not actually a strictly required part of the boot process

@mjg59 somewhere I read the baseband for iOS includes an x86 cpu of some sort

@mjg59 I thought at least Intel CPUs have a Quark x86 CPU that brings up the main CPU. Now the question is, does Quark start in x86 mode?

@mjg59 I wonder who knows and understands more... Intel and the deep inner workings of its CPU hardware, or Microsoft and the deep inner workings of its OS.Both seem to be layers of history on layers of ever increasing abstraction.

@crawshaw @mjg59 I'm pretty sure it does that every time I try to enter the setup mode of a particular extension controller (what, you thought booting via PXE does not require any configuration? Oh...), and the various layers upon layers of pre-boot code decide that, just this once, this particular part of the boot process will take 0.0053 seconds.
