alt Hacker NewsThank you for noticing (and reading at all). We'll try to fix these asap. "INB" is a genuine mistake, "PC/AT" should be "PS/2" and "discreet" is a translation error.
Some Xeon chips have additional DMA controllers "onboard".
No AI was used, each mistake here is handmade with love and 100% organic :) We wanted to give a decent (but not too deep) historical overview, however first and foremost we introduce new vector to conduct the attack.

Generally speaking, PS/2s did not have a PCI bus either, although some of them did have an ISA bus.
(Both ISA and PS/2 microchannel would allow busmastering of exactly what your article describes, though, so the point might as well stand - for that matter, so would other buses like EISA and VESA local bus.)

Thanks for responding! Welcome to HN!
I write long form text posts as well, so I appreciate the format. It just had a number of things that didn't seem quite right to me, being in similar deep technical weeds.
Now try the attack on Qubes. ;)
