back story
even though this is a hell of a challenge (atleast for me), i’ve been able to get some? [really not much] progress for a system like this, people have gotten it on the same CPU… but they’ve always used an older motherboard, and the issue i get currently is 0x00007B, used to get the infamous ACPI one but i guess as said, pressing F7 works justtt fine.
system
my main computer:
cpu: amd ryzen 5 5600
gpu: amd radeon rx 6800
ram: t-force something 3600mhz cl18 (iirc)
ssd / hdd: silicon power a60 1tb / wd blue WD5000LPCX-24C6HT0 (ripped off my now dead old laptop(rip))
before anyone says anything, no, i am not installing this on my SSD. i have this HDD specifically for XP in mind, lol
and now back to the AHCI, device management just declares mine as the good 'ol Standard SATA AHCI Controller.

and here are them Hardware Ids. if anyone has an ahci driver for it, that’d be damn amazing!
p.s.: this is a project for fun, i’m 100% sure my gpu drivers will NEVER work, but i’m gonna have some fun atleast
and, for a tl;dr
tl;dr: trying to get ahci drivers for my ahci controller, can’t find any, if someone could help it’d be great. (and general help for installing windows xp on new hardware)
