Well, Im trying to install XP on Modern PC because it has Legacy Boot, why not? so. I first disabled ACPI as it doesnt work thus its not much of a real "thing", now Im with AHCI. I first made it work at installer and OOBE. but in real boot. It makes the 0x7B AHCI BSOD that I fixed in OOBE. And the nLite patched ISO with correct AHCI driver did like open something, make an error and disappear. Need heelppp
