XP/W2k3 x86 on Modern Hardware
daniel_k replied to George King's topic in Microsoft Windows XP@infuscomus Do the following to test the Win8 XHCI drivers on Win8.1: - Create a bootable Win8.1 x86 USB flash drive using Rufus. - Open boot.wim in 7-Zip. - Replace the following files in folders \1\Windows\System32\Drivers and 2\Windows\System32\Drivers ucx01000.sys, usbd.sys, usbhub3.sys and usbxhci.sys -> original, untouched from Win8.0!!! Ported drivers will crash. - Restart and boot from it. Worked just fine here. If USB devices work, your issue is related to the ACPI driver.
