Hi all, since my current setup has ACPI on and i', having some troubles with my usb ports, i want to disable it from the installation (in bios too obviously), i usually select automatic, but not this time: so right now im watching the unattented setup page of nlite and i dont know the meaning of the listed types, can you help chose the right one for me please? and anyway im curious about the meaning and differences between them becoz i never understood 'em properly. They are: - ACPI Uniprocessor PC - Advanced Configuration and Power Interface PC (i guess not single cpu) - MPS Uniprocessor PC - Standard PC - Standard PC with C-Step i once used standard and it seemed to work fine, but i really dont know what are the others, anyone knows? another thing...but is there a way to set IRQ in windows?? because i always found the option grayed
