There is no SLIC1.0 SLIC is for Vista and yo9u can only have one in the bios at once. There is V2.0 and v2.1 for Vista and W7 respectively. SLP 1.0 is for Windows and is termed simply "SLP"on these forums. Most bios mods here will contain the SLP for XP as well as a SLIC for Vista/W7. They are seperate entities and function is not affected by the other.
