The old one will still be there too. SLP1.0 You can have many SLP 1.0 strings at one time. The tool puts the SLP strings at addresses not often used by OEMs..so if it has SLP fom factory, it will be the same after flash.. If you have ASUS_FLASH from ASUS, and a modder adds Hewlett-Packard to the bios, you will have both.. If it is modded to add the SLP ASUS string, it will absolutely be ASUS_FLASH....
Thanks domatlapuk & 911medic. I kind of got that impression form searching, but still wasn't 100% sure.. Figured it better to ask now, rather then be surprised later.. That's all I needed to know... Thanks again..
