No, MSI SLP String can't be added to the Proper Location on an MSI Bios. You only need SLP String if you want to use XP.
Ya, I know it.... Oops, I dont know it.... can I add HP SLP string in the modded one by andy's tool???
Yes, Just click Cancel on the Popup about the NEC SLIC and use SSV2 Method to add SLIC and HP or Dell SLP.
