You have to remove the loader before mod the bios, otherwise at next boot you may have 2 slic tables in memory (1 from bios and 1 from loader) and the conflicts possibility will be very high. The PC may fail to boot.
Hi before I waste anyone's time what does this mod do ? What I'm trying to find is a way to flash the bios on my Dell optiplex 145 so I can overclock my c2d e6600 CPU and speed up the fan on my video card . Is this what this mod does ?
