Sorry if this is a dumb question. I am getting an unbranded PC supplied without an OS. I have used the BIOS mod without problem on a branded PC that was shown on the screen. For an unbranded PC can I use a loader or BIOS mod. Does it matter what brand is chosen? I found one reference to a BIOS mod saying no SLIC2.1 for unbranded and then select 32 or 64 bit. Any advice (in simple terms) would be gratefully received.
