I've Modded and installed Win Vista OEM [x1] and Win7 OEM [x3] on my ASUS homebuilt desktops. So, I'm not exactly new at doing this. What I'm having trouble with is getting a firm grasp on how it is done on a Dell laptop. I have a Dell Inspiron 1545 with Vista x64 on it. I want to up it to Win7 x64 OEM. I have down loaded the BIOS and all the drivers from Dell for the Win7 x64 OEM install. The present BIOS on the laptop is an A02. The recommended and d/l'd BIOS is an A14. This is also the BIOS version recommended as the current up date for Vista. When I plug the A14 BIOS executable into Phoenix SLIC Tool 1.36, before loading anything else I get a Dialog box Stating: " Pubkey w48_21.ROM [x1] Marker[2.1][Dell WN09 ] in 49_22.ROM [x1] " After running this in Phoenix, I get the same dialog box when I plug the result back into Phoenix. What I'm thinking is that the Win7 down loadable A14 BIOS is already SLIC 2.1 and does not require modding for a Win7 OEM install and activation. Is that right, or am I barking at the moon again?
