I just cannot thank you all enough! Firstly, all the 3 bios mods work to activate the WHS OEM install. At first, I tried the dell mod. I thought it did not work. I requested the HP & IBM mod. I installed the HP OEM and I thought once again that it did not work. Same with IBM. But I have been a fool! All 3 bios mods work! I was applying the vbs script and not rebooting to confirm the activation! Once I reboot, all were activated! I used the WHS OEM disc downloaded off the net and applied FixedBit's script to create DELL, HP & IBM OEM discs! Just to confirm what a fool I have been, I did 3 installs and I was proven to be a donkey! All the 3 mods work on my A8N-SLI Deluxe! So offon7544, thanks a ton!
