Ok, but what is your Vista dvd? An oem one? If yes, please specify. In my case i have a HP notebook but i'm using a brand new Dell vostro Vista DVD, with the right product key. What about you?
I used a DVD which I downloaded from the internet (usergroups). Not OEM. Vista was activated (emulated BIOS; softmod), but SP1 killed it. Still 13 days left....
It isn't the problem to get the slic in but more of avoiding the cmos checksum failure. When i'm having another idea for a mod I'll come back to you. Maby Yen has more luck, or use a softmod for the time being.
