When i upgraded, i just removed my 8GB drive and and replaced it with a brand new 120GB drive (i did not lock the HD).
I put it in slayers to format, install dash and apps.
Slayer installed the original MSDash with the install.
As long as i have the chip ON,
MSDash does work.
So i dont know what jack2004 means by the above post

.
It is the MS bios that won't work with an unlocked HD, the MS dashboard will work fine with an unlocked HD.
