I know this thread is a little old but it is the only information that I have been able to find that is close to my problem.
I have a few HP 820 G1's that have a 500GB spinning disk and a 32GB flash card and I have not been able to deploy to them at all with SCCM 2007.
I have imported the sata drivers and created a new TS just for this model while testing and I have it set as shown in the screens below follows.
What I have noticed is that when booting with the HP image it only shows one drive as it is in cached mode. If I push the TS to it then it partitions it, names the drive (and i think formats it fine) but will fail the TS (unable to find a log for it).
I have the BIOS set to legacy (comes like that) and the Msata is set to allow boot.
I have tried every possible combination i can find but have no idea what the hell to do.
Would anyone please be able to help me with this?
