So, I'm am out of ideas here! I have seen sellers on both eBay and Amazon selling the Asus AiO P1801 with both an mSata and HDD installed, I have purchased a 128GB Toshiba mSata and installed it in my P1801 with no luck. I have read that there are mPCIe SSD cards available how do I know which is which and when I asked a eBay seller about how this was accomplished he stated he used a 256GB mSata and had no issue. I'm lost and frustrated here! In conclusion, I'm trying to figure out if I can get an mSata working in the P1801 or what settings air how I can get this working!?
