Hi Thomas,

Thanks for your reply.

The Atom processor is of the Bay Trail type. Yes, 32Gb is the entire storage. I opened the Mini PC, which by the way has a form factor similar to typical routers, and saw that the storage looks like a USB drive embedded on its motherboard.

Regarding order printing before saving, since I myself developed this, I made it a point that both header and child records are SAVED (wrapped in a transaction) before I print the order. Seriously, this what really confounds me. How could the child rows 'escape' the transaction being save in the server?

>>The app starts up fine, but during several instances, there appears to be rather sluggish response. Twice, a "POS is not responding" appeared and hangs up this mini PC. What is worse, was there was an instance wherein a string of orders have been printed out by the receipt printer, but was missing in the database! (Only the Sales header was saved, the child details went missing).
