Add/Unlock extra second SATA (msata) port in AMI BIOS
Hello everyone,
I have a Lenovo ThinkCentre M73 Tiny PC with a normal 2.5 SATA hdd, I looked at the motherboard which had solder markings and room for an optional msata 1 slot, so I headed online and got a port and soldered it onboard. Then I inserted my msata ssd hoping for the magical upgrade to do its thing, but unfortunately it didn't appear in the BIOS. I noted that in the bios screen it only shows SATA 1 and no other port. So I was hoping if ant of the experts out there can help me out and unlock/add the extra SATA port?

Note: I found the same motherboard (m4500q model) with working msata port on one of the chinese sites online. (
Which confirms that it's possible

PC model: ThinkCentre M73 Tiny
Motherboard: Lenovo IS8XT v1.1

UPDATE: I successfully unlocked the msata port in the bios using the AMIBCP. It now shows that its enabled, however the msata drive is not showing either in BIOS or Windows!??
Can this be due to missing capacitors/transistors for the port (because I compared my motherboard to the one on the Chinese site which had an extra capacitor near the msata port), or is it a software issue?
What is the best way I can test this?
The photos above are from the chinese site, the photos attached below are my motherboard.
Notice one capacitor and one diode missing near the msata slot compared to the photos above.
Can this be the solution????

I've soldered in the jumper and the capacitor.
No success so far.
