Greeting from Spain.

I have a Q1900-ITX mobo (without the B) which is starting to fail.
So I bought another one - which I thought was the same, but it has the B and only has two SATA ports.

I have four disks.
So I bought a port multiplier. ADP6SAT-J01, with the JMB321 chipset.
The BIOS does not seem to recognise it, and only sees the disk connected to the onboard SATA port.

I'd like to know:
- Is the BIOS supposed to see it?
- If it is, are there any specific instructions it needs?
- Any other possible solutions to have the four disks working with it?

Thanks.

D.
