SATA DRIVE & a wee problem.

Hi
The problem: the SATA/IDE adapter should enable my bios to see the disk. The bios doesnt see the disk. But it runs a search which takes longer with the SATA disk connected;

I've got a MS 6580 motherboard with uptodate bios from MSI's website;

And a good 80GB samsung SATA HD080HJ;
And a good 120GB 4 yr old IDE barracuda on master;
And a "bidirectional SATA / IDE adapter (plugged it into IDE); it has a floppy cable for power & 2 typical cables for the sata disk

Now: I don't have the producer/manual/ because there was none in/on the wee box I bought it in;


What to do?

hmm tricky
