I finally ordered the card nanofrog found on ebay.
A german online shop sells them for 20. Twice as much as the original price from the ebay reseller, but still pretty cheap.
I'd seen it on the German eBay site, but it was more expensive there for some reason (different seller). So I linked the UK site, and presumed shipping was possible (not listed as NO, such as Italy).
I hope it works with my external enclosure.
What enclosure are you using?
Maybe I can also connect my internal Windows drive to it and place it in the lower optical bay.
Yes. The BIOS emulation will kick in from the EFI firmware, and allow the card's BIOS to boot the disk.
But IIRC, you have an '09, and it's not necessary. Those can boot Windows off the ODD SATA port that's available for the empty optical bay.
Unfortunately I am still not aware of what I need to get power for a additional 2.5" drive in my lower optical bay.
DIY would be no problem, but what adapters do I need to get two power cords from the combined SATA connector?
Assuming you've an '09, here's one way.
1. Get a
Backplane Extension Cable
2. Get a
SATA power cable
3. Cut the Female end off of the SATA power cable, and splice the Male end to the power connections on the Backplane Extension Cable.
Power, and no modifications to the system that will void the warranty. Not expensive either, though the cost of the cables are likely to differ for you, given your location.
gugucom found a smaller adapter that can also work there in Germany. A bit cleaner, but I can't recall the source. But there is a link in MR somewhere.
