You want the Device Instance ID string, not the Device Instance Path as you've shown in that pic. This post should help, sortakinda referenced by bigdogchris above:
Good morning Joe. I don't see the "Device Instance ID string" you mention. Here is another pic of it. I scrolled through all the listings and I don't see any Ven or Dev info.
Well I'm stumped. Did some research into that mobo and can't find any reference to anything "Mega Byte" related as part of the hardware, so... all I can suggest is go to Abit's website and grab every single driver they have for that board and install 'em; one of 'em is bound to fill it out.
I have the same problem but mine just says "Other Device" and doesnt have a Device Instance ID String. Not really sure what the deal is.. Have an ASRock 939Dual-SATAII
