It is GIGABYTE Mother board ,u search in google with motherboard model number that u had mentioned above, u will find the complete information about ur motherboard with picture.
From what little information I could find, your motherboard does NOT provide a CD_IN connector. ONLY the GA-PCV2-DVI version provides the connector you're looking for, while the GA-PCV2-DSI version of the m'board (the one you own) does NOT have the CD_IN connector... wish I had better news than that for you...
Just FYI, you can download a LARGE file (~55MB), which contains ALL of the drivers AND the m'board manual in .ZIP format directly from here:
It took about 17 minutes to download that entire file to my HDD, over a broadband connection, so I can only guess that the server is restricting download speeds...
Once you download that file, you can unzip it and locate the manual (in .PDF format), which is the "PCV2_Series.pdf" file...
In the manual, you will find the information I've provided here on page 12, so you can verify what I've told you...
Good luck; I suspect you'll have to install a compatible soundcard with a CD-IN connector if you really want one...
