First of all welcome ... you should fill out your hardware information in your user profile this way its posted any time you post a message or reply.
Ok So you have a motherboard that supports OSX as the Sound and the Network are supported.
You also have an onboard intel 20 GB mSATA SSD which is ok but rather small in capacity for OSX. This mSATA SSD I think can be upgraded to a larger size mSATA SSD but lets leave that for now.
This mSATA SSD no doubt thaks away one of the SATA slots which may limit the motherboards total number of HDD you can connect and have working.
You may want to have it disconnected and or disabled in the BIOS for testing purposes and use only the SATA connectors on the edge of the motherboard. (Intel one's).
Also your CPU has HD3000 internal GFX and I would use this first to get your system working. THen add the nvidia 220 video card later.
I also recommend that users have an older HDD (mechanical) that we can test with. Such as a 500 GB one.. any old working HDD will work. A used pull HDD from and old computer that can be formated will work. Otherwise you can use the intel SSD as long as this is not the mSATA SSD that is on the motherboard. You need to clear this up for us.
As your system is a Sandy Bridge unit this is a little different that what the Guides mention as they were written up for non Sandy Bridge systems.
You will also need to get from Apple OSX Snow Leopard

A copy or Media from a purchased Apple computer (laptop desktop) will not work as these are restore CD ment for only the hardware they came with. They are not the full RETAIL Copy....
Suggest you find out what version of the BIOS is that you have and post that as well - its good to know.
Good news is that we have your Motherboard in the DSDT section of the downloads and all you need to know is what the BIOS version is that is installed on the motherboard. We use the DSDT for install of OSX as mentioned in the GUides.
Which you can read up on here.

Also if your planing to do a dual boot of this then that needs special attention as well

Ok first step is to fill out the missing information need more details....such as how many ssd's you have or do you have a mechanical HDD we can use for testing.
then assemble
PSS... In reviewing NewEggs customer reviews of this Motherboard Hardware - the intel 20 GB SSD (mSATA) is mostly used for SRT or intel Smart Response Technology. From an OSX standpoint this came after Apple had stopped work on Snow Leo (10.6.8) being the last version of any update for Snow Leo.
SO this may not be ideal for OSX. And even windows users complained about it.... just sayin. Which is why I was thinking you can disable it if the BIOS will let you.
This is one review w similar hardware that you may want to read up on.

). So now I must indentified version of my Bios and download DSDT for this (my MB in F3) Do i need update Bios to version newer (like F10) ? Or just let it there? As i know frome Gigabyte website, my MB has UEFI version (but beta) should i upgrade to Uefi? (As my read, uefi don't need dsdt????)
