Hello Victor Milovanov,
To connect an mSATA SSD to an Intel® Desktop Board that does NOT natively support mSATA, you must use a third-party mSATA-to-SATA converter/adapter.
The mSATA SSD drive plugs into the adapter. Then connect the adapter to an available SATA port using a standard SATA cable.
First of all, the DX79TO board is old enough that its BIOS has absolutely no support for NVMe drives. If you were to get it to work (but I am not saying you will), it will be in the Windows environment only; you would never be able to boot from it.
To my knowledge, the people who have been successful have done so with special PCIe cards that,
- Provide a BIOS extension that adds support for accessing and booting from the drive(s) connected to it.
- Include a SATA IC that supports the operation of attached (M.1) mSATA SSD(s) or M.2 SATA SSD(s).
I have not seen a card that (successfully) supported an M.2 NVMe SSD in these older boards.
BTW, there is no POST code 0x64. The BIOS does not use any code in the 0x60 - 0x6F range (because the '6' and 'b' are too similar and caused confusion). Thus, what you saw was likely POST code 0xb4. Unfortunately, according to my cheat sheet, there is no specific operation/event assigned to POST code 0xb4. But, this value *is* in the range of POST codes (0xb0-0xb7) that are reserved for operations/events associated with fixed media (SSD, HDD or SSHD) boot device initialization and configuration. Logically speaking, this is where I would have expected it to fail with a NVMe drive in the picture (which was probably confusing it something fierce)...
Hope this helps - and sorry it wasn't the answer you wanted to hear.
I'm just hoping somebody had already faced this, and was more thorough than I am.
