[MinnowBoard] Problem with i2c on windows 8.1

Only controller 6 and 7 are routed out, so I am not sure how one would use the others - they are not routed on this board.

6 & 7 is ACPI numbers, same controllers numbered 5 &6 in PCI.
Windows 8.1 drivers for I2C work in ACPI mode if there a need to use them.

Best regards,
Ivan Rouanov.

Hi,

The missing SIO functions has to be enabled. The I/O pads for the missing functions has to be reconfigured if they are used by other signals. You need access to BWG (Bios Writers Guide) and the EDS documents. You need NDA with Intel to be able to download these documents.

BR,

It seems that problem is somewhere in firmware since firmware for Intel CRB boards on same settings doesn't have problem, all seven controllers are visible.

Out of curiosity, why would you need the other i2c buses visible?
(Assuming that the i2c interfaces you refer to as 6 & 7 are the low speed and high speed expansion header i2c interfaces.  It's hard to tell on that as everything refers to them slightly differently)

Subject: [MinnowBoard]  How can I set MAC address in EFI shell!?
Message-ID: <03c701d0bb35$a3c76940$eb563bc0$@tekmagic.net>
Content-Type: text/plain;	charset="us-ascii"

Somehow my MAC address on one of my minnowBoard MAX's got screwed up.

Does anyone know how to write a new address into nvram (or wherever it is
stored) using the EFI shell?

I am using latest 0.81 firmware.

While on this topic, how is the MAC address initially created during manufacturing (is there some utility the factory runs to set the MAC address for each new minnow board produced)? Also where exactly is it stored?

My firmware got corrupted (so I "bricked" this board) and had to use my DediProg SF100 to write a new (0.81) firmware to the flash chip. After that it boots fine and everything seems back to normal but somehow my MAC address got screwed up in the process.

I own a number of minnowMAX boards and have noticed that the MAC address is normally "retained" even when one completely erases and re-writes the flash memory chip (using a DediProg SF100), so this says to me that the MAC address is not stored in the same flash memory chip that contains the firmware/BIOS.

Would like to learn more about this...

THANKS!

Gerard Bucas
