Notes:
1. This signal can be driven by GPIO24 from the ICH8M or as a custom option from Pin 10 on the
Ethernet LED connector at location J28.
2. This pin is not grounded on the Iguana since it can be used to detect the presence of an mSATA
module versus a PCIe Mini Card. Grounding this pin is available as an option on custom boards.
3. This pin is not grounded on the Iguana to make it available for mSATA module detection.
4. This signal drives the blue LED activity indicator at location D11 (upper right corner of the board
as shown in Figure 6). This LED lights with mSATA disk activity, if supported by the mSATA
module.
5. Some PCIe modules use this signal as a second Mini Card wireless disable input. On the
Iguana, this signal is available for use for mSATA versus PCIe Mini Card detection. There is an
option on the VersaLogic Features BIOS setup screen for setting the mSATA detection method.
