Hi

 

I have installed a HP Thunerbolt PCIe card.

 

In the bios a new option appears : Device Options > Thunderbolt .

 

There a 4 addition options to choose for the Thnuderbolt Option.

 

1) Unique ID

2)One time saved key

3)DP++ only

4)Legacy Mode

 

F1 tells me nothing and the manual has nothing either about what these setting mean .

 

Can someone help please

1) Unique ID, does exactly what the name says and should allow hotswap devices

 

2)One time Saved Key, (Applies to Falcon Ridge devices only) allows Thunderbolt host controller to differentiate between many of the same type of device

 

3) DP++ only, use the card as a video device only (Display Port)

 

4)Legacy Mode, allows any Thunderbolt device to connect the host

 

 

if you could,  can you please give us a pinout of the GPIO cable that connects from the card's 5 pin header to the motherboard's c25/c26 header

Hi 

 

thanks for that , I wonder why those options aren’t in the thunderbolt settings in task manager instead .

 

i guess unique I’d would be best for a audio interface then.

 

 

now you want a pin out of the c25 + c26 Cable ? No problem ? what do you mean exactly ? Do you want me to tak a photo of them close up ? Or is there a color code you want for each pin ? 

 

Let me know now and I will do that for you today .

 

thanks

we need a pin to pin description, so we can make the cable as hp does not sell it seperate anymore

 

IE- pin 1 on card to c25 pin 2

 

or, several clear photos showing  the cable connections

Hello 

 

c25 is 1 Pin + 1 wire with 2 loops so easy 

 

c26 is 3 pins + 3 wires with 2 loops , but the 3 wires are the same color and are shrink wrapped so unless you can tell he how to check with multimeter I can’t tell .
