Hi guys, i'm in the same situation with a DIH61R Palm Beach M/B extracted from Optiflex 390.
Someone have original front i/o cable and can post photos ? i want to try to emulate other dell pins to cancel "front i/o cable failure, press f1 to continue". Or someone can have complete pinout ? i'm pretty sure that unusued pin is just for this !
Thanks and excuse my bad english
The dell forum is not the lazy tech reverse engineering Forum. The 390 front panel is Totally Different from the Vostro or the Inspiron 620.
This particular board is the SFF F6X5P board and front panel power on is NOT 2 pins nor is it a board.
