There are a few permanent jumpers installed. Motherboard is the HOT-613 Rev 2.0 with the ITE I/O chip U48. All of the pins below are visible in the 1st picture in the thread on page 1.
JP1 - 8 pins, blank no header. (to the right of CPU socket 1)
J34 - 8 pins, blank no header. (to the upper left of CPU socket 2)
JP2 - 2 pins, blank no header. (to the right of SIMM 3&4)
JP3 - 2 pins, blank no header. (to the right of SIMM 3&4)
JP16 - 3 pins, pins 1 & 2 permanent jumpered (just to the left of the BIOS chip)
JP29 - 2 pins, blank no header (right next to IDE LED, this is an IrDA header according to the motherboard manual)
JP30 - 3 pins, pins 1 & 2 permanent jumpered (above empty U30 above the blank alternate ROM socket)
JP33 - 3 pins, pins 1 & 2 permanent jumpered (just below the IDE socket)
JP35 - 3 pins, pins 1 & 2 permanent jumpered (to the upper right of the APIC)
JP38, JP39, JP40 --- 3 pins each, these are bridged between 1 & 3 between the CPU sockets area
I'll try a new BIOS since mine is a very early BIOS, maybe the initial revision.. otherwise that is a lot of jumpers to look at. I may need someone with a dual socket board to confirm jumpers for me, as these are not documented in the manual. Someone please help! 😁
I do have pin headers I can solder in for testing, but don't want to damage anything..
Also -- the Compaq VRM causes the motherboard not to boot, it gets power for a split second, then powers off. The VXI VRM module does allow the board to boot, but the 2nd CPU isn't recognized. Maybe there is a specific Shuttle VRM module? I heard the VRM for this board was made by Raytheon but I don't have a model number. It supposedly had "Skynet" silkscreened on it.
Motherboard manual attached.
