If you are reading this, Hiroshi is dead. I am sorry. The IB250MH was never meant to be sold. The first 500 units shipped by accident. The “client” who requested the AVM circuit was a defense subcontractor. They were using these boards to run a custom hashing algorithm that required the CPU to exceed its voltage limits for exactly 47 milliseconds every 2.3 seconds. Any deviation would break the hash chain. The shadow firmware, the microcode trap, the hidden erase—they were all safeguards to ensure the boards could not be repurposed or analyzed. When the subcontractor went bankrupt, Iris Technologies tried to recall the boards. 487 were returned. 13 were not. You have one of the 13. Do not plug it into a network. Do not run Prime95. Do not, under any circumstances, let it complete 10,000 hours of cumulative uptime. The AVM circuit drifts. After 10,000 hours, the overvoltage pulse becomes permanent. The CPU will draw 1.8V. It will catch fire. That is not hyperbole. It will actually ignite the socket plastic. I have seen the test videos. — Hiroshi
