Okay - that's a new one. Something went wrong in the keyboard code. Can you increase the keyboard debug level by setting the following in src/config.h: #define DEBUG_ISR_09 1 #define DEBUG_HDL_16 1 I wonder if something corrupted the BDA.

The IRQs are probably messed up because the bios tables aren't being copied.
