Not sure what I did, but it went away. The floppy device now sort of works for read-only: P00>>>boot dva0 (boot dva0.0.0.1000.0 -flags A) block 0 of dva0.0.0.1000.0 is a valid boot block reading 81 blocks from dva0.0.0.1000.0 bootstrap code read in base = 200000, image_start = 0, image_bytes = a200(41472) initializing HWRPB at 2000 initializing page table at ff56000 initializing machine state setting affinity to the primary CPU jumping to bootstrap code However, the emulator segfaults at that point. My debugger shows that the crash is in CAlphaCPU::vmspal_ent_dtbm_single(int flags). Could be a threading thing, as well, since the last message on the console is: *** IP interrupt set for CPU 0 from CPU 0(@ 110d5) It doesn't work in any guest OSes at this point...but it doesn't hang them either... I'm going to hold off doing too much more until the CDisk class gets straightened out. Out of curiosity, how are you planning on handling removable media? It seems like we'll need an out-of-band way to notify es40 of a disk change.
