I haven't seen the error before, could you provide more context such as the Bochs guest system and your bochsrc configuration file?

Thanks for your reply! This is my files about,please give me some advice or could you give me your compiled binary and config files? looking forward! bochs.zip

That message isn't a fatal error, it's a seemingly harmless information printed by the floppy controller. It's probably related to the fact that you have a floppy disk enabled in your config:

floppya: 1_44=/dev/fd0, status=inserted

but if bochs.exe is crashing or aborting for you (is it?), there is most likely a different reason. Have you tried attaching to the emulator process with a debugger?
