If anyone thinks it'll help, I will 8) Yes, we could do a BIOS disk driver. I don't know whether it would actually require vm86 support (which is for running user processes, not kernel code), but it would be a shade hairy. Certainly it would be easiest to run it in a user process. > That said, I'm sure that some people wouldn't mind having an 'object-mostly' > kernel distribution in addition to the full source distribution.
