Another DOS to consider for embedded applications is ROM-DOS from DataLight. I've done a few projects with it and it has worked well. I put a single EPROM on an ISA board. The EPROM appeared as a BIOS hook which then loaded DOS and the application from EPROM up above 8 meg in the memory map. Harold Harold Hallikainen harold@hallikainen.com Hallikainen & Friends, Inc.
