It's the original ELF format file that was used to generate the binary
file. The ELF file is what is output by the compiler.

Yes. Try it and see!

Choose the "floppy" startup type when building the eCos library.

However, while you're still developing you it's probably better to use
redboot off the floppy, and download and debug using GDB, in which case you
would use the "ram" startup type. You can find the startup type
configuration option in the PC HAL package.
