This is a MS DOS specific problem because there, the kernel is 2 files.

Almost correct: You can put command.com options in config.sys to tell
it that autoexec.bat is at another location in FreeDOS command.com :-)

As far as I know, that is intentional. C: by definition is the first
DOS partition on the first (according to BIOS numbering) harddisk :-)

I think this is intentional. It would be interesting to know if the
kernel can be configured (with FreeDOS SYS, you can patch some flag
bytes in FreeDOS kernels) to use the boot drive as C:, instead of
the BIOS 80h drive. After all, the boot sector can pass the number
of the boot drive to the kernel using registers, so it could work.

The FreeDOS kernel is only one file, so yes, it is completely loaded :-)
