Hi!
I'm sorry for delay.
It is drive with MS-DOS 7.10 on first partition.
SYS C: rewrites boot sector and I want to leave boot sector untouched (it was configured for second OS - OSX86, I know, you maybe don't believe, but works).
I need to start from floppy for this reason:
1. boot of OSX don't recognizes DOS, it is visible only as Foreign OS.
2. DOS from floppy starts, but it is req'd to run autoexec.bat again after DOS boot to have environment active.
3. floppy always runs autoexec.bat from itself, I need to switch to use autoexec.bat on C:\
