Title: How to boot to DOS from diskette reading HDD config?
Post by: MIRKOSOFT on August 30, 2019, 07:31:58 PM

Hi!

I'm using MS-DOS 7.10 and want to boot into by floppy disk.
I tried to modify AUTOEXEC.BAT on floppy to use commands and software from harddisk, but it is always using floppy commands and software.

How is possible to boot DOS from floppy but reading harddisk config?
I know that is possible to fix booting from HDD by SYS C: command, but I need to leave on HDD GRUB and untouched.
Or: is possible to fix GRUB that will correctly enter DOS?
It always reports error on item created for DOS.

Thank you for understanding.
Miro

Setting up a fully working DOS system will give you great appreciation for how far computing has come.  For old-timers, it will be a walk down memory lane; for youngsters who've never used nor even seen DOS before, it should be quite an eye-opening experience to experience first hand both how primitive DOS was and yet how capable it could be.

Good point.
For anybody that wants to do DOS programming and does not want to pay for it, he ought to consider using a Free version of DOS.

He just has to add this line to the autoexec.bat on the boot floppy, assuming he has a standard MS-DOS layout on the C: drive, with system executables in C:\DOS:

PATH C:\;C:\DOS

Really, this is so elementary that a child could find it out.
