How do I reformat 486 DX hard drive and be able to reinstall DOS 6.2 and Microsoft Office -no internet access?

Question

I am getting rid of the computer to someone I don't know and want to make sure that they cannot retrieve any of my files, however, I do want them to be able to use the computer and the programs I have.

Answer 1

Take the original install discs for Dos, boot up with it, type FORMAT C: /S
Then look on the floppy (DIR A:) and see if there is an INSTALL or SETUP program, run it

Same for the other applications, install from disc.

Good lick trying to sell that antique though . . .
