That's what I mean, up to a certain degree. I had always been a DOS programmer, and felt contempt for the MS GUI. Then slackware 2.2.16 came to my hands in a form bootable from DOS. But I wanted the BIOS to directly boot linux. And I achieved this goal. Finally one day, I discovered, within the software I had downloaded, something called Gnome. And I used it to read PDFs and the like.
I still have DOS 5.00 in one partition together with the user's manual, which certainly is a book. He won't object to anything I'll wish to do to the machine.
