... but now that it comes to it, I have no choice.
Very well, then, let's go with this DOS. Cindori, Peloche, every time one of the thread participants asks a question about DOS, you tell it's possible to make a boot CD or a boot USB stick. Every time you refer to this other thread :

What can we read there ?
Well, sorry to say so, but this description may work for whoever you like, but not for me. Just an example : this guy makes a list how to get a bootable CD beginning with "make a DOS bootable floppy or usb stick". That's not an explanation, that's pure confusion. Do I have to "make a floppy" in order to get a CD ? Floppy disks are a technology from 1980. What the heck is this supposed to mean ? I want a CD because I have no usb stick. If I had one, I'd read the list of things to do in order to get a bootable usb stick. Right ?
I suspect strongly other people suffer from the same extremely abbreviated language, too ... You noticed what AnimeFunTv did a month ago ? He asked in this very thread the DOS question, was told to look what I quoted, and the day after he bought a PC motherboard for his flashing operation, without comment. Coincidence ? Would he have had to do this if there was a chance to understand what this alien guy wrote more than two years ago ? I think not.
Look, what I'm trying to say is you, Cindory and Peloche, are already helping a lot. So please, why not trying to come up with an understandable, step by step explanation to what exactly one must do to get this d****** DOS boot CD ? If you think it is that simple, I invite you to have a look at this bootdisk.com site. There are dozens of options, versions, formats ... For heaven's sake, I never needed to burn an ISO with Nero ! First, as a Mac user since 1992, I didn't ever need to know about burning boot CDs, because if I wanted to know, I'd have bought a PC where those things are necessary ! Second, Nero is a PC program I don't own. Third, I have no ruddy idea what's the difference between a bootable CD and a normal one. WHen I burn a CD, I do it with MacOS, with a right mouse click on the folder in question. This is my level, I'm sorry. And as I said, I'm pretty sure other participants here just know to do things at this level, too, and this is why it can get so frustrating reading citations like the one of the quoted alien guy without hope to understand them if armed only with logic.
So I repeat : please, could you tell me (and others) where to go, which file (available today and not two years ago) to download, how to burn it with MacOs average resources ...
Thank you very much.
