Nerd question of setup disks

by cowdoc6 / February 6, 2010 1:34 AM PST

This is a "how do they do that" question. I recently got a new printer. I use an IMac with "Snow Leopard" and Parallels running Win XP. Never mind why the Parallels but just focus on the 2 operating systems. When I place the installation disk in under Snow Leopard, I see in the finder an installation program and a Manuals folder with installation and usage information. When I insert the installation disk under Windows, I see setup files, a whole bunch of program files, and a Manuals folder. With either OS, I don't see the other OS's files. How do they do that?

Do you mean that some OS details are not showing up?
by macnerd10 / February 6, 2010 3:57 AM PST

At least for Mac part, the OS comes as a package. There is a special program "Pacifist" that can open the package and there you will see "other OS files". Don't know how does it look like under Windows. Guess, the installer disk was not meant to mount under that OS.

I think he means that

when on the Windows side, using Parallels, the only things he sees on the driver disk is Windows stuff. None of the Mac stuff is visible.

Conversely, when on the Mac side, none of the Windows stuff is visible when he opens the disk.

It's a good question and one, of many, that I do not know the answer to.

I do know that if you copy Mac and Windows stuff onto a regular CD/DVD, the contents of the disk are visible no matter what platform you view the disk from.

I think we are both confused

The OP talks about installation disk. Therefore, it should not even run under Windows. What they don't say what is this disk installing. Incorrect info, I guess...

I wonder, he says, scratching his head,

if the OP will ever clarify the original post.

I don't think he means "run" so much as what he can see when he "opens" the disk.

Oh well. Enjoy the game today.

files on printer disk
by cowdoc6 / February 7, 2010 5:30 AM PST

The printer disk is meant to install driver files for either Windows or Mac machines. So yes, it is meant to be used with either OS. But regardless of which OS you are using, you only see the files pertaining to that OS. How do they do that?

For Mac OS you may not even need that install disk: most likely, pinter info (PPD file) is already installed as part of OS X. Just open print and fax in the system prefs, click add printer (it must of course be connected and switched on) and it will find it. Very easy. In your case, you may only need to install the Windows part if you need to print from it.
How do they do it? Could be just file formats that may or may not open under one OS or the other. If you open the disk in Pacifist in the Mac OS, you will see all contents, most probably.

I don't know either but,

the clever part is that regardless of what OS you are viewing the disk under, you cannot even see the files that relate to the other OS.

Neat trick.

Almost, but not quite, as good as the one employed by Disk Warrior where it had up to 5 different versions of the Mac OS on it and it would boot your machine with the one that your machine would support.
Any Mac user with experience will tell you that it is not possible to have more than one "Blessed" System folder on a disk. Now that was a really neat trick. Happy
