Can I trick the Unix based OSX so I can run my DOS/Windows 3.x emulator
|
|
| Bible John 2005-10-01, 5:54 pm |
| On my Performa 6360 I had Virtual PC 1.x which would only work in OS 7.
It was installed on a Zip disk with a OS 7.x system folder which I used
to boot into and then run DOS 6.22 and Windows 3.x for fun. No its
really just for fun. For real PC work I use my Windows 98 laptop.
My understands are that Mac OSX cannot boot USB zip disks, nor boot into
any os prior to X for some reason. Unix oses do not like booting from
anything but hard drives I was told.
I do not understand why Apple chooses to do this, while most PC's can be
booted into Windows 3.x/DOS on modern machines using partition magic or
http://www.vmware.com/.
Okay so is there some Unix command or way to trick OSX so I can run this
Virtual PC version with my Windows 3.11/DOS 6.22 emulator within Mac OSX
classic mode?
Thanks,
John

Not being able to boot from USB Zip disks has ZERO to do with OS X,
only with the hardware support in the computer itself. Similarly,
various models can't boot into anything earlier than (a specified
version of) OS X because those OS releases don't have the
device-specific initialization and boot information -- this is the
reason that, well before the day of OS X, INITs had to be included to
allow different versions of System 7 or OS 8 or 9 to boot on a new
computer model.
In answer to your VPC question, the answer is "No".

Actually, that's not quite true, because of a technical quirk in OS X.
Some computers, such as the "Quicksilver" G4 computers, are indeed
capable of booting OS 9 from a USB device--but they can not boot OS X
from a USB device.
This is due to a weirdness in the way OS X handles USB device drivers.
Early on in the boot process, as OS X loads and initializes its basic
device drivers, it resets the USB bus. This has the effect of
dismounting the boot USB volume early in the boot process--which, as you
can imagine, causes the boot process to fail.

You can't boot into 9.x on currently shipping hardware either.

Being picky, it should read "System 7". It was at a later time Apple
switched to call its OS an "OS".

Don't trust hearsay. You _can_ definitely boot from other
devices. But, of course, it differs and depends on the specific OS and
the hardware.

I guess, you want to say, that you do not want to acquire a newer
version? Well, at least these come on CD and provide no problems at
the installing level. At work, I am running Virtual PC version
5.something and installed dos from a boot CD. This version is also
smooth enough to boot from disk images. You simply have to assign this
image as boot device. I don't know if the old version of Virtual PC
provides this feature.
Besides VPC you have other options. One of it is dosbox. See
http://dosbox.sourceforge.net/ There is, besides others, also a OSX
port. It's not perfect but allows you to run a lot of old dos games.
Perhaps QemuX (OSX interface to qemu) might be an option. Qemu is another
open source PC emulator. See http://fabrice.bellard.free.fr/qemu/
