OPENSTEP Installation Guide What is this?

OPENSTEP was an operating system created by NeXT Software Inc. It served as the basis for Mac OS X after Steve Jobs came back to Apple after Apple acquired NeXT. This is simply to teach and show computer history.
Prerequisites

OPENSTEP 4.2 User for Intel - Download
OPENSTEP 4.2 Developer for Intel - Download
Install Disk Floppy Image - Download
Drivers Floppy Image - Download
Network Driver + Patch 4 Bundle - Download
Parallels Desktop 9+ OR VMware OR VirtualBox (this guide is for Parallels only, however, the files work with the other virtualization programs as well).

Optional Downloads

Network Driver (Standalone for VirtualBox) - Download
OPENSTEP 4.2 Dev Patch (Standalone) - Download

Set up a VM

Create a new VM inside Parallels. Select "Other" as OS.
Make sure to configure the hardware:
CPU: 1
RAM: 64 MB
Graphics: 64 MB with 3D Acceleration and Vsync
2 GB simple Disk
Configure HDD, Floppy and CD like this:
HDD on IDE 0:0
CD on IDE 1:0
Floppy Connected

Mount images

Mount 4.2_Install_Disk.floppyimage in the floppy drive.
Mount Openstep-4.2-Intel-User.iso in the CD drive.

Installation
Preparing the installation

Boot up the VM. When asked to enter something, do NOT enter anything and wait.
Enter the number of the language you want to use. 1 is Englisch, 3 is German.
When asked to erase the hard drive, do so by entering 1.
Now the installer will ask you to insert the driver disk. Do so by switching the floppy image to 4.2_Custom_Driver_Disk.floppyimage. Then press ENTER.
When presented with the drivers screen, enter 7 twice until you can see the entry for Primary/Sencodary(Dual) EIDE/ATAPI Device Controller (v4.03).

Enter 5.
Repeat Step #5.
When asked if you want to load additional drivers, enter 1 to continue without doing so.
You will now see a white screen loading stuff. Let it run. If a kernel panics happens here, make sure the CD and HDD are connected to the correct IDE slots.

Running Setup

You are now entering the setup. Enter 1 to start.

Continue entering 1 until setup beings. This will only format the drive.
Wait until the installer finishes. You will see a progress bar of dots and equal signs. They will fill twice.
Screenshot
When the installer finishes, disconnect the floppy drive and press ENTER.
Screenshot
This step will take a moment.

Configuration

OPENSTEP will now complain about missing drivers. Insert the drivers floppy again and enter 1.
Screenshot
OPENSTEP will boot and load up.
Screenshot
Two alerts will pop up. Simply press OK.
Screenshot
You will see a dialog "Summary of Devices". Do not change anything here. Just save and confirm the dialog warning of an incomplete configuration.
Screenshot
Configuring stuff already can break the VM so don't do it.
In the following dialog uncheck all languages that you don't want. Leave the rest checked.
Screenshot
The installer will now take a short moment to configure the packages. Even though the installer says it's NeXTSTEP, it is OPENSTEP.
When the installer has completed, disconnect the floppy and restart.
Screenshot
In the upcoming dialog, select your preferred language and keyboard layout and continue.
Screenshot
If any dialog appears stating that the floppy is unreadable, simply press Eject and continue with the next part.

The system is now installed...

...but you're missing drivers.

The system doesn't have any graphics or networking drivers, yet. We're going to solve at least the graphics. We will now install Patch 4 that solves the Year2K-bug and introduces a VESA-driver for better graphics. Do not get scared by the number of steps. Many steps are only clicks on buttons.

Click on Disk, then Eject inside the Workspace menu. If there is any complaint about something being unreadable, simply eject anway.
Mount ne2k+os42patch4+vmwarefb.iso into the CD drive (you can eject the installation iso).
Click on the newly visible CD icon.
Copy the contents of the CD to the folder me. You do so by marking all three items and dragging them to me.
Go to me and double click os42machuserpatch4.tar. This will bring up a dialog stating that the file is compressed. Click Unarchive there.
Screenshot
Please be patient. You wil not see any progress. Wait until you see a new file OS42MachUserPatch4.pkg before you close the inspector.
Open /NextApps/Terminal.app.
Type in the following commands:
su
/NextAdmin/Installer.app/Installer /me/OS42MachUserPatch4.pkg
Screenshot
Click Install in the now appearing Installer.
Screenshot
Leave everything at default and click Install.
When asked to confirm that the package runs programs during the operation, click Continue.
When asked to continue even if some of them are installed, click Continue.
When the installation has completed, reboot by double-clicking the NeXT-icon in the upper right, then Log out and finally Power off.
OPENSTEP will now shut down and then tell you it's safe to turn it off. Reset the VM and let it boot up again.
You may read again that the floppy disk is unreadable. Eject it once again.
Run /NextAdmin/Configure.app.
Click on the monitor icon in the top row. In the now appearing dialog scroll down to VESA VBE 2.0 Display Driver (v1.00). You cannot use the wheel to scroll but have to drag the scrollbar on the left. Then click Add.
Click Done, then Save.
Reboot once more.
You will now see a blue/white window while booting instead of the Openstep logo. If this happens, you've installed the driver successfully. You should then get a "nicely" colored desktop.
Screenshot
We'll now change the resolution so you have more space to work with. To do that open up /NextAdmin/Configure.app once more, click on the monitor symbol and click Select in the section Display Mode. Choose a resolution you like but don't shoot too high. I recommend 1152x870.
Screenshot.
Reboot again after saving and tadaa, you have more space!

Screenshot
You're done!

I included the NE2k networking driver but could not yet figure out how to get it up and running in Parallels. If you have any ideas, shoot me an email to openstep@bfx.re. The VMware-file is for VMware users who like to experiment with more than the standard VESA driver.

Have fun running the system that saved Apple and probably made a whole new industry possible!
Additional Notes

The developer image provides development tools like Interface Builder and sample Objective-C code to explore. You can run all the samples by clicking the Demos folder in the toolbar.
