OpenStep 4.2 on Leopard via Parallels 4

I am glad to say that it is possible install and run OpenStep 4.2 on my Aluminum MacBook (Leopard 7) via Parallels 4. Here are the step-by-step instructions to do so.

0. download the floppy-images from Apple's support area
1. change the extension of such images from .floppyimage to .fdd
2. insert the OPENSTEP_4.2 install CD. It will not be recognised by Leopard... simply ignore that.
3. run Parallels (4.0.3844) and click on the menu File>New Virtual Machine...
4. skip detection
5. select "type: other"... (continue)
6. select "custom"...
7. assign 64 Mb of RAM (this is enough and can be change later)...
8. select "New image file"...
9. assign a size of 2.0 Gb and select "Plain disk"...
10. (I do not know yet how to handle network... I used the default)...
11. I used "Virtual machine"...
12. give a name to your machine (e.g., OpenStep 4.2); in "More Options" you can share it...
13. create the machine... start.

at first it will not boot since you have to
14. click on the menu Devices>Floppy Disk>Connect image... and double-click on 4.2_Install_Disk.fdd
15. click on the menu Virtual Machine>Reset

you may recognise at this point the OPENSTEP boot1... wait for the installer to start.

16. select language and keyboard...
17. confirm installation...
18. click on menu Devices>Floppy Disk>Connect image... and double-click on 4.2_Driver_Disk.fdd
19. press Return

here comes the tricky part
20. select the "EIDE and ATAPI Device Controller (v4.01)" to control the CD-ROM; for, press: 7 return 7 return 6 return
21. do the same for the Hard Disk... 7 R 7 R 6 R
22. continue (i.e., press 1 return)

from there, the rest is as usual:
23. 1 R 1 R 1 R (unless you want to do something fancy)...

The next step is to figure out how to get a better resolution, sound and network... let's try!!
