Network-boot a Parallels Workstation client

Warning: Geeky stuff ahead!

The Parallels Workstation virtual machine software for the Intel Macs has a BIOS which doesn't support network booting.

I wanted to simulate an LTSP workstation, which would boot over the network from our Linux server. Here's how I did it:

On the ThinStation project site, I found a link to a Universal Network Boot package - a zip file containing disk images for floppy, CD and HD.

From this I grabbed the ISO CD-ROM image eb-net.iso and set up my virtual machine to use this as the CD instead of the physical CD drive. I also configured it to boot from CD first, and, for my purposes, I removed the hard disk from the config as well.

Sure enough, it boots up just fine and I have an LTSP terminal in a window. Much easier for experimentation than rebooting my embedded device all the time.

The Seven Screens

I was over at my old company, Newnham, today, and they were setting up a cool demo.

What's particularly cool about this, for those of you not familiar with Newnham, is that the machine driving all these displays is just an ordinary PC with a regular single-output graphics card in it. It could have been a laptop.

If you're used to dragging your windows around a screen, it's much more fun being able to drag them around the room!
