I was reading slashdot today and found this article: http://blog.ksplice.com/2010/05/scalable-day-to-day-diskless-booting/
I remember having tried to do this in the past with an openfiler installation and an atom box, I ended up getting frustrated and moving on but this sheds a lot more light on how the process works and how to get it working. It’s kind of a dream of mine to be able to network boot a diagnostic distribution of Linux without having to worry about the HDD at all.
After much searching I have found the answer. You can convert an Avast 4.8 Professional Edition Key to an Avast Profession Edition 5.0 key here: http://www.avast.com/resend-license.php
Recently I was attempting to install a new copy of Windows 2008 R2 Standard Edition on a customer’s ESXi machine. Although I was currently running many different operating systems on the server, I was surprised to see that I could not install 2008. I received the error “0xc000035a Attempting to load a 64-bit application, however this cpu is not compatible with 64-bit mode”. After about 10 minutes of troubleshooting I realised that the problem was not in Windows 2008 or ESXi but rather in the Dell System BIOS. For some reason dell ships their servers with Intel VT Virtualisation Technology turned off! ESXi is unable to run 64bit operating systems without first turning on VT technology. I’m surprised I missed this, out of some coincidence all of the operating systems on the machine are 32-bit. That seems a bit perplexing to me that by default Dell disables this on their servers, it seems like it’d be a no brainer to turn it on. Perhaps for security purposes? If you have an answer, let me know in your comments!
