|A number of ways. Not sure it can't be installed only not certified is the statement at dell. |
One would be to try to load it, you might need to slipstream the cd to include some drivers or add floppy drive.
Other is use a linux/solaris/bsd distro and then run a virtual machine. Might run as fast as it would normally and support most os what you need.
Might even look at vmware esxi.
"Best Practices", Event viewer, host file, perfmon, antivirus, anti-spyware, Live CD's, backups, are in my top 10
