My first install attempt failed, too. It stated that the files on the DVD were corrupt.
I blew some compressed air into the DVD drive to clean the laser lens, and tried again.
It's running on this IBM 3.0Ghz dual-processor Xeon MP machine (4 processors hyperthreaded) right now, after I downloaded and installed the Kaspersky v8.0 antivirus software.
So far, it's pretty smooth, but I don't see it being any faster than my XP Pro install on the other hard drive cartridge. I'm only running 2Gb of RDRAM, so maybe 3Gb would speed it up a smidgen. We'll see, I haven't really run the OS through its paces yet, nor do I know what will or won't install software-wise.
I may be a bit harsh on my expectations, because I run a cleaned-up XP Pro, with a lot of features turned off, like Indexing, messaging, etc. I also run Bootvis to make for quicker boot times.
This version of Windows reminds me a bit of my Mandriva Linux, in some respects. Now I'll play with it for the 6 months they gave me on the beta user license...
