Dell OEM Windows XP Pro 64-bit (AMD) doesn't work

[Guest XP Man]

I have a Dell "Microsoft Windows XP Professional x64 Edition" (SP1) install cd that came with my GX620. It unfortunately doesn't work when I try to slipstream SP1.

I finally realized why and wanted to post this message so anybody else who googles this problem will realize why.

Windows XP Pro SP2 applies only to *** 32-BIT *** Windows.

I needed the "Service Pack 2 for Windows XP Professional, x64 Edition." It's kind of hard to find on Microsoft, but try KB914961

or http://www.microsoft.com/downloads/details...;DisplayLang=en

It's the same one as for Windows Server 2003 x64 editions service pack 2.

We all have our "doh" moments.
