Thanks johnhc. Sorry about the . I did the tags manually and simply forgot the closing tag that you mentioned.I started with an .ISO image from Microsoft that already had SP2 integrated. I didn't make any non-nLite changes to the image. I'll create another image using the same options but with either OEM Preinstall set to enabled or TEMP set as the normal value. I think that nLite said that having OEM Preinstall set to on prevented use of third-party drivers during the install process (eg having a SATA driver on a floppy) and I didn't see that I myself had a need for OEM Preinstall so I didn't enable it. Think I'll install VirtualBox or similar. Might make this easier to test. oh and the x86-64 thing. What Microsoft did referring to 32-bit x86 as x86 and 64-bit x86 as x64 is a bit odd. I remember years ago reading a post by linus torvalds where he asserted, I think, that x86-64 was the appropriate convention for the 64-bit superset of the x86 architecture, which was first called AMD64. Let me look this up. Ah, here we go: http://en.wikipedia.org/wiki/X86-64 http://lkml.org/lkml/2004/2/23/139 http://kerneltrap.org/node/2466 I'm obviously a bit bored right now. Except for the overwhelming amount of real work that I need to do right now.
