You're welcome. It was buried where it was. Other questions remain.

>> When you do so the Advanced Options (including format) are not be
>> available. The AOs are only available in Setup when you can start Setup
>> following a dvd boot. Therefore you can only do a classic clean
>> installation in a scenario that permits running Setup following a dvd
>> boot (and that should be all the yellow dots in the Matrix).
>>
>> The yellow dots in the Matrix are what I prefer to call migrations.
>> Migrations are where you save all your files and settings, install
>> Windows, reinstall your apps, and then restore your files and settings.
>>
>> Darrel said that he believes that upon entry of an UE pk, Setup runs a
>> compliance check to see if any qualifying Windows installations exist on
>> the system that qualify for upgrade pricing and based on that does one of
>> the following:
>>
>> (1) If there is an XP edition that can be upgraded to an equivalent or
>> higher edition of Vista then you get the message to restart and run Setup
>> from the XP desktop. The upgrade option will be enabled when you do so.
>>
>> (2) If there is a Win2k, XP Pro x64, or version of XP that would lose
>> functionality (XP Pro to Vista Home Premium, for example), then Setup
>> continues without requiring running from a desktop. What you get with
>> (2) is a migration. The upgrade option would have been disabled if you
>> had run Setup from the desktop.
>>
>> (3) If none is found you should have purchased a full edition.
>>
>> If (2) holds true for all the yellow dots, it would mean that you can do
>> a classic clean installation of Vista as long as running from the desktop
>> is not required because (a) the legacy OS is not running (and therefore
>> the system drive can be formatted) and (b) the Advanced Options are
>> available when booting with the dvd.
>>
>> Also, if (2) holds true for all the yellow dots, it would mean that a
>> Win2k or XP x86 user could migrate from x86 to x64 with an UE pk by
>> booting with the x64 dvd instead of the x86 dvd. That will be very
>> welcome news indeed. It also explains how the process works for XP Pro
>> x64 users when using an UE pk to migrate to Vista x64.
>>
>> It appears that Darrel's and Carey's statements a few weeks ago that
>> booting with a dvd and entering a UE pk required restarting the machine
>> and running Setup from the legacy desktop were ONLY applicable when
>> upgrading XP x86 to Vista x86 and only then if a loss of functionality
>> would not be involved.
>>
>> Until Darrel's reply yesterday I had not seen a single first hand report
>> of any attempt to use an UE pk in one of the yellow dot scenarios.
>> Darrel was very gracious to take the time to do it for us because I don't
>> think it was in his job description.
