Microsoft made available build 1289-RC1 of Windows XP Pro for AMD x86-64 computers. The download page notes a date of September 2004, but in reality this new version was released just a few days ago.

This build was just released for the Customer Preview Program a few days ago, but testers did indeed get it in September.
So is it worth grabbing it? Has driver support improved much as we get closer to launch?
1289 is rc1 and released to public through cpp. build 1421 was released just one or two days after to msdn subscribers

The Build 1421 is the actual build for the beta tester…
According to http://www.winbeta.org/ build 1421 is for Windows 2003 Service Pack 1, the lastst build of Xp x64 is 1289.
I’ve downloaded it, here is what it is, w2k3sp1_1289_usa_x64fre_pro.iso. It is build 1289 and it was last modified Friday, December 03, 2004, 5:15:52 PM.
Why are they releasing a months old build?
Anyone actually try this out?
I know its beta, but is it ‘dual boot nice’. Could I install it alongside my winxp install with relative assurance that its not going to blow up anything?
The other issue is of course drivers. Anyone know the state of these? Mines a laptop, so who knows what state the drivers are in.

Why are they releasing a months old build?
For the same reasons you get six month old packes new in deian-stable? Because they’ve been determined “stable” after testing (hence the time)?
Obviously this is still beta, but they want to get their releases “semi-stable” so they at least function somewhat on beta-testers’ machines…
So Intel now has the EM64T chips. I’ve been told they are exactly the same, but I keep hearing this Windows is an “AMD64” thing. Can someone just tell me, will Windows XP x64 work with the EM64T?
EM64T is not exactly the same… It’s basically a bolt-on of the AMD64 x86-64 extensions onto the Intel chip. It should work the same so you should be able to run XP64 on it.
Try it and report back.
BTW, I’ve tried two burns of this build and both of them give me a BSOD STOP when I try to boot off the CD to install (upgrade) my WinXP64 beta 1 installation. YMMV.
I’ve done an install and everything went smooth, no big errors, i’ll report back.
EM64T is inferior to AMD64.
They do not have NX bit, and have problems with mapping IO (that can map only to lower 4G not all 64-bit VM).
Newer chips should be fully AMD64 compatible (or maybe some already are?), but with current EM64T, expect trouble.
This caused linux and windows xp-64 to malfunct on EM64T.
