After reading this commentary on why the bandwidth was severly hampered, I made the connection that an optical drive that I thought was failing had inadvertantly reverted to PIO mode and I was able to remove the device, re-add it and get it back to proper DMA operation, thus saving me some cash.
Just to let you folks know, it looks like the recent http://www.apple.com/support/downloads/macpromid20...">Mac Pro EFI Firmware Update 1.0 from Apple also fixes the problem permanently, according to a post on http://www.macintouch.com">Macintouch. (Look under the Wednesday "Notes and Tips" section.) That update seems to be introducing its own problems, though, so YMMV.
Has anybody tried the following steps instead of re-installing (I don't have a macpro to test on so I cannot try it):
* Install XP SP2 normally.
* Download Intel's 5000X chipset drivers and install them.
* Download Intel's 631 xESB chipset SATA drivers (version 15/05/2006 7.4.0.1 005) and install them.
* Re-enable DMA using the steps listed at this link: http://winhlp.com/WxDMA.htm">http://winhlp.com/WxDMA.htm
Would you do a Tulsa review sometime? Just like sometime back you compared a Paxville 4P with an Opteron 4P. It would be great to know how much life Netburst still has in it. Thanks.
I've a serious question... does anyone here know or have any experience in using Windows PE on a Mac? I'm imagining using the drivers burned into the Boot Camp CD in a PE image, perhaps even a (gasp) Vista PE image.
Then place said PE image on a USB key, and you can boot any up to date Intel Mac into PE, right?
Since these systems use EFI to boot, is overclocking even possible? Are there EFI tools in the public domain? Can you do it while in BIOS/XP mode?
It appears Intel really made these processors with wide speed margins and it might be interesting to at least get the standard 2.66 processors to 3 Ghz.
I converted the web page and re-posted it about half way down. You don't need the "spyware" removal stuff if you don't want them. There are other remarks earlier on how to fix other things in the thread (sound).

Followed the instructions, worked like a champ.MemberSince97 - Thursday, September 7, 2006 - link
Hi Anand, I was curious if your guys were going to a performance review of RC-1 vs XP.Take Care, Bob

Hi.,The Dot Mac account met with severe bandwidth restrictions.
The updated website address is:
http://macprojournal.com/">http://macprojournal.com/
This has the Mac Pro / SATA / XP fix fully documented online.
Thanks.

My Update Pack is a must, however :) :Pplinden - Tuesday, August 29, 2006 - link
Looks like we've slashdotted (or anandteched) that link. It's down because of data delivery restrictions.Anand should publish the instructions here.

Great to hear it worked. Can't wait for the review!
