OK, sorry for the delay, I had some trouble with a Sil3512 card and my FreeNAS box. My MD5s and size info for SP3 and IE7 are as follows: WindowsXP-KB936929-SP3-x86-ENU.exe MD5=BB25707C919DD835A9D9706B5725AF58 size=331,805,736 bytes IE7-WindowsXP-x86-enu.exe MD5=EA16789F6FC1D2523F704E8F9AFBE906 size=15,452,536 bytes Does this look correct? Here is a screen capture of my XP Install copied file structure. I realized I had been using an install that included SP1 so I dug around and found an older disc that did not contain an SP at all. Unfortunately, after using this older XP install the integrating only SP3 and IE7 and testing the newly created install, I still get the same error of "acpi.sys not found" very early in the textmode setup. Logically the error occurs right as the setup begins to access acpi.sys or acpi related files. I can tell this because sometimes I can see the text flash in gray bar at the bottom of the screen for a moment before the message is displayed the install halts. I am baffled by this because I believe I must be the only person having this issue. Thanks again for you timely support! Ben
