I have read about the possibility of cloning windows XP to different machines instead of using unattended install, which takes a longer deployment time. According to what I know, becos of HAL and ACPI issues it was documented that cloning XP can only be applied to similar machines but not machines with different hardwares like motherboard chipsets n storage devices. U could get blue screen straight if u were to do that!!! But if u follow some procedures before u do the clone, u can create a "Ultimate Windows XP installation CD" clone that can install on most desktop machines with unidentical hardware....in abt 15 mins time!!! According to the writeup,u need the following: 1)Windows XP Corporate (volume licensing edition) - version that do not require activation 2) Partition into C: where u install windows XP to C:, & have a parition D: to store the created image clone The procedure is something like this: 1) Install a working copy of WinXP Corp VLE on your PC 2) Install all SP, applications and configure whatever software you want 3) Uninstall specific hardware that u have in your machine using device manger eg: Network card, sound, modem ,game controllers, display card... When u are prompted to restart, select "NO". This is important as windows XP will redetect these hw when the clone boots up in the new machine. 4) Change ACPI configuration driver to use "Standard PC" by clicking on "driver update" under "ACPI uniprocessor PC" under "Computer" in device manager. when prompted to restart, click "No". This is important, becos different machines have different ACPI architecture, if not done it can cause boot failure n blue screen. For most 2003 and above PCs u will see "ACPI uniprocessor PC" as the setting. 5) Finally change the IDE ATA/ATAPI controllers to use "Standard Dual Channel PCI IDE Controller" by performing the driver update selection. This is crucial as this is the common controller standard used in different motherboad chipsets.U will be prompted to reboot, choose "No". 6)To ensure more stability and uniqueness due to SID issues, we need to use the sysprep tool to prepare the computer b4 the cloning, Use the setup manager to create the sysprep.inf auto answer n place in the C:\sysprep folder. Finally reboot and power off the machine. 7) The disk is ready to be clone now. Boot up using the cloning software of your choice, eg: Ghost 2003 n clone the C: to D: as an image file This clone can be installed on most motherboard with INTEL, VIA or SIS chipsets, according to the write up, but may not be able to clone onto laptops due the hardware architecture. I have not tested out this method yet but it seems that the procedures actually works. Would appreciate any comments if anyone has tried doing something like that... Thanks
