T400 and Incompatibility with Advanced Configuration and Power Interface (ACPI) PC Hal.dll

Question

I manage the master XP image for our company and I have managed to keep 1 master image for every model of laptop hardware we have, from older P3's all the way to the T61's using the Advanced Configuration and Power Interface (ACPI) PC Hal.dll.  During the sysprep process, the user would have the option to update the HAL to the ACPI Multiprocessor PC.  Unfortunately, the new T400 and (W500's also) seem to be incompatibile with this HAL.  On the sysprepped image, I get a black screen on initial boot-up.  On reboot, I am asked if I want to start in safe mode.  I also played around with the Standard PC HAL and it also exhibited the same problems.  The only HALs that will work are the ACPI Uniprocessor PC HAL and ACPI Multiprocessor PC.  Using either one of these HALs on my master image could be incompatibile with older hardware.  I hate to have to move to maintaining two images.  Anybody have any experience in getting the Advanced Configuration and Power Interface (ACPI) PC HAL working on these new Lenovo models?  Thanks in advance.

Answer 1

I also have the same problem.
I have a hardware independant image that i have built in MS VPC / MS VS05 which is then sysprep'd and captured into a WIM file.
Before i built my base image in the virtual environment, i configured all the automation files used to install windows, to include the latest Intel Matrix drivers v8.5, including the sysprep files in the base image.
I have a custom WinPE v2.1 that the machine boots of the network, and runs a vbscript in the background to partition the disks, and map drives to the network, it then extracts the WIM file to the hard disk, and copies the required drivers from the network share for the model being imaged, and then proceeds to updating the sysprep.inf.
One of the process's that is performed is checking what HAL to write into the sysprep file.
I have forced all the different types of HAL's by hard coding them in the sysprep, but after the machine reboots i get the black screen of nothing and no hard disk activity, if i reboot into safe mode it freezes on agpCPQ.sys.
I use this build process to support around 5,000 different machines at two different companies, there is proberly about 30 different models of machines that are supported by this image, (HP, Acer, Toshiba, IBM, Lenovo)and i only have the issue with the new Lenovo x301, T400 & T500.
I have spoken with Lenovo Australia, and dealt directly with the advanced system engineers and even forwarded them a copy of my image for testing, so far they have not been able to provide a solution.
They also sent me a copy of the restore disks for those models and windows xp installed without an issue, but the difference is that their image does a fully automated install where as my image is a sysprep'd image.
I checked the machines HAL type after it was imaged, and it is the same as the HAL used inside my VM Image.
