Blue screen in vm with iastor.sys 9.6.0

Recommended Posts

I had integrated the Intel storage drivers with the version 8.9.0 a while ago. Using Fernando's enhanced driver pack for my ICH10 chip, this worked perfectly.

When switching to the 9.6.0 version, I started getting blue screens in my virtual test machine (STOP 0x7E). This happens during textmode setup right after the drivers are have been loaded, when the actual setup is started (EULA page, etc.).

After some frustrating trials, I found iastor.sys to be the problem. Using the 8.9.0 sys file, setup continues.

To avoid having to use different versions of my DVD for testing and real installations, I would appreciate it if I could indeed use the latest drivers also with my VM. I have attached my txtsetup.sif snippet for the drivers that I made based on Fernando's txtsetup.oem.

What I find strange is that the sys file should actually be loaded at all in a VM since the corresponding hardware is not there; but why else would I get a blue screen with one sys file and not the other?

I'm having the same issue. I think that all of the drivers you list to load either through txtsetup.sif or textsetup.oem method get loaded into memory during the phase of setup enumerating the plug and play drivers.

I'm using a single image delivered with Windows Deployment Services that supports lots of different models of Lenovo and older IBM desktops and laptops. I need the new Iastor.sys for some of the newer models, and it works just fine for them, but it's giving some of the older machines a BSOD. Just like your issue the machine getting the BSOD doesn't even need the iastor.sys driver to begin with.

This is indeed true, which is why you're seeing it even on a VM, OP. It's probably best to determine hardware (in a WinPE environment) before attempting to restore an image, and then inject the proper drivers for the hardware at that time. You could consider using MDT 2010 for this, but you would have to use flat-file or sysprep installs (not WIM image captures) to install XP from MDT-created media.
