Included in this archive are the drivers for the two unknown devices prevelant on HPML1xx series servers.

The IPI0001 Driver is in x32 and x64 versions (I realise the names look wrong, they aren't)
The HPI0002 Driver must be installed manually, just go into device manager, right click the unknown device and "Install Driver", then point it at this folder.

Good work HP...



HP ML Series Server - Unknown Devices
While installing a new server here, I came upon one of the more annoying problems in installs, missing drivers.  This is a brand new HP ML150 with Windows 2003 Standard x32, I installed all the drivers that came on the support CD, and did all my windows updates.

Still, the problem remained of two unknown devices with ID ACPI\HPI0002\0 and ACPI\IPI0001\0

After much looking around, I ended up tracking the two items down - they are not located on the CDs, and one of them is not even available for download without calling HP!  The files are now located here -> http://www.block.net.au/help/files/HPDrivers.zip

That zip file contains the drivers necessary for most HP Servers with this problem, including the ML150 and ML110 - the readme.txt file is effectively just the instructions of which is which.

One driver has an executable that will install it for you, the other must be done the old fashioned way.

Good luck!
