MagicISO with Intel ICH10R RAID Array

Was having trouble getting MagicISO to install on my Windows 7 x64 Professional machine that I had just rebuilt. It worked fine before I installed new hard disks, but not now.

My new HDD have been installed in a RAID1 configuration using the built in Intel ICH10R RAID controller. This involved giving Windows a driver when installing (the built in one on the RTM CD does not load correctly and causes setup failures).

My CD drive is also on the same ICH10R bus, so a filter had been set on the drivers in the registry. This was stopping the successful installation of virtual CD drives which did not use the Intel bus.

The solution in this case is to remove the filters.

  1. Open regedit.
  2. Browse to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Class\{4D36E965-E325-11CE-BFC1-08002BE10318}
  3. Rename UpperFilters to UpperFilters.old
  4. Rename LowerFilters to LowerFilters.old
  5. Reboot your machine.

MagicISO should then install successfully and be able to create virtual drives.

The values that I had in my registry entries were: LowerFilters:iaStorF, UpperFilters: GEARAspiWDM. The first is created by the Intel RAID controller card, and the second is created when iTunes is installed.

After you have rebooted and installed MagicISO, you may need to rename UpperFilters1 back to the original name so that iTunes will load without an error.
