Windows 7 on Virtual Box: Error 0xc0000225

I was trying to install Windows 7 Home Professional (64-bit) on a Virtual Box (4.1.2 r73507) VM. With the default VM setup, I kept getting an Error 0xc0000225 while the Windows 7 installer was starting. After reading some sites that stated that this was likely a BIOS issue, I edited the VM configuration to change the Chipset to "ICH9" and "Enable IO APIC". With this change the Windows installer was able to start without errors.
