Host operating systems

Virtual PC 2007 officially supports the following host operating systems:

Windows Vista (32-bit and 64-bit versions of Windows Vista Ultimate, Enterprise, Business editions and European Business N only) not Windows Vista Starter, or European Vista Home N editions).
Windows XP Professional and Tablet PC Edition (32-bit) and Windows XP Professional x64 Edition.
Windows Server 2003
NOTE: Some operating systems that are not officially supported, including Windows Vista Home Premium, Windows XP Media Center Edition, or XP Home Edition

Virtual PC emulates the following.

32-bit Intel Pentium II processor (but virtualizes the host processor on Windows versions) with an Intel 440BX chipset
standard SVGA VESA graphics card (S3 Trio 32 PCI with 4 MB Video RAM, adjustable in later versions up to 16 MB)
system BIOS from American Megatrends (AMI)
Creative Labs Sound Blaster 16 ISA PnP (when Vista is installed as both the host (main) and guest (virtual) Operating systems, then the need to set audio configuration is removed, as the guest (Virtual) OS automatically synchronizes the settings with the host (main) Operating System.)
DEC 21041 (DEC 21140 in newer versions) Ethernet network card.
