Physical Computer and Host Operating System Requirements

Following are the minimum system requirements for the physical computer and the host operating system:

• An x86-based or an x64-based computer with a 400 MHz or faster (1 GHz recommended) processor with L2 cache. Virtual PC supports the use of AMD Athlon/Duron, Intel Celeron, Intel Pentium II, Intel Pentium III, Intel Pentium 4, Intel Core Duo, and Intel Core2 Duo processors. You can run Virtual PC on a multi-processor computer, but it utilizes one processor only.

• CD-ROM or DVD drive

• Super VGA (800 x 600) or higher resolution monitor recommended

• Keyboard and Microsoft mouse or compatible pointing device

• Host operating system: Windows Vista Business, Windows Vista Enterprise, Windows Vista Ultimate, Windows Server 2003 Standard Edition, Windows Server 2003 Standard x64 Edition, Windows XP Professional, or Windows XP Tablet PC Edition

• For host disk space and memory, refer to the following table to determine the minimum required by the host operating system. This disk space is only a starting point in determining how much disk space you will need.

	Guest Operating System	Minimum Memory	Minimum Hard-Disk Space
	Windows 98, Windows 98 Second Edition	64 MB	500 MB
	Windows Millennium Edition (Windows Me)	96 MB	2 GB
	Windows 2000 Professional	96 MB	2 GB
	Windows XP Home Edition	128 MB	2 GB
	Windows XP Professional	128 MB	2 GB
	Windows Vista Enterprise	512 MB	15 GB
	Windows Vista Business	512 MB	15 GB
	Windows Vista Ultimate	512 MB	15 GB
	OS/2 Warp Version 4 Fix Pack 15, OS/2 Warp Convenience Pack 1, OS/2 Warp Convenience Pack 2	64 MB	500 MB

Examples

• Users will run Windows 98 and Windows 2000 as guest operating systems concurrently on Windows Vista Business. The minimum memory requirement is then 512 MB + 64 MB + 96 MB = 672 MB.

• Users will run Windows XP as a guest operating system on Windows Vista Ultimate. The minimum requirements is then 512 MB + 256 MB = 768 MB.
