VPC hardware comparison
|Category||Virtual PC (2004, 2007)||Notes|
|Floppy disk drive||Supported||Both versions support 720 KB and 1.44 MB disk images.|
|Power management||APM 1.2, ACPI||Only the basic ACPI tables are supported, with no MADT or derived tables. I'm trying APM in a few weeks.|
|CD/DVD||CD supported||Can use either an ISO image, or the host computer's physical CD or DVD drive.|
|Sound||Supported||The sound card emulated is the Creative Labs Sound Blaster 16 (ISA), which supports digital signal processing and FM synthesis.|
|Ports||LPT1, COM1 and COM2||LPT1 is redirected to a physical parallel port. The serial ports are redirected to either a file, named pipe or physical port.|
|Video||S3 Trio PCI|| VESA 2.0 is supported.
The maximum supported resolution is 1600x1200. 8 MB of video RAM is available, but to access it, VPC additions are needed. S3 Trio graphics acceleration is fully supported.
|Keyboard||Supported||Controller chip is Intel 8255.|
|Motherboard||Emulates Intel 440BX||Contains the PIC (8259), PIT (8254), DMA controller (8237), CMOS and RTC.|
|Mouse||Supported||PS2 mouse supported on IRQ 12.|
|Network||Intel/DEC 21140|| This is an Ethernet card. It supports the five most common packet types:
Both unicast and multicast packets are supported.
|Processor||Intel Pentium 3||The host computer's processor is virtualised.|
|APICs||Not supported||Virtual PC doesn't support any APICs of any type. You're stuck with the PIT|
