Microsoft confirmed on Wednesday that the recently released Virtual PC 6.1 is not compatible with the new Power Mac G5. “Currently, Virtual PC 6.1 does not run on the Power Mac G5,” Microsoft’s Sandra Peignaux told Macworld UK. Users attempting to install the Windows emulation software will get an error message, saying: “This application is not supported by the CPU.” Peignaux said “Virtual PC relies on a feature of the G3/G4 processors called ‘pseudo little-endian mode’ for increased performance when emulating a Pentium processor.” Because the G5 processor does not support this feature, “much of the program will have to be rewritten to work on G5’s.” Support for the new Power Macs will be introduced in a future release, she confirmed. No timeframe was given for the update.
