BIOS maker Phoenix Technologies' plans to market a new application platform the company claims will solve a number of problems endemic to Microsoft's Windows platform might be taken as a provocative gesture at their longtime partner. But Redmond's immediate reaction was nonchalant. On Monday, the Milpitas, Calif., software maker announced Hyperspace, a Linux-based virtualization platform that will let OEMs bundle cut-down versions of popular open-source software that end-users will be able to access instantly, even without booting Windows. "We call this embedded simplicity, or PC 3.0," said Woody Hobbs, CEO of Phoenix in an interview.Phoenix has for many years been the leading maker of BIOS, which enables a PC's Windows operating system to communicate with the hardware. But BIOS is being slowly supplanted by a newer technology called Unified Extensible Firmware Interface (UEFI).
