Phar Lap (company)
From Wikipedia, the free encyclopedia
Phar Lap was software company specializing in software development tools for the MS-DOS/PC-DOS operating systems. They were most noted for their software allowing developers to access memory beyond the 640 KiB limit of DOS (DOS extenders) and were an author of the VCPI standard.
Phar Lap Software, Inc. was founded in April 1986 by Richard M. Smith, Robert Moore, and John M. Benfatto. Their first major success, 386|DOS-Extender, a 32-bit protected mode development tool, was released in November 1986.
Phar Lap’s product line was expanded to include 386|VMM, a virtual memory add-in driver, LinkLoc, a linker-locator for embedded development; cross tools for embedded development; and 286|DOS-Extender, a 16-bit protected-mode development tool.
Phar Lap developed the Virtual Control Program Interface (VCPI) in cooperation with Quarterdeck Office Systems, who produced the DesqView task-switching software. Phar Lap was also a member of the 12-firm committee that designed the DOS Protected Mode Interface (DPMI). VCPI and DPMI are industry standards allowing DOS extenders to co-exist with EMS emulators and multi-tasking environments.
Phar Lap received several major PC industry awards for VCPI, 386|DOS-Extender, and 286|DOS-Extender.
Phar Lap was named for the great New Zealand race horse Phar Lap. The horse was rather inelegant in appearance, but performed spectacularly, setting everyone on their heels until he died a mysterious death. Software allowing application programs to reach beyond the 640 KiB limit was a brilliant hack: it was not elegant in appearance, but it performed spectacularly, setting everyone on their heels when it worked correctly, and causing programs to die mysterious deaths when utilized by a careless programmer.
There was no mystery when the market for DOS extenders died, however; they were not needed by 32-bit Windows applications which could directly address all the memory the computer hardware would support.
