80386SX CPU Your system uses an Intel 80386SX-20 microprocessor running at 20MHz. The 80386SX has a number of features that enable a substantial leap in processing power and capability over the 80286 standard used in AT-type microcomputers. The 80386SX has superior extended memory support and will execute the new 32-bit programs of the future. The 80386SX-20 CPU is vastly superior in capabilities and speed to the 80286, and can handle: • Concurrent processing • Hardware-based multitasking • Superior extended-memory support; and • Virtual machines Virtual machines can create discrete, non-interfering operating environments for application programs, giving each application its own working environment. Virtual machines can be created within the extended memory by using appropriate control software. Your system is switchable between 10 and 20MHz to ensure software compatibility and can be activated with either a hardware or software switch. For software that fails to operate at Turbo mode you may switch to the Normal speed. Chapter 2: Setting Up Your System 3

20MHz. The 80386SX has a number of features that enable a substan-
tial leap in processing power and capability over the 80286 standard
used in AT-type microcomputers. The 80386SX has superior extended

•
Superior extended-memory support; and
•

Virtual machines can create discrete, non-interfering operating en-
vironments for application programs, giving each application its own
working environment. Virtual machines can be created within the ex-
tended memory by using appropriate control software.
Your system is switchable between 10 and 20MHz to ensure software
compatibility and can be activated with either a hardware or software
switch. For software that fails to operate at Turbo mode you may
switch to the Normal speed.
