80386SX CPU

Your system uses an Intel 80386SX-20 microprocessor running at
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
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 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.
