. The SL was designed for use in mobile computers. It was produced between November 1992 and June 1993. Clock speeds available were 20, 25 and 33 MHz. The i486SL contained all features of the i486DX. In addition, the

System Management Mode System Management Mode (SMM, sometimes called ring −2 in reference to protection rings) is an operating mode of x86 central processor units (CPUs) in which all normal execution, including the operating system, is suspended. An alternate ...

(SMM) (the same mode introduced with i386SL) was included with this processor. The system management mode makes it possible to shut down the processor without losing data. To achieve this, the processor state is saved in an area of static RAM (SMRAM). In mid-1993, Intel incorporated the SMM feature in all its new 80486 processors and discontinued the SL series.
