Software
The Little Board/486e CPU can use most commercial and public-domain software developed for the
IBM PC and PC/AT. Software development tools such as editors, compilers, and debuggers can be
used to develop application code. System requiremen ts can be quickly ta ilored to yo ur nee ds u sing
these standard tools with the utilities and drivers supplied with each Little Board/486e CPU.
The board’s SETUP function can be used for all system configuration tasks. SETUP can be invoked
using the (CTRL-ALT-ESC) hot-key combinatio n or by se lectin g th e SE TUP.CO M u tility pro gr am
from the DOS command line. SETUP.COM is available on the Common Utilities diskette. Table 1–1
