Motherboard Configuration
A typical motherboard has several options and proper configuration is re- quired to select the required hardware setup.
• Most of the PC and XT class motherboards are set/configured using jumpers or switches on the motherboard.
• In the AT and later machines, the configuration options are stored in CMOS RAM and are set using the SETUP utility in the BIOS ROM. The motherboard configuration should always be perfect, as an incorrectly setup motherboard can cause the system to malfunction or even crash.
