  • Page 36: Overview Of Bios Features

    Overview of BIOS Features Introduction The motherboard uses an Intel/Phoenix BIOS, which is stored in flash memory and can be upgraded using a disk-based program. In addition to the BIOS, the flash memory contains the Setup program, Power-On Self Test (POST), the PCI auto- configuration utility, and is Windows 95-ready Plug and Play.
  • Page 37 Plug and Play: PCI Auto-configuration The BIOS automatically configures PCI devices and Plug and Play devices. PCI devices may be onboard or add-in cards. Plug and Play devices are ISA add-in cards built to meet the Plug and Play specification. Auto-configuration lets a user insert or remove PCI or Plug and Play cards without having to configure the system.
  • Page 38 ISA Plug and Play If Plug and Play operating system is selected in Setup, the BIOS auto-configures only ISA Plug and Play cards that are required for booting (IPL devices). If Plug and Play operating system is not selected in Setup, the BIOS auto-configures all Plug and Play ISA cards.
