83 Altos G710DIM Code CheckpointsThe Device Initialization Manager (DIM) module gets control at various times during BIOSPOST to initialize different BUSes. The following table describes the main checkpoints wherethe DIM module is accessed:Checkpoint Description2AInitialize different buses and perform the following functions:T Reset, Detect, and Disable (function 0). Function 0disables all device nodes, PCI devices,and PnP ISAcards. It also assigns PCI bus numbers.T Static Device Initialization (function 1). Function 1initializes all static devices that include manualconfigured onboard peripherals, memory and I/Odecode windows in PCI-PCI bridges, and noncompliantPCI devices. Static resources are also reserved.T Boot Output Device Initialization (function 2). Function2 searches for and initializes any PnP, PCI, or AGPvideo devices.38Initialize different buses and perform the following functions:T Boot Input Device Initialization (function 3). Function 3searches for and configures PCI input devices anddetects if system has standard keyboard controller.T IPL Device Initialization (function 4). Function 4searches for and configures all PnP and PCI bootdevices.T General Device Initialization (function 5). Function 5configures all onboard peripherals that are set to anautomatic configuration and configures all remainingPnP and PCI devices.
