Table 92.	DIM Code Checkpoints
	Checkpoint	Description
	2A	Initializes different buses and performs the following functions:
		• Function 0: Reset, Detect, and Disable - Disables all device nodes, PCI devices,
		and PnP ISA cards. Assigns PCI bus numbers.
		• Function 1: Static Device Initialization - initializes all static devices that include
		manual configured onboard peripherals, memory and I/O decode windows in PCI-
		PCI bridges, and noncompliant PCI devices. Reserves static resources.
		• Function 2: Boot Output Device Initialization - Searches for and initializes any
