MBA supports the Preboot eXecution Environment (PXE 2.x), as specified in the Wired for
Management (WfM V2.0) and Microsoft PC 98 and PC 99 guidelines. PXE software allows PCs
to communicate with server-based workstation management applications, which adhere to
WfM specifications, to perform such tasks as:

Software installation

Configuration

Administration

Problem diagnostics and resolution

The PCs can be normal legacy PCs (upgraded with MBA ROMs), new Managed PCs, or Net
PCs.
