Disk I/O Error Codes

162Bug returns an error code if an attempted disk operation is unsuccessful.

Network I/O Support

The Network Boot Firmware provides the capability to boot the CPU through the Flash/PROM debugger using a network (local Ethernet interface) as the boot device.

The booting process is executed in two distinct phases.

❏The first phase allows the diskless remote node to discover its network identify and the name of the file to be booted.

❏The second phase has the diskless remote node reading the boot file across the network into its memory.

The various modules (capabilities) and the dependencies of these modules that support the overall network boot function are described in the following paragraphs.

Intel 82596 LAN Coprocessor Ethernet Driver

This driver manages/surrounds the Intel 82596 LAN Coprocessor. Management is in the scope of the reception of packets, the transmission of packets, receive buffer flushing, and interface initialization.

This module ensures that the packaging and unpackaging of Ethernet packets is done correctly in the Boot PROM.

UDP/IP Protocol Modules

The Internet Protocol (IP) is designed for use in interconnected systems of packet-switched computer communication networks. The Internet protocol provides for transmitting of blocks of data called datagrams (hence User Datagram Protocol, or UDP) from sources to destinations, where sources and destinations are hosts identified by fixed length addresses.

The UDP/IP protocols are necessary for the TFTP and BOOTP protocols; TFTP and BOOTP require a UDP/IP connection.
