177Bug initializes the parameter tables for a default configuration of controllers and devices (refer to Appendix C). If the system needs to be configured differently than this default configuration (for example, to use a 70MB Winchester drive where the default is a 40MB Winchester drive), then these tables must be changed. There are three ways to change parameter table contents:
❏ Using BO or BH. When you invoke one of these commands, the configuration area of the disk is read and the parameters corresponding to that device are rewritten according to the parameter information contained in the configuration area. This is a temporary change. If a cold-start reset occurs, then the default parameter information is written back into the tables.
❏ Using the IOT. You can use this command to reconfigure the parameter table manually for any controller and/or device that is different from the default. This is also a temporary change and is overwritten if a cold-start reset occurs.
Network I/O Support
The Network Boot Firmware provides the capability to boot the CPU through the ROM debugger using a network (local Ethernet interface) as the boot device. The booting process executes in two distinct phases:❏ The first phase: the diskless remote node discovers its network identify and the name of the file to be booted ❏ The second phase: the diskless remote node reads 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:
❏ Reception of packets
❏ Transmission of packets
❏ Receive buffer flushing
❏ Interface initialization This module ensures that the packaging and unpackaging of Ethernet packets is performed correctly in the Boot PROM.
