总结了187Bug调试器命令。这个命令语法使用中前面解释的符号显示本章。CNFG和ENV命令在中进行了解释附录A.控制器、设备及其LUN列在附录B或附录C。所有其他命令详细信息包括MVME187Bug调试包用户手册中对此进行了解释。本附录涵盖
❏ 配置电路板信息块❏ 将环境设置为错误/操作系统
❏ 环境命令参数配置电路板信息块CNFG[；[I][M]]
此命令用于显示和配置电路板信息块。该区块位于非易失性
IS230TCISH6C燃机模块RAM（NVRAM）。参考MVME187 RISC单板实际位置的计算机用户手册。
信息块包含各种元素，详细说明了特定的硬件的操作参数。MVME187 RISC单曲
Board Computer用户手册介绍了电路板信息块，并列出每个电路板的大小和逻辑偏移量
要素CNFG命令不描述元素和它们的使用。对电路板信息块内容进行校验和用于验证目的。该校验和是块请注意，引用的参数是左对齐字符（ASCII）字符串填充空格字符，引号（“）为显示以指示字符串的大小。不适用的参数引用的被视为数据字符串，数据字符串是右对齐的。如果长度不为0，则用零填充数据字符串遇见。
如果董事会信息块损坏，则命令显示问号“”对于不可显示字符。警告消息（警告：电路板信息块校验和错误）也会在校验和失败的情况下显示。使用I选项初始化电路板的未使用区域信息块归零。允许使用命令的M选项进行修改。在修改会话结束时，系统会提示您输入更新至非易失性RAM（NVRAM）。Y响应必须为进行更新；任何其他响应终止更新（忽略所有更改）。更新还重新计算校验和。修改参数时要小心。这些参数是由工厂初始化，正确的电路板操作取决于这些参数。
The 187Bug debugger commands are summarized in Table 5-1. The
command syntax is shown using the symbols explained earlier in
this chapter. The CNFG and ENV commands are explained in
Appendix A. Controllers, devices, and their LUNs are listed in
Appendix B or Appendix C. All other command details are
explained in the MVME187Bug Debugging Package User's Manual.This Appendix Covers
❏ Configuring the board information block
❏ Setting the environment to Bug/Operating System
❏ Environment command parameters
Configuring the Board Information Block
CNFG [;[I][M]]
This command is used to display and configure the board
information block. This block is resident within the Non-Volatile
RAM (NVRAM). Refer to the MVME187 RISC Single Board
Computer User's Manual for the actual location.
The information block contains various elements detailing specific
operation parameters of the hardware. The MVME187 RISC Single
Board Computer User's Manual describes the elements within the
board information block, and lists the size and logical offset of each
element. The CNFG command does not describe the elements and
their use. The board information block contents are checksummed
for validation purposes. This checksum is the last element of the
block. Note that the parameters that are quoted are left-justified character
(ASCII) strings padded with space characters, and the quotes (") are
displayed to indicate the size of the string. Parameters that are not
quoted are considered data strings, and data strings are rightjustified. The data strings are padded with zeroes if the length is not
met.
In the event of corruption of the board information block, the
command displays a question mark "?" for nondisplayable
characters. A warning message (WARNING: Board Information Block
Checksum Error) is also displayed in the event of a checksum failure.
Using the I option initializes the unused area of the board
information block to zero.
Modification is permitted by using the M option of the command.
At the end of the modification session, you are prompted for the
update to Non-Volatile RAM (NVRAM). A Y response must be
made for the update to occur; any other response terminates the
update (disregards all changes). The update also recalculates the
checksum.
Be cautious when modifying parameters. These parameters are
initialized by the factory, and correct board operation relies upon
these parameters.
