嘿，老乡。 我在IBM的文档中发现如下内容，说（以后不支持了，而且是一个非user-level 命令，所以用处不大，可以不去研究了）：

Description
The bootinfo command is used during the boot and BOS install to gather and display information. During boot it is used to determine the boot device type and which device the machine has booted from. During a network boot, the bootinfo command displays the contents of the client's bootpd daemon REPLY packet. This information is used by the boot programs to contact the server to obtain the client's file systems.

The bootinfo command uses the device configuration databases in information searches. For some information, the bootinfo command uses NVRAM (nonvolatile random access memory).
