    BOOTP/RARP Request Control: Always/When-Needed (A/W)=W?
    BOOTP/RARP Reply Update Control: Yes/No (Y/N)       =Y?

(If you change the NIOT configuration, you will be asked whether you want to
make these changes permanent. Do not answer Y unless you plan to netboot
this board very often; be sure to have the ENV settings use a correct
address for the NIOT parameters block in this case. A valid setting is:

    Network Auto Boot Configuration Parameters Pointer (NVRAM) =
        00000000? FFFC0080

for example.

Once the NIOT parameters are set, it should be possible to boot the machine
from the server with the NBO command:)

----------------------------------------------------------
如果BOOTP/RARP Reply Update Control: Yes/No (Y/N)       =Y?後多了一行指令:
Network Auto Boot Configuration Parameters Pointer (NVRAM) =(Y/N)       ?=Y
(如果打入Y後出現無法存檔訊息,
方法一:不管他,直接nbo 00 00 ;如仍無法下載時;
方法二:先參考以下執行env去設定環境後,再niot....)
 
187-Bug> ENV
    Bug or System environment [B/S] = B?
    Field Service Menu Enable [Y/N] = N?

in order to boot directly into the BUG, without executing the complete
selftest sequence. Do not forget, after changing the ENV parameters, to
save the changes in NVRAM as suggested by the ENV command itself.

If the board has a built-in Ethernet controller, its address must be correct;
the LSAD command allows the address to be edited.

OpenBSD/mvme88k will not run correctly if the clock is stopped (power-saving
mode). Be sure to check that it is running by setting the current date with
the SET command.

If you plan to permanently boot from the network, make sure your ENV settings
match the following setup:

    Network Auto Boot Enable [Y/N]   = N? Y
    Network Auto Boot at power-up only [Y/N] = Y? N
    Network Auto Boot Abort Delay    = 5? 2 (or any value at your choice)
    Network Auto Boot Configuration Parameters Pointer (NVRAM) =
        00000000? FFFC0080

    187-Bug> NBO 00 00

**如果以上指令無法成功請參考再打以下：
187-Bug>NBO 00 00 163.32.123.199 163.32.123.200 tftpboot bsd.rd
(187-Bug>NBO 00 00 主機位址 tftp主機位址 tftpboot bsd.rd)


**安裝好開機
