求教B2000不能进入系统问题。

As I posted earlier, your machine doesn't have NVRAM chip or it is broken. PROM gives you a program to run before the OS (like BIOS in PC world) and NVRAM chip stores machine configuration such as hostid, MAC address and a backup battery. Your host id and MAC are all 0s, which means PROM couldn't read NVRAM.

感谢指教，那就是说，没有ＮＶＲＡＭ就不能加载系统配置信息，当然也不能进入系统，即便重装系统也不能解决，如果我买一块装入主板前是否还得提前向ＮＶＲＡＭ中写入一些配置信息，如主机ＩＤ，网卡地址，否则还是出错。

上图，缺的就是它：

I don't think you can install OS without NVRAM clip since the PROM won't be able to find your boot disk. You don't need another motherboard. All you need is a NVRAM. If you do buy another motherboard with NVRAM on it, it comes with its hostid and MAC and you can't change it. (There is a way to hack the hostid at OS level though).

买个idrom把。

谢谢几位解答，准备买一只，但这玩意好像不好买，买来后还要修改HOSTID吧和网卡地址吧，但我也不知道原来的是多少。

    单买prom是比较贵一点，买到的都是SUN出厂时已经写好内容的prom，hostid、mac等都已经有了，每台B2000都通用的。不用你自己写入的。

刚才问了几个淘宝的卖家, 都不拆主板上的IDPROM卖, 不知道哪位知道这只IDPROM的型号,  我去电子市场上买一只相同型号的, 回来再写数HOSTID和网卡地址进去.
