    摘要： A technique for accessing features of a hardware adapter includes reading a first key from a hardware adapter and attempting to decrypt the first key with a second key. In response to the second key successfully decrypting the first key: encrypted code from the hardware adapter is read; the encrypted code is decrypted with the decrypted first key to generate unencrypted code; and a default code in an executable flash sector of the hardware adapter is over-written with the unencrypted code. In this case, the unencrypted code facilitates access to at least one feature of the hardware adapter that is customer specific. In response to the second key not successfully decrypting the first key, the default code in the executable flash sector of the hardware adapter is not over-written. In this case, the default code facilitates access to one or more features that are not customer specific.

    摘要翻译： 用于访问硬件适配器的特征的技术包括从硬件适配器读取第一密钥并尝试用第二密钥解密第一密钥。 响应第二个密钥成功解密第一个密钥：读取硬件适配器的加密代码; 加密代码用解密的第一密钥解密，生成未加密的代码; 并且硬件适配器的可执行闪存扇区中的默认代码被未加密的代码重写。 在这种情况下，未加密的代码便于访问客户特定的硬件适配器的至少一个特征。 响应于第二个密钥未成功解密第一个密钥，硬件适配器的可执行闪存扇区中的默认代码不会被覆盖。 在这种情况下，默认代码便于访问一个或多个不是客户特定的功能。
