1. 恢复 Dell PowerEdge 服务器上的 BIOS 默认设置。
注意：重置 BIOS 会将所有设置清除回默认值。这可能会阻止您的系统引导至操作系统，直到重新应用自定义设置。
按照以下步骤还原系统设置页面中的 BIOS 默认设置。
-
开机。
-
当蓝色戴尔标识可见时，按 F2键进入系统设置程序。
- 进入 System BIOS 部分
- 单击低端角落的“默认”按钮。
- 出现确认信息时，按“Yes”（是）
- 已重置BIOS的设置。
如果它不起作用，请尝试按以下顺序操作：
- 按下Num Lock键，并验证Num Lock指示灯是否亮起。
- 按大写锁定键，并验证大写锁定指示灯是否亮起。
- 按 滚动锁定键，并验证滚动锁定指示灯是否亮起。键盘上的指示灯应全部亮起，如图1所示。
- 同时按 Alt+F键 。还原设置默认值时，系统会发出蜂鸣音。

2.使用主板跳线清除 BIOS
系统主板上位于钮扣电池旁边的跳线是NVRAM_CLR 跳线和 PWRD_EN 跳线。
这些可用于重置 BIOS。
主板示例 
| 跳线 | 设置 | 描述 |
|---|---|---|
| NVRAM_CLR |  （默认） |
配置设置在系统引导时保留（插针 3-5） |
 |
配置设置在下次系统引导时清除（插针 1-3） | |
| PWRD_EN |  （默认） |
密码功能已启用（插针 2-4） |
 |
密码功能已禁用（插针 4-6） |
步骤：
- 在服务器内部操作时，请确保使用静电放电 （ESD） 腕带
- 关闭系统，包括所有连接的外围设备，并断开系统与电源插座的连接
- 打开系统
- 从NVRAM_CLR跳线上拔下跳线塞 [请参阅上图以找到系统主板上的密码跳线（标记为 NVRAM_CLR）]
- 将跳线从插针 3-5 移至插针 1-3。
- 关闭系统，重新连接电源线
- 打开系统 10 秒
- 关闭系统
- 打开系统
- 将跳线移回插针 3-5 （默认）
- 关闭系统
- 将系统和外围设备重新连接至电源插座，并开启系统
您必须进入系统 BIOS，然后重新输入时间和日期以及所需的所有设置。
