Debian在线升级dell服务器BIOS
1. 安装libsmbios软件包:
aptitude update aptitude install libsmbios-bin
2. 查看当前BIOS版本及编号: 需要记住 System ID 及 BIOS Version 的值
hostname:/home/igi# getSystemId Libsmbios: 2.0.3 System ID: 0x01B3 Service Tag: XXXXXXX Express Service Code: XXXXXXXXX Product Name: PowerEdge 1950 BIOS Version: 2.2.6 Vendor: Dell Inc. Is Dell: 1
3. 下载对应BIOS的最新版本: http://linux.dell.com/repo/firmware/bios-hdrs/
- url格式: system_bios_ven_0x1028_dev_SYSTEM_ID_version_BIOS_VERSION
以 System ID为 0x01B3， BIOS Version为 2.2.6 为例
则需要找到: http://linux.dell.com/repo/firmware/bios-hdrs/ 下
对应的 system_bios_ven_0x1028_dev_0x01b3_version_x.x.x (x.x.x需要大于当前版本，如没有特别需求，使用最新版本即可)
对应的url为: http://linux.dell.com/repo/firmware/bios-hdrs/system_bios_ven_0x1028_dev_0x01b3_version_x.x.x/bios.hdr
wget http://linux.dell.com/repo/firmware/bios-hdrs/system_bios_ven_0x1028_dev_0x01b3_version_x.x.x/bios.hdr
4. 加载升级所需内核模块dell_rbu
modprobe dell_rbu
#确认模块已加载
lsmod | grep dell_rbu
dell_rbu 6800 0
firmware_class 7584 2 dell_rbu,bnx2
注意： 默认的debian内核已经有此模块，如果是其他内核，需要编译内核时做调整，推荐编译成模块

<M> BIOS update support for DELL systems via sysfs
5. 升级BIOS
dellBiosUpdate -u -f bios.hdr
输出示例
dellBiosUpdate -u -f bios.hdr WARNING: packet updates are not fully tested yet for packet modes v0/v2. We recommend that only monlithic updates be used at this point.
