使用 SUM 工具修改超微 BIOS 配置

2019-05-08 分类：System 标签：Bios

WHY

厂里有一批 过保 的 Supermicro 3U8 机器 CPU 没有启用 超线程

虽然超微 3U8 机型 X9SRD-F 主板使用的也是 AMI BIOSBIOS Type: 32Mb SPI Flash EEPROM with AMI BIOS

但之前针对 H3C 机型修改 BIOS 的 SCELNX 工具不能用：

# SCELNX_64 /o /lang /s BIOS-with-map-string.cfg /hb

Platform identification failed.

AMI 官网也没找到适配该主板的工具下载，只得用超微自己的 SUM 工具来修改

License Key

使用 sum 工具修改 BIOS 需要 License Key 厂里的机器也都没有 –.

好在超微 旧机型 (2012-2018) 的 License 算法已经被 逆向 出来了：

根据 OOB Mac 地址计算 License Key ：

oob_mac_str=$(ipmitool lan print|awk '/^MAC Add/{print $4}')

oob_hex_key=8544E3B47ECA58F9583043F8

echo "$oob_mac_str"|xxd -r -p|openssl dgst -sha1 -mac HMAC -macopt "hexkey:${oob_hex_key}"|awk '{print $2}'|awk -v FIELDWIDTHS='4 4 4 4 4 4' -v OFS='-' '{$1=$1;print }'

a2a5-e0de-ebbe-0862-53e2-5e16

导入 License Key ：

# ./sum -c ActivateProductKey --key a2a5-e0de-ebbe-0862-53e2-5e16

然后就可以使用 sum 工具配置 BIOS 了，先查看当前 BIOS 里的 超线程 HT 配置项：

# ./sum -c GetCurrentBiosCfg |grep -C3 -i thread

[Advanced|CPU Configuration]

Clock Spread Spectrum=00 // *00 (Disabled), 01 (Enabled)

RTID=00 // *00 (Optimal), 01 (Alternate)

Hyper-threading=00 // 00 (Disabled), *01 (Enabled)

Limit CPUID Maximum=00 // *00 (Disabled), 01 (Enabled)

Execute Disable Bit=01 // 00 (Disabled), *01 (Enabled)

Intel(R) AES-NI=01 // 00 (Disabled), *01 (Enabled)

当前没有启用，生成启用 HT 的 BIOS 配置文件：

# echo '[Advanced|CPU Configuration]

Hyper-threading=01 // 00 (Disabled), *01 (Enabled)' > ht.cfg

# cat ht.cfg

[Advanced|CPU Configuration]

Hyper-threading=01 // 00 (Disabled), *01 (Enabled)

最后 sum 通过生成的 启用 HT 配置文件 修改 BIOS ：

# ./sum -c ChangeBiosCfg --file ht.cfg

Status: Start updating the BIOS configuration for the managed system

************************************WARNING*************************************

Do not remove AC power from the server.

********************************************************************************

Status: The BIOS configuration is updated for the managed system

Note: You have to reboot or power up the system for the changes to take effect

修改成功后，还需 重启 服务器才能生效。重启之后，确认 HT 是否生效：
