如果你在研究 fedora 16 裡的 microcode_ctl 的使用方法~

你可以簡單這麼作

1. 去 intel or amd ...下載 Linux* 處理器微碼資料檔案

http://downloadcenter.intel.com/Detail_Desc.aspx?agr=Y&DwnldID=20728&lang=zht&OSVersion=Linux*&DownloadType=%E9%9F%8C%E9%AB%94

解壓後，應該只有一個 microcode.dat

請放到 /lib/firmware/microcode.dat

2. yum install microcode_ctl

3.

[root@3wa ~]# /sbin/microcode_ctl -u
/sbin/microcode_ctl: writing microcode (length: 460800)
/sbin/microcode_ctl: microcode successfuly written to /dev/cpu/microcode
[root@3wa ~]#

4.

[root@3wa ~]# modprobe microcode

5.

reboot

應該就會看到…

[root@3wa ~]# dmesg |grep microcode

[root@3wa ~]#

6.

[root@3wa ~]# lsmod|grep microcode
microcode              18550  0
[root@3wa ~]#

類似這些了，這樣就確實把 microcode 弄上去了

高興就好 ^_^
