SUMMARY = "Intel Processor Microcode Datafile for Linux"

HOMEPAGE = "http://www.intel.com/"
|

|
|
DESCRIPTION = "The microcode data file contains the latest microcode\
|
||
|
|
definitions for all Intel processors. Intel releases microcode updates\
|
||
|
|
to correct processor behavior as documented in the respective processor\
|
||
|
|
specification updates. While the regular approach to getting this microcode\
|
||
|
|
update is via a BIOS upgrade, Intel realizes that this can be an\
|
||
|
|
administrative hassle. The Linux operating system and VMware ESX\
|
||
|
|
products have a mechanism to update the microcode after booting.\
|
||
|
|
For example, this file will be used by the operating system mechanism\
|
||
|
|
if the file is placed in the /etc/firmware directory of the Linux system."
