1 | SUMMARY = "Intel Processor Microcode Datafile for Linux" | ||
2 | HOMEPAGE = "http://www.intel.com/" | ||
3 | DESCRIPTION = "The microcode data file contains the latest microcode\ | ||
4 | definitions for all Intel processors. Intel releases microcode updates\ | ||
5 | to correct processor behavior as documented in the respective processor\ | ||
6 | specification updates. While the regular approach to getting this microcode\ | ||
7 | update is via a BIOS upgrade, Intel realizes that this can be an\ | ||
8 | administrative hassle. The Linux operating system and VMware ESX\ | ||
9 | products have a mechanism to update the microcode after booting.\ | ||
10 | For example, this file will be used by the operating system mechanism\ | ||
11 | if the file is placed in the /etc/firmware directory of the Linux system." | ||
