19.7 Legacy Series / Microcode update
« on: September 17, 2019, 09:23:50 pm »
Trying to mitigate meltdown and spectre: followed this guide for update the microcode:
* CPU microcode is the latest known available version: NO (latest version is 0x7030106 dated 2018/02/09 according to builtin MCExtractor DB v112 - 2019/05/22)
# pkg install devcpu-data
# vi /boot/loader.conf
# cat /boot/loader.conf
cpu_microcode_load="YES"
cpu_microcode_name="/boot/firmware/intel-ucode.bin"
# reboot
but when I reboot the loader.conf is resetted by default, and microcode was not updated. Is there a way for disable the rewrite protection and then enable after update it?
