- Your vendor releases a UEFI/BIOS update image for CD
- ...but your machine does not have a CD
- So basically what has to be done is to get this image to boot from another media, i.e. USB
- ...but the relevant update utilities and data on the CD are hidden by a special setup.
- The sysutils/geteltorito solves this issue.
If you don't want to browse the contents of the image, ovbiously you can omit the mdconfig(8) and use the image file in the
dd if=fileinstead of /dev/md0
You may want to add
status=progressto the dd(1) command, or use sysutils/pv (install it 1st) like this:
pv -tepb /dev/md0|dd of=/dev/da0 bs=64k conv=sync
$ su -
# pkg install geteltorito && exit
$ cd ~/Downloads
$ geteltorito -o jbuj73wd.img jbuj73wd.iso
$ su -
# mdconfig jbuj73wd.img
# dd if=/dev/md0 of=/dev/da0 bs=64k conv=sync
# mdconfig -du 0
The prepared USB media should boot and install the UEFI/BIOS update.
If you encounter a message like "Press CTRL+P to enter the management console" and you don't have a password for that, well that's another story. Welcome in the brave new world . If an empty password works, this means
- you're in urgent need for an update
- You should immediately set it to a reasonable value according to your security demands
