comment How does systemd-tmpfiles work?
To test the link_power_management_policy for example: udevadm test /devices/pci0000:00/0000:00:1f.2/ata1/host0/scsi_host/host0/

comment How does systemd-tmpfiles work?
At wiki.archlinux.org/index.php/… there is a similar example ACTION=="add", SUBSYSTEM=="scsi_host", KERNEL=="host*", ATTR{link_power_management_policy}="min_power". Would you please explain why your UDEV rule here doesn't include an ACTION statement and isn't comma separated?

ASRock's claimed 1.5 seconds to logon to Windows 8 from a cold boot is actually 9.85 to 9.88 seconds on this system.

comment How much speed difference for a tweaked bios versus uefi boot?
@mikeserv I am already using efibootmgr and grub as a back-up route. I don't want an EFI shell because that doesn't run through SSH. And I don't need an EFI shell to write any efi var as Fedora 17 - 2 years ago already - was able to write to the efivars using a command like: cat file.bin > /sys/firmware/efi/vars/new_var according to ask.fedoraproject.org/en/question/8264/…

comment How much speed difference for a tweaked bios versus uefi boot?
@mikeserv In the current state of (kernel?) being unable to write/update the OsIndications EFI variable (unix.stackexchange.com/questions/152144/…), there is one useful case for the grub boot menu: to enter the UEFI firmware setup utility on next boot.

comment How much speed difference for a tweaked bios versus uefi boot?
@mikeserv The UEFI specification do specify the GPT partition table format, but not as must. Not all firmware handles MBR formatted drives well. That is why many of these tutorials - incorrectly - state that the partition must be GPT formatted. The Asrock AMI firmware does handle MBR formatted partitions well for UEFI boot. The MBR partition type id for EFI is ef. There is also a misunderstanding that existing BIOS boot installs can't be converted to EUFI boot: askubuntu.com/questions/509423/…

comment How much speed difference for a tweaked bios versus uefi boot?
@mikeserv The AsRock UEFI setup utility uses different terminology. Fast boot only disables some USB devices during devices. The GOP video card boot is named "Ultra Fast". I have updated the answer to better reflect this different. I don't understand the nature of your question regarding "boot the UEFI clean without an ESP". As far as I know an UEFI boot requires an ESP, and that is how I booted each "UEFI" and "UEFI stub" measurement. Could you please elaborate?

A better test would have been to change DHCP to static networking to not measure variations in time required for the DHCP address assignment. Changing DHCP to static makes the login prompt appear 2 seconds earlier.
