N54L Bios /WOL /HDD SpinDown


Recommended Posts

Hello, first of all I apologize for my English.

I hope this post can help more people having the same problems.

Took 2 days reading post in the forum and testing in my n54l with XPEnology DS3612xs DSM 4.3 build 3810++ (repack v1.0) (Great Work)


problems encountered


bios corruption

After much testing I have come to the conclusion that corruption changes occurring in different outfits, occurs when programming an automatic start. Automatic or manual shutdown does not reproduce the problem in my n54l.

Corruption includes damage to the system time, reset the bios settings and even corruption that prevents booting (need reinstall original bios)


Wake on lan

It works by changing the mac and running the command

ethtool -s eth0 wol g




HDD Spin Down / Hibernation

THANKS for the script

sync; /usr/syno/bin/synousbdisk -umount sdu; >/tmp/usbtab

It is necessary to remove the USB pendrive for the disks enter in a state of hibernation (bug?)

The BIOS corruption is caused by DSM's tight coupling with the hardware and its base software (the BIOS). On all Synology products, there's a custom BIOS with specific fields that control e.g. automatic boot, etc. Now, the problem begins with the way a general BIOS is built - it is a very basic set of code, and provides no higher level accessibility (you cannot modify BIOS from a running OS using a general interface, unlike UEFI) With BIOS, you need to write direct bytecode on the CMOS chip. And as Synology's BIOS structure is different from the regular BIOS', direct writing of the CMOS corrupts it. In some cases it even makes the system unbootable.


For me the biggest problem was the "pinkeye" bug, that caused the HP health LED stay blue no matter what. The BLUE LED was simply always active. Even if another LED was active, in my case, this was the red LED, making it a really vivid pink.

Trying to get the HDD hibernation working.

Running 4 3TB WD green in the bays and an 750GB sata on the top shelf.


They dont seem to hibernate even though ive followed your fine links in the earlier post.


Is it possible you could tell me what bios youre using and your settings regarding the sata ports ?

Use synousbdisk -enum to locate the mount name in my case is sdu use the script


sync; /usr/syno/bin/synousbdisk -umount sdu; >/tmp/usbtab


enter in hdd configuration and set 10 minutes hdd hibernation, and check log entry.


Disconnect from web interface and wait 10 minutes...


Its working on default BIOS settings on 4.3. I only changed SATA speed to 3.0 Gbps and video memory to minimun.


other BIOS settings I've tested and works:

To enable top SATA port and HOT Plug.

From the main screen go to ‘Chipset > Southbridge Configuration > SB SATA Configuration’ and make sure your settings are the same as below


OnChip SATA Channel = Enabled

OnChip IDE Type = IDE

SATA IDE Combined Mode = Disabled

SATA EPS on all PORT = Enabled

SATA Power on all PORT = Enabled


follow this link http://www.synology.com/en-us/support/faq/568 for other limitations


Good luck.
