Modified BIOS for Microserver N40L enables hidden features

Recommended Posts

I just want to share: The new BIOS version from 11/01/2013 by "Tobi" works without any problems. Windows Server 2012 R2 is now booting fine.


Is Tobi's mod in English? Thanks

He just changed some HEX values from the official HP-BIOS, which is available in some languages (don't know which yet) - but English is definelity one of them. So, yes, it's also in English.

Hi all,


well I had i´nstalled the BIOS MOD over 1 year ago somewhere end of 2012, and it worked fine - have 6 HDDs in my N40L running and did not do anything on the BIOS since then.

Now I see there were BIOS updates by HP in the meantime and do I understand it correct also a NEW MOD Version of these new HP BIOS ?


But as I remember correctly even if I find the NEW MoD BIOS (which version is the latest and where can I find it ?) , I also need the latest HP original BIOS ???? ( I dont remeber how the installation worked) ??

BUT, on the HP site I can no longer download updates without this service contract ??? where can I then get the original HO Bios I need to install the latest MOD Bios ??


Thanks for some help !

I'm sure that on the web are enough tutorials how to flash a new BIOS. Sadly I also can't remember how I did it on my old G7 - using now G8.

You can download the modded BIOS from Tobi here (2013.10.01 (A) (15 Nov 2013)):

When I read the instructions I found to flash the MOD BIOS - I understood that you need the original HP one to copy the .ROM file into this....but maybe I got it wrong.


By the way one other question as you just mentioned you now use the G8 - Is there also the possibility to enable or use 5 or 6 SATA ports like with teh N40L ?

(For SSD and 5 HDDs). Also which operating system you are using there ?

Can't imagine that you need the official BIOS for flashing a modded one... But maybe you need it.


That's a good question, but sadly I also can't tell you that. I'm using a hardware raid controller (HP Smart Array P420), which already offers me to use 8 drives at maximal speed, so I didn't ever care about. The HP MS G8 only has 7 SATA ports (the 7th is reserved for CD drive, but also can be used otherwise). I'm using VMware ESXi 5.5.

Ok thanks - then maybe someone else can confirm if I need the original HP BIOS or not (in the meantime I think just the original FLASH TOOL to be used and on The OnerDrive account there was one with teh "old" MOD BIOS - so maybe this can be used) ....



But also a general question - any way or source to get HP updates/Drivers for the N40L now w/o this service contract ?

I mean I am a private user - I cant/ Wont buy such a care pack , and also upgrading to Server 2012/Essentials etc... from my WHS2011... I mean I cant pay 400€ for the OS to MS as a provate user.... dont know if there is anywhere outside a cheaper offer but tahts what I get here asking - what I can use AFTER WHS2011....

Sorry, I don't know a other way to get the latest updates. I still have waranty for my G8, so I didn't care about yet. (I'm also using it just for private purposes). I also read sometimes that people are using normal client systems (e.g. Windows 8) as a server - maybe this would be a possibility for you (If there aren't no more left) or you choose using Windows Server 2012 R2. The cheapest method would be to start using Linux-based systems.

      Does anyone know if it is possible to get Agentless Management Service (AMS) running on Debian/Ubuntu Linux? It is always showing as Not Available in the iLO page and I have only ever seen this active in Windows.

      Hey guys,
      As of June 2020, what are the latest versions of firmware for HP Microserver Gen8 to be installed on the system itself? Also do any other components have updatable firmware/os-independent software?
      So far my list is as follows:
      BIOS - J06 (04/04/2019) iLO 4 - v2.73 (11/02/2020) Intelligent Provisioning - v1.71 (20/02/2019)  
      and I guess the following could also be added (although both out of date):
      Smart Update Manager (HP SUM) - v8.1.0 (21/12/2017) Service Pack for ProLiant (06/11/2017)  
      Date formated as DD/MM/YYYY.
      I believe all the B120i Smart Storage stuff is part of Intelligent Provisioning.

      New BIOS for Gen 8 Server now available that resolves Spectre vulnerability. My server is out of warranty. Anyone able to download and share?
      ** CRITICAL ** Online ROM Flash Component for Windows x64 - HP ProLiant MicroServer Gen8 (J06) Servers
      Version:2018.01.22 (5 Mar 2018)
      Fixes Upgrade Requirement:
      Critical - HPE requires users update to this version immediately.
      Important Notes:
      This revision of the System ROM includes the latest revision of the Intel microcode which, in combination with operating system updates, provides mitigation for Variant 2 of the Side Channel Analysis vulnerability, also known as Spectre. The revision of the microcode included in this System ROM does NOT have issues with more frequent reboots and unpredictable system behavior which impacted the previous Intel microcode which was part of the Spectre Variant 2 mitigation. Additional information is available from Intel’s Security Exploit Newsroom, https://newsroom.intel.com/press-kits/security-exploits-intel-products/.

      I have a simple question about my BIOS from iLo4. Look at the picture and you will see a difference in the System ROM and Backup ROM dates.

      Hey guys,
      Not sure if this is the correct section to post this, but in a bit of a pickle after attempting to flash my HP Microserver N40L to the modified bios last night.
      The story goes - I've had myN40L microserver for the past few years running Windows 8.1 and acting as a media server for the house. I recently upgraded a laptop I have so had a spare Samsung 840 EVO 120gb SSD that I thought I'd throw in the microserver as the boot drive. 
      I ghosted the existing windows install (which was on a 250gb mechanical hard drive) over to the SSD, rebooted the computer and everything was working file. When I checked the performance of the SSD using the Samsung Magician software it indicated thatt the SSD wasn't running at full speed due to AHCI being disabled. I then did a bit of research and found that SATA port 5 (normally meant for an optical drive) that the SSD was connected to doesn't run at full speed and in IDE mode. I read that the modified bios that's floating around for Microserver's can fix this.
      So I flashed the bios to my machine however now when I boot up it gets to the loading screen for windows and then errors and reboots. This boot loop just continues constantly with no way to get into windows.
      I've tried setting the hard drive mode to both IDE and AHCI in BIOS with no success, I've reverted the BIOS back to default settings, took out the CMOS battery overnight, tried to re-flash back to default HP firmware, re-flashed the modded BIOS with no drives in the server and even run the windows 8 startup repair with no success whatsoever, it just continues to error and boot loop.
      I did leave all 4 of my other SATA hard drives in the machine when flashing the modded bios originally so don't know if this affected it. I wish I'd just left the original BIOS on there now.
      Is there anything I can try to fix this? I'd really prefer not to have to reinstall windows 8 as it took me awhile to set everything up for media (Sonarr, CouchPotato, iTunes, Serviio etc).
      Any help is greatly appreciated.
      Cheers Benny
