Modified BIOS for Microserver N40L enables hidden features

Recommended Posts

Perfect, thank you for the screen shots.


I have two RAID 1 disks configured on my microserver will updating the BIOS cause any problems with the RAID configuration?


Also another question about the RAID configuration on the microserver, is the onboard RAID controller a software based controller or hardware based, and if it's software based is it any better than the mirror ing that I could set up in Windows disk manager?

Not saying that it will, but I would check the consistency of the array after you mod the BIOS. If this were an approved procedure from HP, I would have no worries, but since this is a hack, I'd check the array afterwards.

If it's like every other mobo-based RAID I've seen, it's a hybrid between hardware and software. One disadvantage of it is it's very unlikely it could be moved to another box if the mobo fails; with add-in RAID cards this is usually possible. It's also often possible with Disk Manager based RAID. You can normally just import the array into the new Windows box.

One of those links should tell you. From memory, I think the N36L is also good to go but look at the documentation in the links.

Thanks for clarifying the situation; I'm sure it will help a lot of people in these forums. if you still have some of those links you found, I'm sure others would be grateful if you posted them.

Looks like only 1 drive is visable from the Sans Digital TR4M, so it's as if it's a regular single hard drive connected externally. Bummer. :( Looks like I would have to install a esata port multiplier card in the PCIx slot.


At least the DROBO-S is visable as 1 drive, but that's a premuim device.


I cannot believe I missed this post. I jumped on that Shell Shocker and figured I'd be good to go. Now I'll need an esata port multiplier card. This one is all on me though. Thanks John!

Hi, Hope someone can help me, seems I've bricked my N40L.

I followed all the instructions regarding the BIOS mod update, but after getting to the C:\ prompt and doing the restart my server is basically dead.

On power up the HP logo turns red for a second and then goes out, the power button is green, fans are all on, but the screen is just black?


Any idea what i could do to recover the factory BIOS or any other BIOS? I even tried doing the CMOS clear procedure by changing the jumpers on the board.


Any help would be appreciated.

Get a copy of the BIOS form the HP site.




Thanks, but I've tried this.


When using the USB stick, are you supposed to use the on board USB port?

What i don't understand is when I ran the mod, I could see it was doing something because of all the output to the screen. It did not take long until I saw the C:\ prompt, I removing the USB stick and did the restart. What is the actual procedure for powering down when you get to the prompt, hold the power button down till it turns orange or pull the plug?


I've followed the following forum too, but with no luck.



Is there any way to get back to factory defaults?

      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.

      Critical - HPE requires users update to this version immediately.

      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
