Modified BIOS for Microserver N40L enables hidden features

What if HP relase a new BIOS version tomorrow which fixes a bug or gives us more features on the N40L, would it be possible to flash the BIOS with this newer version? Or does the modified BIOS version in somehow prevent us from doing this?

If you flashed the BIOS with a newer HP version, you would have to go back and put the Mod BIOS back on, if that is what you want.

You can flash the BIOS at any time. Not all features may be available in the new OS if any new features require a new OS install but that should be rare.

Success! I have unlocked the hidden features in the BIOS by using diehard's modified BIOS version! :) Thank you!

 

I'm currently using a 120 GB Samsung SSD 840 Series (Model number: MZ-7TD120) on the optical drive sata port and have connected the optical drive to the E-SATA port, which now have changed to a ordinary SATA port thanks to the BIOS modification.

 

I'm installing Windows Server 2012 on my N40L now, hoping everything wil go smoothly in the installation.

Is it possible to run the following while running with hardware RAID?

  • 1 x SSD (on the SATA port which the ODD earlier used)
  • 1 x ODD (before the BIOS modification this port is was a E-SATA port, now it's configured to be a SATA port)
  • 4 x HDD (on the 4-slot bay for HDD's)

I tried to change the "SATA Controller mode" in BIOS from ACHI to RAID in order to be able to configure hardware raid. But when Windows Server 2012 tries to start it got an error and reboots.

 

When I change back to ACHI mode for the "SATA Controller mode" parameter in BIOS, I successfully boot Windows Server 2012 without any errors.

 

I don't want to use software RAID since it required CPU power, something which the N40L server doesn't have plenty of...

If you changed the Mode to RAID I would suspect that at the least you would have to install the RAID drivers and should probably reinstall your OS but Jump over to Sucessfully Enabled Port Multiplier on eSATA and Read Thread messages #1, 14, 28, 60 for a good flavor of what's going onover there. It's not good news for your case, In particular in #14 Alex says:

 

I forgot to mention one other important thing that I found:

  • The unlocked BIOS cannot boot if your SATA controller is in RAID mode. This is not an issue if you're running in AHCI mode, and it's not an issue with the official BIOS.
  • I've noticed that the RAID BIOS drive enumeration process never shows up during the boot cycle. This is something to be aware of.

I believe this means that if your server is set to RAID mode, you will not be able to boot your system if you flash the unlocked BIOS. I didn't spend any time diagnosing this problem because my goal was to get port multiplication working.

 

This is not destructive, because you can simply just flash the official BIOS back.

As is indicated in the posts Joe_Miner referenced, you cannot simply switch the BIOS from AHCI to RAID, or vice-versa, as you like. If you install an OS with the BIOS in AHCI, it will format the drives in a way that will make the system unbootable if you switch to RAID. There is a registry hack that can get around this, but the point is simply that you really should choose which one you want before you install the OS.

      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.

      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
