We use Mercedes Retail Data Storage 1 in our workshop.
This product is no longer in production and will no longer be supported by Mercedes in the future.

RDS specification:

  • ASUS RS100-E9 and ASUS P10S-M-DC
  • Intel Dual Core I3-7100 3.90GHz
  • 8GB ECC DDR4 2400MHz
  • 4TB SATA III Seagate Skyhawk 3.5

This hardware is not very productive, but it can be useful for a second life.
Unfortunately, BIOS and BMC are locked.

Does anyone have any ideas on how to reset the system?

A quick update from my side.
I couldn't flash the attached BIOS, so here's what I did.

I went to the ASUS website and downloaded the BIOS for the P10S-M-DC, created a bootable FreeDOS USB stick using Rufus and copied the BIOS and "bupdater.exe" (included in the zip file), booted without a hard drive from USB only and ran "bupdater.exe /i<biosname>" (Note: there is no space between /i and the BIOS name, you need to keep it). After that it flashed and stayed unlocked.
Same problem.
I contacted the provider, but he asks for more than 250 euros for unblocking.
If you have any advice, let me know.

Try checking this.

  • Boot by pressing/holding F2 to enter BIOS/UEFI
  • When the password entry window appears, press Alt + R
  • A window will appear for entering the rescue password in the YYYY-MM-DD format

Unfortunately, the rescue password changes every day.
Here are some passwords for 2004 that should work for 2024 as well, but you can also try changing the date in the OS.

Code: 
2004-03-11 DHL1AHL0
2004-03-12 BAB0C1AL

And to reset the BMC you can use the IPMI tool from Super Micro, since they used ASUS IKVM. There should also be a copy of this tool on some CD that came with the hardware. With IPMI there should be one command from CMD to set a new password.

Not suitable for server motherboards.

Ok. Since I was sure you reset the CMOS, I would suggest using an old method that worked on some older servers.
You have a P11 or something like that motherboard on this server. Most likely a P11-M4. To reset the BIOS admin password, you just need to remove the CMOS battery for a while.
Have you tried that?
As for iKVM, I have an iKVM9 model and I'm pretty sure resetting the password should be possible via the IPMI tool.

I open the case and there is no battery. The slot is empty.
When I press Alt + R, nothing happens, just * appears in the "Enter password" window.

No battery in the slot? Very strange. I checked the documentation for this motherboard, and there should indeed be a regular 2032 battery, and the password reset is done by resetting the CMOS. Maybe you have the password somewhere else, for example on the HDD?

Hi startronic, if you find anything, let me know. I contacted them and they want me to send it back to Germany.
The Alt + R key combination on the screen does not work, apparently it is somehow disabled.
I also tried resetting the password using the jumpers on the motherboard, but that doesn't work.
And for some reason RDS doesn't use the CMOS battery.
It looks like they set their own default BIOS settings in the firmware that force the password even after a reset.

Can you post a picture of the motherboard?
Maybe something has changed there and it will be visible. Good quality is needed, best if it is done with some camera, not a phone.
Of course, if there is some kind of sticker with a MAC address, then it can be covered up.
It's strange that there is no battery. Maybe something was modified.
BIOS modifications are quite rare, but you can try to compare it with a clean original when someone provides a dump from their board.
You can also check your BIOS version and see if that version is listed on the ASUS website.

If something else, then at least write the version number.
