Exception during the UEFI preboot environment. DellFormsProcessorDxe.efi

Question

Dell-EFI-Exception-DellFormsProcessorDXE.efi.jpg

Cannot enter F2 System Setup because it crashes. Want to change back to BIOS boot mode, but cannot get access to the menu that lets you choose BIOS vs UEFI for booting. By using the F11 menu, i can get the OS to boot up and even launch the lifecycle controller, but not everything works in the LC, even after flashing the latest combined 2.8.0 iDRAC+LifeCycleController update. For instance, an "Advanced" part of the LC hangs.

The system detected an exception during the UEFI pre-boot environment.

rip 78592CD3 DellFormsProcessorDxe.efi +010CD3 <-- Crash occurred here

There are no physical USB drives and this occurs whether or not virtual media is attached via iDRAC or not.

There is an unsupported DELL BOSS-S1 card installed with two approved blank unconfigured Micron drives. But it was installed long before this UEFI boot problem appeared. The Dell EMC Boot Optimized Server Storage-S1 or BOSS-S1 was not officially supported until the 14th generation, but i did not think it would be too difficult to make a bootable hardware RAID1 out of two M.2 SSDs on a PCI card. I am not 100% sure the BOSS-S1 is the problem, but have others had success with the BOSS-S1 in a R720 or other 12th generation PowerEdge? Is there a way to make this work short of forking over several hundred for a HighPoint SSD7103? I dont need speed as much as i need a mirror dedicated to booting the HyperVisor OS.

Hello I would start removing hardware to see if the issue changes. Since you can access the OS you could also re-flash hardware. Thanks

Also having this issue. Appears to be happening whenever the BOSS-S1 card is plugged into any of the PCI ports of the R720.

The BIOS seems to recognize the M.2. drives and booting works just fine, but attempting to access System Setup > Device Settings causes the same UEFI stack crash. It doesn't seem to matter which mode the system is in (BIOS or UEFI).

This is on BIOS revision 2.9.0.

Hi,   Unfortunately, 12G and 13G server are unable to support BOSS-S1 card.    https://dell.to/34HxOJf

Did you have it formatted for BIOS or UEFI? I am having the same issue and wondering if I install the OS on a different machine and then plug into thr R420 it will then boot?

DELL-Joey C · Answer

Hi @Troggie0092,   I doubt it would work, as R420 is not compatible with BOSS card. If you have a BOSS card to try, let's clear that doubt and let us know if it works.

Hi there

I have tried and every time I get this error. It's an unsupported BOSS card.
I have upgraded the firmware to 2.9.0 however I haven't upgraded the iDRAC or LCC firmware up until last night, do you think this would change my outcome?

Regards

DELL-Joey C · Answer

Hi @Troggie0092,   It looks like a incompatible hardware on the server, which UEFI BIOS is unable to identify, unfortunately. Hence, the BOSS card is not support by the server.

Troggie0092 · Answer

Is there a way to bypass it or at-least boot to BIOS instead of UEFI?

Troggie0092 · Answer

Thank you The error remains whether BIOS or UEFI modes

DELL-Joey C · Answer

Hi @Troggie0092,   Nop, that's not possible to bypass.    You can switch Boot modes in BIOS, under boot settings, though.

Hi, could you explain everything you changed before this error happen and please try to recover the old state from your system.   Regards Martin

Very similar is happening on FC630 with IDSDM Firmware Version 1.11-A02 and virtual media connected to any .ISO

Boots normal without virtual media connected. BIOS is latest version 2.19.0

Latest IDSDM 1.12-A03 version is available, but caused many headaches with intermittent boot failures (mirror corruption of sdcards) , so it was downgraded to resolve such.

In retrospect, maybe nothing to do with IDSDM but rather the Virtual Media function / BIOS. 🤷‍♂️

EDIT: Setting UEFI mode allowed boot from ISO virtual media.

Hello, I’m afraid I’m going to have to repeat what Joey said earlier.

“Unfortunately, 12G and 13G server are unable to support BOSS-S1 card.”

This also means = No Boss, No error message either.

Let us know if you have additional questions.
