Tower Plus EBT2250, BIOS level investigation denied
Hello Dell Community,
I’m a user of the Dell Tower Plus EBT2250 system (Core Ultra 9 285K).
I’ve been investigating an issue where the following PowerShell command:
Get-WmiObject -Class Win32_Processor | Select-Object VirtualizationFirmwareEnabled
consistently returns "false", even though virtualization is enabled in BIOS and the OS is Windows 11.
I contacted Dell Japan Support and received the following responses:
- No reproduction testing was performed on the actual EBT2250 model
- Dell does not recognize the possibility of BIOS/ACPI notification issues
- The issue is repeatedly attributed to “OS-level behavior” without technical evidence
- SSD upgrades and application dependencies were cited, though unrelated to this flag
- No response from Microsoft has been shared, despite blaming the OS
- All three suggested OS-level tweaks (VBS disable, registry, bcdedit) were tested with no improvement
- Despite this, Dell continues to deny any BIOS-level investigation
I view this not as a question of whether virtualization works, but whether the OS is receiving correct firmware-level notifications from BIOS, a structural issue. Frankly, based on the responses so far, I’m deeply disappointed and confused by Dell’s technical stance. It raises serious doubts about the company’s engineering integrity and its willingness to investigate low-level firmware behavior. Is this truly aligned with Dell’s global technical standards, or is this a limitation of regional support? I’m not asking for help here, I’m asking:
**Do other users find this level of technical support acceptable?**
**Has anyone experienced similar behavior on recent Dell systems?**
**Should BIOS/ACPI notification inconsistencies be taken more seriously by Dell engineering?**
Thank you for reading.

[Regarding DELL Support's Response to the VirtualizationFirmwareEnabled=false Issue]
I've been investigating a persistent issue on a DELL EBT2250 + Core Ultra 9 285K system, where the command `VirtualizationFirmwareEnabled=false` is returned—even though virtualization features are enabled in BIOS and functioning correctly (Hyper-V, WSL2, etc.). A clean OS reinstall did not resolve the issue.
This suggests a possible inconsistency between BIOS and OS-level virtualization signaling. However, DELL support ultimately responded with:
- A blanket statement that "it's due to OS behavior" without technical evidence
- A refusal to contact Microsoft, despite previously stating they could do so
- No disclosure that they had skipped the Microsoft inquiry until I pressed for it
- A strange pivot to NoxPlayer FAQs, which are unrelated to the core issue
This kind of response lacks technical integrity and places undue psychological stress on the customer. Some interactions even felt borderline harassing in tone and evasiveness.
It's now clear that DELL Japan support lacks both the technical capacity and the procedural transparency to handle this case. I will be shifting focus to direct inquiries with DELL US and Microsoft, and seeking collaboration from the community
