SUPPORT COMMUNICATION- CUSTOMER ADVISORY

Document ID: c04045903

Version: 1

Advisory: HP Z1, Zx20 Workstations - 6 Beeps After Changing BIOS Settings

Notice:: The information in this document, including products and software versions, is current as of the release date.The document is subject to change without notice.

Release date : 12-Dec-2013

Last updated : 27-Jun-2018

DESCRIPTION
HP Workstation boots with 6 beeps and no video following changes in the F10 setup utility.
Symptoms:
After changing and saving one of the following two settings in F10 setup:
1. Security / Secure Boot Configuration / Secure Boot -> Enabled
2. Advanced / Device Options / Video Option ROMS -> EFI
The system may produce 6 beeps on reboot, and will no longer show video on screen or load the operating system. There will appear to be no way to return to the F10 setup menu and change the settings back.

SCOPE
Information in this document applies to the following:
Systems:
  • HP Z1 Workstation
  • HP Z220 Convertible Minitower Workstation
  • HP Z220 Small Form Factor Workstation
  • HP Z420 Workstation
  • HP Z620 Workstation
  • HP Z820 Workstation
Operating Systems:
  • Non-OS Specific
RESOLUTION
The issue occurs because the video card ROM firmware is not UEFI compliant. When the system has been set to only boot using a UEFI compliant video ROM, and no UEFI compliant video ROM is available, the system is unable to activate the video card.
To resolve the issue, use the "Clear CMOS" button located on the system board. The exact location of the button varies slightly by workstation and is documented in the diagram on the inside of the side panel as well as in the service manual.
NOTE: Clearing CMOS will return all BIOS settings to default settings. Any customizations will need to be re-entered and saved.
