HP Z2 G5 workstation ( SFF )
Linux

HP case Number:  case: 5061554158    -  On New HP Z2 G5 workstation - Legacy Boot mode is unavailable and Option ROM Launch Policy menu item is missing. This is effecting our ability to deploy Linux workstations. The Option ROM Launch Policy menu item is visible on the older HP Z2 G4 workstations.  Having this option available appears to be the key to allowing us to boot the workstation in legacy boot mode ( Currently required in order to image  CENTOS 6 Linux workstations.  A bit disheartening that we can't see this option.

 

The HP Z2 G5 Maintenance guide taks about the legacy boot option being evailable.  HP have been saying it's not available on the Z2 G5. 

 

1. HP Advice:  " This model does not support Legacy boot, if user needs to install Linux or need support for Graphics or any other hardware devices that are not Secure Boot compatible , then need to disable Secure Boot in BIOS "

 

Not sure which is correct advice.  have disabled secure boot, however that did not help make the legacy boot devices visible in the boot  menu.

 

We have been procured these devices on the basis they provide this option.  Additionaly, we have referenced the user manual which referes to legacy boot mode as being available for this model (Z2 G5).  Please refer to the below which has been previously communicated.

HP Z2 Small Form Factor G5 Workstation

REF:  https://support.hp.com/au-en/product/hp-z2-small-form-factor-g5-workstation/34407171/manuals

 

I'm trying to boot a legacy USB, however it can't see the USB device.  i.e. it the legacy USB doesn't appear in the boot menu.  Only the UEFI USB book option appears.

 

Any advice on which info is correct  i.e. 

1. The HP advice ?

2. The HP Z2 G5  Maintenance and Service Guide    REF: http://h10032.www1.hp.com/ctg/Manual/c06908421.pdf

3. Other ?

 

Thanks

I am sad to see that there are no responses to this post. We just got a large batch of these workstations along with the G4 models. We can no longer image the machines using PXE boot. We previously would have to Enable Legacy / Disable Secure Boot from Bios > Advanced and this is no longer an option on the G5 models. F12 during start up does nothing. In the boot order, there is only the Windows boot manager, USB and DVD. Is there no way around this? I will send these computers back in a heartbeat.
