How to remotely bypass POST Error without physical access?

[feicipet]

Hi,

My HP Z6 G4 has been recently going unresponsive and when I reboot the machine, I would see the POST error "928-Fatal PCIe error. PCIe Surprise Link Down error detected on Slot 0". I've already tried swapping out all PCIE cards that I have on it to no avail thus far. But let's assume that I'm ok to put up with the intermittent downtime for the time being. 

MY HP Z6 G4 is running in my home lab now, but I'm not always home and I would at least be able to restart the machine remotely whenever it hangs. I've already enabled Intel AMT and I'm able to remotely access the AMT port and power cycle the machine. However, whenever the machine had previously hung due to the 928 error, it would always boot up with the warning informing me about the POST error and I need to press enter on a physical keyboard to acknowledge the error in order to get past the POST bootup sequence. This makes it impossible for me to restart the machine remotely as it would always get stuck at the POST error warning. 

Is there a way for me to set a BIOS setting to just not show the warning? I've been mucking around in the BIOS settings but couldn't find anything that seems to fit. This is making me extremely cagey as I'm planning to fly back to my folks' home for X'mas in a couple of weeks' time and not being able to restart the machine is gonna keep me up at night.

 POST error "928" is almost always caused by a defective or failing pci-e card or one that is not properly inserted

since you have swapped cards to no effect i suspect it's not due to a improperly inserted card, that leaves a defective or failing card or a incompatibility between inserted cards

you would be better served determining the root cause rather than ignoring the error which can cause numerous other issues with the system's installed OS

Hi,

I totally understand that it's important to find out the real root cause of the issue. I would happily sit in front of the server for the next few weeks troubleshooting this if it wasn't for the fact that it's X'mas next week and I do need to visit my folks once in a blue moon. So just for the time being, if there's a way to just allow me to get through this by forcing a restart whenever it happens, it would just make life a bit easier for me over the next couple of weeks. Appreciate any help.

thanks

try the HP "BCU" application which is a windows based bios config application it will/might allow access to some settings that are not shown in the bios GUI  such as booting without a video card

you can save the existing bios config as a text file, edit it and then read it back in to set undocumented/hidden bios settings
