I have supermicro server running Grub 2.02 BETA 2. I kind of inherited this box, so I am kind approaching things gingerly. The box supports ONIE and I want to install a new image, but the first thing I would like to do is to get to the Grub menu.
I think it is worth mentioning that I am accessing the console via IPMI. For long story short, I have tried holding down the shift key when the Grub Loading message appears. I have tried hitting C. ESC, and Spacebar and can't get the menu to appear.
Some more background, It turns out that there is no /etc/default/grub file, but there is a /grub/grub.cfg
I was able to go into the /grub/grub.cfg and change the timeout=5 to timeout=30 and it does affect the time that the message is displayed.
I started wondering if I could be dealing with some artifact of how the supermicro IPMI handles a held down Shift key?
If anyone has any ideas on how to force the Grub menu to appear using the .cfg, I think that would at least get me going, but solving the case of the menu not appearing based on keystroke would work as well.
