ILO issues and HOT KEYS

If you get an ilo issue with a remote console - as i recently have - where it is stuck and not booting, but giving you Function key options (for example, F10 to enter sys maintenance mode - always a good idea) - then if function keys are not set up, you need to do it. Luckily, setting up hot keys is simple - just go to remote console > remote console hot keys, and you can set up your function key 'hot keys' there

FYI, I did an F10 and got into the GRUB menu and could then boot into linux, as opposed to windows (which is what the console was telling me it was configured as - even though I knew the OS was linux...........)
