Thanks for the ideas, the easiest one would be down arrow twice, then enter, but how could I know when to do it since the whole booting process takes like 5 minutes and there is only a short window (5 seconds i think) until it automatically chooses the first option.
I will try the cfg edit, if I got it right I will have to add the lines you wrote to the beggining of syslinux.cfg, boot and install DSM, shutdown when done, replace syslinux.cfg with default one and restart the server. Is this correct?
@TBK
I have no idea how to use iLO RDP, is there a tutorial for using RDP to install XPEnology?
Thank you!
