Having looked high and low I can't find any info on how to change the boot logo. All the OEMS have replaced it with their own brand logo ie. Dell, HP, Sony etc so as its shown immediately after UEFI kicks in you would be forgiven for thinking you were looking at a traditional BIOS in mid POST. This of course is partly why new machines seem to start so quick. I know it's still early days but if anyone knows how to customise it or knows of any software capable of doing so I would be very grateful. Thanks.
