Hi guys, I've been using this motherboard and I think is pretty cool but I have an issue with sleek keyboards (Apple slim keyboard wired, Logitech Illuminated keyboard) but none of them work with this motherboard, only work when the OS is already runing, so this means no BIOS access with any of this two keyboards, with Logitech Elite Keyboard I don't have this issue, so I hope to see a fix for this issue.
I'm using latest BIOS [SGP4510H.86A] 0121
I have the same problem with Logitech Illuminated Keyboard. I've found just one solution: You can enter the BIOS, if the keyboard will be connected to the one of internal USB-headers. But I think, that is not ok with DP45SG. If you update your BIOS to 0125 this solution will not work at all.
