Hi Intel Support Community,
I recently bought a Desktop Board DH87RL to build a new pc. This mainboard has only usb ports (none PS/2). I use a USB keyboard, but an issue exists:
1. Turn On the pc.
2. BIOS splash is shown (I have a couple seconds to press functions keys to activate BIOS, Boot Device Menu, after that (3-5 secs) and though BIOS splash continues visible the usb keyboard doesn't respond until SO loads, it prevents me activate and use F8 SO Menu (Safe mode, Repair etc.) and other DOS pre-load SO notification screens.
2.1 In BIOS, keyboard and mouse work fine.
3. After SO has loaded keyboard and mouse work fine, too.
I tested using Genius and HP usb keyboards with identical behaviour.
eThanks in advance for your help
I forgot: I've updated the BIOS to https://downloadcenter.intel.com/SearchResult.aspx?lang=eng&ProductFamily=Desktop+Boards&ProductLine... BIOS Update [RLH8710H.86A] 4/26/2013 0317.
USB legacy is Active in BIOS.
This behavior may be related to Fast Boot in your system:

One thing I would like to check is, what happens if instead of pressing F2 when prompted, you start tapping the F8 key?
I'm afraid Fast Boot is not an option, Fast Boot in BIOS is disabled (not checked). Also I've tried several times since num-lock is on tapping the F8 key, but boot continues with keyboard and mouse inoperative.
In some boot programs like Seagate's DiskWizard the keyboard and mouse don´t work, because of that I can't use it.
Can you provide the full model of the keyboard and mouse you are testing with? Are these USB 2.0 or USB 3.0 devices?
Were they working during the operating system installation? Did they ever worked with a previous BIOS version? Or have you tested other USB ports in the system?
Is there a USB front panel connected? If so, is there any difference if you test the system with this device disconnected?
Additionally, please use the Intel® System Identification Utility using the following site:
That will generate an 8 digits code called Report Reference ID. Please let us have that code, this will provide us information on what is being detected on your system.
