I have a very specific problem. I built a server with S5520HC and install Novell, I have found that the system can not install the keyboard driver. On closer investigation I discovered that the BIOS shows the detected USB keyboard even when it is not no connection. Therefore, if a join, see 2 keyboard and therefore occurs when trying to install the OS drivers = it's problem. I've tried different keyboards, even USB/PS2 reduction,u pdate BIOS to latest version .... result still the same. I tried to find an answer to Google, but in vain. I have a little concern that the board is faulty. Will you help? Please to email - firstname.lastname@example.org .
