Being unable to access the BIOS is normally the result of upgrading from Legacy BIOS to UEFI.
This can be corrected by resetting the CMOS Battery on the motherboard of the PC Module
For PC Modules included with the 5000 series panels, the CMOS battery is attached to the motherboard with a 2-pin clip and tucked underneath the motherboard. This connection can be located in between the motherboard and the power board. (If the connection is not immediately visible on the top-side of the motherboard, then it is located on the underside and will require either a pair of curved tweezers, or by removing the motherboard from the PC Module case.) To reset the battery, simply disconnect the 2-pin clip from the motherboard, wait 10-15 seconds, and then reconnect the 2-pin clip.
For PC Modules included with the 6000 series, the CMOS battery is located on the motherboard, typically located underneath the CPU Cooling fans. Simply remove the battery for 10-15 seconds before reinserting it.
