Said BIOS option allows a USB keyboard and mouse to be emulated as PS/2 for operating systems which lack a USB stack, such as MS-DOS -- and more importantly, bootloaders! The FreeBSD bootloader only understands AT/PS2 keyboards, which is why that BIOS option is needed. Can you confirm this problem happens when using a PS/2 keyboard? If so, then the issue is probably in the bootstrap code somewhere. If the problem goes away when using a PS/2 keyboard, then the problem is either a BIOS bug (likely in this day and age), or a compatibility issue with the model of USB keyboard you have (not all USB keyboards are identical in behaviour).
