There are known problems with some BIOSes and "USB Legacy" support.
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).
P.S. -- Why are you slamming keys during the bootup sequence? :-)
