Nope, there isn't necessarily needed such a crystal. It's the input
frequency of the timer circuits, and normally derived from the 14.XXX
MHz bus clock (BUSCLK/8).
Is your DOS internal clock (not the CMOS one) also wrong? It's hard
to believe that this is a FreeBSD only problem. I suspect you've got
something wrong with your BIOS/Chipset setup.

Never trust an operating system you don't have sources for. ;-)
