Subject: BIOS basemem (639K) != RTC basemem (640K) ...

This message appears during boot up (on every version I've tried so far I
think : 2.1.x, 2.2R, 3.0):

BIOS basemem (639K) != RTC basemem (640K), setting to BIOS value

I have been assured the message is harmless, but I am (as what FreeBSD'er
would not be!) curious about what it means.  Why is BIOS basemem detected
as 639K when my BIOS claims it has 640K? And what is RTC basemem?

Any information gratefully received!
