Why is BIOS basemem detected > as 639K when my BIOS claims it has 640K? And what is RTC basemem? This is BIOS vs. CMOS value. Some CMOSs take over the final k or so for configuration data (??!?!?) but still report the machine having "640k". Search the mail archives in hackers -- there was a discussion on this a long time ago.
