That your BIOS is stealing 1 KB off the 640 K basemem to store its
disk table there (for user-type disk [47]). Not much to care about
except that it would be an additional kilobyte invisible for DOS
itself. More modern BIOSes do this by putting the table into the BIOS
stack.
This is only a hint, and benign in the above case. If the numbers
would have been 256K vs. 640K, it might have been serious though.
