-	<answer>
-	  <para>Due to the manner in which &os; gets the memory size
-	    from the BIOS, it can only detect 16 bits worth of
-	    Kbytes in size (65535 Kbytes = 64 MB) (or less...
-	    some BIOSes peg the memory size to 16 MB).  If you have
-	    more than 64 MB, &os; will attempt to detect it;
-	    however, the attempt may fail.</para>
-
-	  <para>To work around this problem, you need to use the kernel
-	    option specified below.  There is a way to get complete
-	    memory information from the BIOS, but we do not have room in
-	    the bootblocks to do it.  Someday when lack of room in the
-	    bootblocks is fixed, we will use the extended BIOS functions
-	    to get the full memory information... but for now we are
-	    stuck with the kernel option.</para>
