Most AT/386-clones accept 16MB of physical memory (with 1Mb DRAM devices).
This is divided in four banks, 4 MB each.  With 256Kb DRAM devices this
translates to four banks, 1 MB each.  Now you have the banks 0 (the first MB)
and 1 (the second MB) populated.  Thus banks 2/3 are marked as disabled, as
there is no memory in their area.  So, the BIOS is configuring the memory
all right.
