+# You may now load up to 4 optional ROM images. Be sure to use a
+# read-only area, typically between C8000 and EFFFF. These optional
+# ROM images should not overwrite the rombios (located at
+# F0000-FFFFF) and the videobios (located at C0000-C7FFF).
+# Those ROM images will be initialized by the bios if they contain
+# the right signature (0x55AA).
