+          The Extended Industry Standard Architecture (EISA) bus was
+          developed as an open alternative to the IBM MicroChannel bus.
+
+          The EISA bus provided some of the features of the IBM MicroChannel
+          bus while maintaining backward compatibility with cards made for
+          the older ISA bus.  The EISA bus saw limited use between 1988 and

+          cards, you need to say Y here and also to "CardBus support" below.

+          it here. The emulator will then "only" calculate with a 64 bit
+          mantissa and round slightly incorrect, what is more then enough
+          for normal usage.
+
+config M68KFPU_EMU_ONLY
+        bool "Math emulation only kernel"
+        depends on M68KFPU_EMU
+        help
+          This option prevents any floating-point instructions from being
+          compiled into the kernel, thereby the kernel doesn't save any
+          floating point context anymore during task switches, so this
+          kernel will only be usable on machines without a floating-point
+          math coprocessor. This makes the kernel a bit faster as no tests
+          needs to be executed whether a floating-point instruction in the

+config ADVANCED

+        ---help---
+          This gives you access to some advanced options for the CPU. The

+          it possible for you to improve performance somewhat if you know what
+          you are doing.
+
+          Note that the answer to this question won't directly affect the
+          kernel: saying N will just cause the configurator to skip all
+          the questions about these options.
+
+          Most users should say N to this question.
+
+config RMW_INSNS
+        bool "Use read-modify-write instructions"
+        depends on ADVANCED
+        ---help---
+          This allows to use certain instructions that work with indivisible
+          read-modify-write bus cycles. While this is faster than the
+          workaround of disabling interrupts, it can conflict with DMA
+          ( = direct memory access) on many Amiga systems, and it is also said
+          to destabilize other machines. It is very likely that this will
+          cause serious problems on any Amiga or Atari Medusa if set. The only
+          configuration where it should work are 68030-based Ataris, where it
+          apparently improves performance. But you've been warned! Unless you
+          really know what you are doing, say N. Try Y only if you're quite

+        bool "Use write-through caching for 68060 supervisor accesses"
+        depends on ADVANCED && M68060
+        ---help---
+          The 68060 generally uses copyback caching of recently accessed data.
+          Copyback caching means that memory writes will be held in an on-chip
+          cache and only written back to memory some time later.  Saying Y
+          here will force supervisor (kernel) accesses to use writethrough
+          caching.  Writethrough caching means that data is written to memory
+          straight away, so that cache and memory data always agree.
+          Writethrough caching is less efficient, but is needed for some
+          drivers on 68060 based systems where the 68060 bus snooping signal
+          is hardwired on.  The 53c710 SCSI driver is known to suffer from

+          Some Atari 68k machines (including the 520STF and 1020STE) divide

+          (up to 512MB) is the main memory; the ST section (up to 4MB) is

+
+          This enables support for using (parts of) ST-RAM as swap space,

+          performance if you have lots of alternate RAM (compared to the size

+          memory. ST-RAM will remain as ultra-fast swap space. On the other

+          for device driver modules (e.g. floppy, ACSI, SLM printer, DMA

+          (/dev/tty0) will still be used as the system console by default, but
+          you can alter that using a kernel command line option such as

+
+          If you don't have a VGA card installed and you say Y here, the
+          kernel will automatically use the first serial line, /dev/ttyS0, as
