  73           The EISA bus provided some of the features of the IBM MicroChannel
  74           bus while maintaining backward compatibility with cards made for
  75           the older ISA bus.  The EISA bus saw limited use between 1988 and
  76           1995 when it was made obsolete by the PCI bus.

 361           The 68060 generally uses copyback caching of recently accessed data.

 364           here will force supervisor (kernel) accesses to use writethrough
 365           caching.  Writethrough caching means that data is written to memory
 366           straight away, so that cache and memory data always agree.
 367           Writethrough caching is less efficient, but is needed for some
 368           drivers on 68060 based systems where the 68060 bus snooping signal

 588           If you say Y here, it will be possible to use a serial port as the
 589           system console (the system console is the device which receives all
 590           kernel messages and warnings and which allows logins in single user
 591           mode). This could be useful if some terminal or printer is connected
 592           to that serial port.
 593
 594           Even if you say Y here, the currently visible virtual console
 595           (/dev/tty0) will still be used as the system console by default, but
 596           you can alter that using a kernel command line option such as
 597           "console=ttyS1". (Try "man bootparam" or see the documentation of
 598           your boot loader (lilo or loadlin) about how to pass options to the
 599           kernel at boot time.)
 600
 601           If you don't have a VGA card installed and you say Y here, the
 602           kernel will automatically use the first serial line, /dev/ttyS0, as
 603           system console.
