  77           bus while maintaining backward compatibility with cards made for
  78           the older ISA bus.  The EISA bus saw limited use between 1988 and

 364           The 68060 generally uses copyback caching of recently accessed data.
 365           Copyback caching means that memory writes will be held in an on-chip

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

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