  390. inside your box. Other bus systems are PCI, EISA, MicroChannel
  391. (MCA) or VESA. ISA is an older system, now being displaced by PCI;
  392. newer boards don't support it. If you have ISA, say Y, otherwise N.

  504. If you say Y here, it will be possible to use a serial port as the
  505. system console (the system console is the device which receives all
  506. kernel messages and warnings and which allows logins in single user
  507. mode). This could be useful if some terminal or printer is connected
  508. to that serial port.
  509. Even if you say Y here, the currently visible virtual console
  510. (/dev/tty0) will still be used as the system console by default, but
  511. you can alter that using a kernel command line option such as
  512. "console=ttyS1". (Try "man bootparam" or see the documentation of
  513. your boot loader (lilo or loadlin) about how to pass options to the
  514. kernel at boot time.)
  515. If you don't have a VGA card installed and you say Y here, the
  516. kernel will automatically use the first serial line, /dev/ttyS0, as
  517. system console.
  518. If unsure, say N.
