	  SPARC is a family of RISC microprocessors designed and marketed by
	  Sun Microsystems, incorporated.  They are very widely found in Sun
	  workstations and clones. This port covers the original 32-bit SPARC;
	  it is old and stable and usually considered one of the "big three"
	  along with the Intel and Alpha ports.  The UltraLinux project
	  maintains both the SPARC32 and SPARC64 ports; its web page is
	  available at <http://www.ultralinux.org/>.

	  system console (the system console is the device which receives all
	  kernel messages and warnings and which allows logins in single user
	  mode). This could be useful if some terminal or printer is connected
	  to that serial port.

	  Even if you say Y here, the currently visible virtual console
	  (/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
	  "console=ttyS1". (Try "man bootparam" or see the documentation of
	  your boot loader (silo) about how to pass options to the kernel at
	  boot time.)

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

	  If unsure, say N.

	  To use your PC-cards, you will need supporting software from David

	  CONFIG_PCI is needed for all JavaStation's (including MrCoffee),
