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
|
|
1995 when it was made obsolete by the PCI bus.

|

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

kernel should be executed or not.

to destabilize other machines. It is very likely that this will

---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

|
|
If you say Y here, it will be possible to use a serial port as the
|
|
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 (lilo or loadlin) about how to pass options to the
|
|
kernel at boot time.)
|
|
|
|
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
|
|
system console.
|
|
|
|
If unsure, say N.
