.Sh CAVEATS
|
|
Currently it is up to the user to ensure that given memory board
|
|
is not used by the kernel as normal RAM.
|
|
It is usually safe to pass the
|
|
.Ic -n0
|
|
and
|
|
.Ic -p
|
|
parameters to boot loader.
|
|
.Pp
|
|
If the kernel is compiled without the
|
|
.Nm
|
|
driver, it is possible to use Zorro III
|
|
memory boards as normal RAM in some configurations.
|
|
However, this might have severe performance consequences.
|
|
It is advised to use Zorro III memory boards as swap where possible.
