options optlid
Compile the listed options into the system. Options in this list are separated by commas.
There is a list of options that you may specify in the generic makefile. A line of the form
'options FUNNY,HAHA' yields -OFUNNY -OHAHA to the C compiler. An option may be
given a value, by following its name with
'='
then the value enclosed in (double) quotes.
None of the standard options use such a value.
contil kerne/f:Jame conM_clau4e4
Specifies a bootable system image; multiple boot able images may be specified in a single
configuration file. Here kernelname is the name of the loaded kernel image (normally,
vmunix). The conM_clau,e, specify at minimum the root device, and may also specify the
swap device. If you are using GENERIC as your system identifier (described above), or if
you customized your identifier and also included an options
GENERIC
line, then your
confiu_clau.e may legally be swap generic. In any other case, you must specify at least
your root device. For example, if you are configuring a kernel for a Sun 100U, and your
ident line looks like this:
ident
"~'1YI00"
your contil line might look like this:
config vm unix root on xy
4.3.12.4.2. Device Description Lines
The second class of line in the configuration file describes what devices your system has and
what they are connected to (for instance, I have a Xylogics xy450 on the Multibus). The device
description lines for all supported devices are given in the section 4 pages of the Sun Sudem
Interlace Manual; see the 'synopsis' section of the entry for each device.
Each device description line has the foHowing format:
de"_twe de,,_name at con_de" more_,·nlo
The meaning of the fields is:
De"_twe
is one of controller, tape, disk, device, or pseudo-device. These types have the follow-
ing meanings:
controller
is a Multibus disk controller or a Multibus tape controller.
disk or tape
are devices that are connected to a controller.
device
is something which plugs into the Multibus, like a cartridge tape interface.
pseudo-device
is something which should be conditionally loaded, but is not really a device. Current
examples are the pseudo-tty driver and various network subsystems. For pseudo-
devices, more_inlo may be specified as an integer, that gives the value of the symbol
defined in the header file created for that device, and is generally used to indicate the
number of instances of the pseudo-device to create. If you load a subsystem you may
find it necessary to enable conditional code using an options specification.
