Combine Filters Using: The default is to have filters ANDed and filter sets ORed. You
can use this field to reverse these Boolean functions for the filters and sets.
Using OR for filter sets means that all filters in a set must be matched to apply the rule, but
any of the sets can be matched to apply the rule.
Using AND for the filter sets means the reverse. At least one filter in each set must be
matched for the rule to be applied.
An expression consists of a criteria option, operator, and value, and in some cases, a qualifier.
For example:
RAM (in MB) =< 512 MB
RAM (in MB)
If necessary, you can use NOT (in the first blank field with a down-arrow) to perform a logical
negation of the expression. For example:
NOT RAM (in MB) =< 512 MB
In the above example, the rule is applied only to devices with less than 512 MB of RAM.
You can use more than one expression for the rule. For example:
RAM (in MB) =< 512 MB or
Hard Drive Size (in MB) < 20 GB
Hardware Type displays in the criteria options list only if you have previously configured a
custom hardware type
configuration page.
IMPORTANT: Be aware of the possibility of creating conflicting filters or rules. For example,
if you specify a RAM condition in multiple filters, make sure the effective logical operators
where each is configured make sense for the megabyte values that you enter. In other words, if
two filters are both required (ANDed), you would not want one filter to require exactly 512 MB
of RAM and the other to specify at least 512 MB of RAM.
5 Click OK to exit the dialog box and place the new hardware rule into the Hardware Rules list
box on the Preboot Services configuration page.
Rule Logic
A rule is made up of one or more filters that are used to determine whether a device complies with
the rule. The Rule Construction dialog box begins with one empty filter. A device must match the
entire filter list of a rule (as determined by the logical OR nd AND operators that are explained
below) for the rule to apply to the device.
A filter is a row of fields providing a condition that must be met by a device in order for the bundle
to be applied. For example, you can add a filter to specify that the device must have exactly 512 MB
of RAM in order to be accepted by the rule, and you can add another filter to specify that the hard
drive be at least 20 GB in size. There is no technical limit to the number of filters that you can add in
the rule, but there are practical limits, such as:
Designing a rule that is easy to understand
Devising the rule so that you do not accidentally create conflicting filters
Being able to view the dialog box as it grows in size because of the filters and filter sets that
you add
