Using filters in a driver map
The purpose of a filter in a driver map is to automatically determine which set of
drivers to make available to the Windows setup program (or mini-setup program
in the case of a Portable-Sysprep Image) for a specific target computer. The filters
provided with the ImageUltra Builder program enable you to query for the
machine type, machine type and model number, platform (desktop or mobile), and
whether or not the target computer is a Lenovo branded computer. To reduce the
number of menu items and filters in a map, you can provide multiple drivers and
let the Windows setup program (or mini-setup program) sort them out based on
Plug-n-Play hardware detection.
You can also create your own Win32 filters if you need to query for some other
hardware condition. Filters are Win32 programs that run during the installation
process. In most cases, filters query the computer BIOS for information, but filters
can query any installed hardware that stores identification information in a ROM
or EEPROM module.
When using filters in a driver map, filters are assigned to menu items, not to
modules. The behavior of the filter is controlled through the Conditions tab of the
Menu Properties window. If you assign multiple filters to a menu item, you define
whether only one of filters needs to be satisfied or if all of the filters need to be
satisfied to use the module.
When a filter is assigned to a menu item, a small condition icon (question mark on
a yellow, square background) is displayed in the lower-left corner of the
menu-item icon. The following illustration shows the tree structure of a
device-driver map that has a filter assigned to each menu item.
