This article describes how to specify a specific or third-party hardware abstraction layer (HAL) during Windows Setup.

Selecting a specific or third-party HAL during Setup should be necessary only if you have a HAL provided by a third party, or if Windows Setup does not detect your hardware correctly.

Note This procedure works only when installing from a CD-ROM. When installing from setup boot floppies, a problem in the installation program prevents the installation of a third-party HAL.
