### MAD16.ADD Device Driver Overview

All device configuration is performed through software programmable settings. Base I/O address and DMA and IRQ selections for CD-ROM and audio are initialized from software through the MAD16.ADD device driver. There are no jumpers.

Once enabled, existing device drivers can be used to perform audio and CD- ROM actions. For example, existing AD1848 business audio device drivers can be used on configurations with the AD1848. Existing CS4231 device drivers can be used in board configurations that have the CS4231 device. Likewise, the MAD16 device can be set to enable Sony31A, Mitsumi, Panasonic or IDE CD -ROM interfaces. An appropriate CD-ROM device driver is loaded later to perform CD-ROM activities.

The job of the MAD16.ADD is to initialize the device.
