P/I-P55SP3AV User's Manual There are external Speaker, Microphone and Line-in jacks as well as the volume control in the mounting bracket of the AV689 audio/ display port card that comes with the mainboard. CD-ROM audio and Wave Table daughter-card connectors are mounted on the AV689. The,ESS AudioDrive chip supports third-party Wave Table cards from several vendors, including Turtle Beach and Creative Labs. On-Board Video Display The onboard SIS video display uses a either 1MB or 2MB of system DRAM as display memory to support multiple resolutions and color depths. You set the display memory size from the ChipSet Features section of the BIOS Setup utility. See that section in Chapter 3 for more information. A standard 15-pin VGA port is mounted on the AV689 audio/display port card that comes with the mainboard. The port card plugs into the connector between ISA slots Slotl and Slot2. An optional VGA port-only card is also available. SCSI BIOS Firmware & The Optional SC-200 Controller Card This mainboard has on-board NCR SCSI firmware recorded in the BIOS flash ROM chip that supports the NCR 53C810 PCI Fast SCSI2 controller. There is an optional SCSI controller card, the SC-200 that uses this firmware. The NCR SCSI controller is a full 32-bit PCI DMA bus master and supports the ASPI and CAM standards. You can connect a chain of up to seven devices to the SCSI interface. The SC-200 SCSI interface card provides both internal and external connectors. There are details on this card and how to connect SCSI devices to it at the end of Chapter 4. Two floppy disks with support drivers come with the SC-200 card. There is detailed information about the drivers in "ReadMe" files on the disks. There is more information about these disks in the section on "SCSI BIOS & Drivers" in Chapter 3. 1-14
