Thread: Making sound card detectable in bios

I had included sound card on motherboard. It is devoted sound card which is utilized to play sound for home theater system. But I unable to find it in device manager for some cause. I attached similar and problem surely lies in bios settings. How to solve this problem? Please help me.

1) The steps to add pci device in system. Add part of tools in system. Then system BIOS start PnP BIOS. PnP BIOS scans PCI bus for hardware. It does this by sending signal to any device linked to bus, asking device who it is. Sound card take action by identify itself. Device ID is sent back across bus to BIOS. By this way sound card visible in bios.

2) In this procedure of PnP BIOS confirm ESCD to see if arrangement of data for sound card is before present. As sound card was installed, there is no available ESCD record for it. PnP BIOS allocates IRQ, DMA, memory address and I/O settings to sound card and saves data in ESCD.

3) In many cases, XP will identify device, find and load needed drivers, and you prepared to go. If not, Found New Hardware Wizard appears. This undeviating to install drivers of sound card. After driver is installed, device must ready for use. Few devices need that reboots PC earlier than utilize them.

4) As sound card is in record mode, bus organizer assigns high priority to data out from it and sends sound card data above Bus Bridge to system bus. System bus saves data in memory. After recording is finish, take conclusion whether data from sound card is saved to hard drive or retained it.
