Abstract: A portable multimedia device stores multimedia content and sets of user preferences (“settings”) for one or more users (karaoke participants), on a title by title basis, that the one or more users may wish to apply upon playback of the content. The content and settings are initially stored in the portable device with the use of a practice playback system. Once this is done, the portable device may be transported and connected to any performance playback system. The portable device and the performance system may be operated to select and play back any title of content stored in the device, applying the corresponding stored set of user preferences for the user.

Abstract: An adapter or add-in card for using in a peripheral component interconnect (PCI) computer includes a universal module which couples the card to the PCI bus. The module includes a set of selectively programmable configuration registers which are loaded by a microprocessor on the adapter. A circuit arrangement on the module issues a command which inhibits the PCI processor from accessing the configuration registers until fully loaded.

Abstract: An adapter or add-in card for use in a peripheral component interconnect (PCI) computer includes a universal module which couples the card to the PCI bus. The module includes a set of selectively programmable configuration registers which are loaded by a microprocessor on the adapter. A circuit arrangement on the module issues a command which inhibits the PCI processor from accessing the configuration registers until fully loaded. Another circuit arrangement presents the Expansion ROM base address register as a `read/write` register or a read only register with all bits set to logical "0 " to the PCI computer. If the Expansion ROM base address register is presented as a read only register with all bits set to "0 ", the PCI computer concludes that no Expansion ROM exists on the add-in card, and its contents are not shadowed into the memory of the PCI computer. This disabling of the Expansion ROM causes memory space to be conserved in the computer.
