what are AD1846 and 82c929a chips responsible for?
Does the DreamBlaster X2/X1/S1 work with this 82c929A chip in general midi under DOS? will I need any additional drivers to set it up?
AD1846 is the Windows Sound System codec.
82C929A has SB emulation, mixer, MIDI UART, game port and acts as a glue logic interface between OPL3 and WSS (AD1846), including control for external CD ROM interface buffers (yeah, it has logic to control those buffers, but it can't sit between say IDE CDROM and ISA BUS, because IDE bus is just buffered ISA bus).
So I have no personal experience but since it provides the MPU midi interface at standard ports, it should work just fine with DreamBlasters. It may need some software to configure the card to enable and set the MIDI port address if it defaults disabled or wrong address. It appears to default the MIDI interface enabled to port 330h, IRQ 9. But it's possible you may want to disable all other interfaces to have compatibility with another sound card, or turn volumes of unused interfaces down. It does have genuine OPL3 FM though!
