![]() I also tried a more recent Turtle Beach Santa Cruz (Crystal chipset) in DOS once. You can use the command "LH AU30DOS.COM" to load the emulator - doing so only takes 1 KB of your base memory. Otherwise no software General MIDI is available. It is one of the few to have a functional wavetable daughterboard header in DOS. (I only used SB-PCI 128 and SB-Live!).Īureal Vortex 2 does Sound Blaster Pro DDMA emulation. It supports OPL-3 and General MIDI music with a software driver. As far as I know it is all roughly the same program, just that Creative replaced the Soundscape emulation with Sound Blaster 16 emulation. The related software was bought by Creative Labs and adjusted for their AudioPCI-clones, SB-Live! and Audigy-1. CCLS provides a hardware interface that supports a Sound Blaster Pro-compatible interface in addition to FM and joystick interface.Įnsoniq AudioPCI was the first with a "pure" DOS DDMA emulation. Some of Crystal Semiconductor's audio chips come with what they call CCLS (CrystalClear Legacy Support). Roughly the same time period applies to DDMA support on motherboards. You should only expect to find such support on PCI sound cards sold new up until about 2001. DDMA support is more common than PC/PCI support. Such emulation methods *must* be supported by both the sound card and the motherboard for the method to work. your PCI sound card must support legacy DOS audio. If your PC's South Bridge supports either of these, your DOS audio-supported PCI sound card will work under DOS. There are two emulation methods that are sometimes employed to do this in pure DOS:ġ) DDMA (Distributed DMA) (EDIT: combined with an IRQ related method)Ģ) PC/PCI using a physical SB-LINK connection. They use typical ISA channels for sound data: IRQs, I/O addresses, and DMA channels.Ī PCI sound card's DOS driver must setup routings to intercept the ISA-style commands/instructions for playing sound and music and pass them through to the PCI hardware. Most DOS programs/games are designed to only access sound cards on the ISA/ EISA bus. It does not include running programs in a DOS shell or command interpreter from Windows, nor booting to DOS from Windows 95 or 98 ** ** Note: This article refers to the use of PCI sound cards in DOS versions 3.3 up to 6.22. ![]()
