![]() Here's a list of motherboards and sound cards that have the Creative SB-Link header (or pads exist for you to solder a 5-pin header to), but there are more dated in the 1998 - 2000 era that do exist:ĮSS Solo 1-chip cards (some variants with ES1938s) ISA Sound Cards are probably a fine, if not better, approach. PCI Soundcards for Ultima 7 (note: external link) Here is an additional read on this topic, aimed at Ultima 7 players: I've got some perfectly tweaked DOS machines that run it fine. With either umbpci.sys or emm386.exe, I can load it high. The best compatibility I've achieved with PCI is an Aureal SQ2500 sound card with my Roland SCD-15 daughterboard. General MIDI in DOS can only be achieved when utilizing an external MIDI device. As a bonus this particular card has an integrated hardware OPL-3 for music. This setup failed with only one game so far (Quarantine). I have only used it with a Yamaha YMF724-based sound card on a BX440 motherboard. I have seen it supported on the AWE-64 and ESS Solo-1 sound cards. It works by connecting the PCGNT# and PCREQ# pins on theĪudio chip to the appropriate pins on the motherboard's South Bridge chip. PC/PCI using a Physical SB-LINK connection: The driver program (TBCDOS.exe) had very few options and was hardly documented. The wavetable daughterboard header is Windows only. It worked, doing the usual SB Pro emulation and software OPL-3 music. 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.
