I tried to get it to work with a late era P3, for the life of me the dos drivers would not allow legacy support to function with their driver, 16bit midi was fine sounded very clear.

Edit: I found a Old Vogons topic that describes the problem perfectly PCI sound cards and Chipsets from various manufacturers...

Not sure what you are asking, but I have a Yamaha 724 card in an AthlonXP machine, and running inside a Windows 98b dos box I get FM music and SB Pro sound effects.

I run it alongside an MX300 and used to get a lot of crashes due to both emulating SB Pro, but disabling one or the other fixes that [though I have a feeling I had to reinstall Windows along the way].

What I could not get to work was sound in DOS. My board has no SB-Link header either.

My 724 runs fine in DOS on my Tualatin rig. It was a pain in the ass to set up - I had to reserve irq 5 and DMA 1 in BIOS for Legacy ISA even if the card is PCI, but if I don't I can't get DOS SB compatibility. In windows the card runs on IRQ 7 and IRQ 5 for the Legacy device.

FM and SB Pro in Windows, FM in DOS.

The only thing I can't get working in dos is the XG synth.

Seems the only option for P4 MBs with Intel chipsets to work in real DOS is SB-Link, in case the boards had this uncommon connector.
Stays unclear still, how is with DOS box on P4 with i8xx in general. And what is with MBs on other chipsets for P4.

What is MB with your AthlonXP?

If the chipset has D-DMA, then it should work with proper settings (which you need to guess by stars and planets).

What MB is there? With SB-Link, I suppose.

Yes. Partly similar to AWE which has good GM support only inside Win9x.
I heard Quarantine had issue with SB-Link on YMF.

As I understand it's about 775i65G R3.0 and YMF744 from the signature. The MB has no SB-Link.
What sound drivers were used - vxd 1040 from Yamaha's site or other?

How many games refused to run correctly by this way?

Abit ST6 - so no SB-Link since it's an i815. It also works fine on my VIA KT333 boards. Both SB and midi. No XG tough.

Mine's an Asus A7M266. FM, SB Pro and XG/MIDI work in a 98 dos box. Nothing at all when I restart in DOS.

The bios lets me reserve IRQs and DMAs, and there is a UMB setting. Also you can allocate IRQs to PCI slots.

It doesn't especially matter to me that I can't get sound from this card in DOS.

Off topic: The MX300 has an SCB7 attached so I can flip between using SB Pro emulation on that, and SB Pro emulation on the YMF card. Quite quick to prove to myself that the FM Synth on the Aureal card is a bit thin sounding compared to the Yamaha, but not completely catastrophic.

Tested Doom 2 with both SFX & OPL3, and both worked. I ran SETUPDS /S, followed by DSDMA for both to work.

Board tested was a Socket 478 running a P4 3.4Ghz CPU, with an i875p Intel chipset made by BCM (BC875PLG). It has an ISA slot, so not concerned about compatibility without SB-link.

You need to reserve IRQ 5 and DMA 1 for LEGACY ISA. Do not allocate them to the PCI slots. It's the only way I got it to work w/o sb-link.

Frankly the only chipset I can't seem to get it to run on in DOS is nForce 3 and up. It sometimes acts up on nforce 2 chipset boards as well, but I don't need dos on those.

Interesting. I have data that D-DMA is not supported on i8xx. SB-Link was supported by i8xx chipsets, but MBs could to have no the connector.
So you are using 724F-V in real DOS (6.22 or 7 ?), not "DOS boot from Win9x", not 9x DOS box.
What is DOS driver's version - 3.14 or 3.16 ? Which is IRQ of PCI slot in which the card is intalled - #5 too ? DSDMA was not used befor games?
Will be good if you'll cite your ds.ini (under "code" tag) to understand what mode is used.

BC875PLG according to manual I've found has no SB-Link connector. Your card is 724F-V, other YMF chips would be good to test on i875 too sometimes. So another i8xx without SB-link connection which works in real DOS. DOS drivers seems to be 3.16.
Have you tested real-mode SFX+FM games, for example Dune 2, Flashback, ... ?
The cards settings are base220 irq5 dma1 ? You assigned in BIOS "Legacy ISA" for IRQ and DMA of you card ? IRQ of PCI slot is not same as which is assigned to the card ?
Cite, please, in code tags your ds.ini

Similar AMD-760 MPX has D-DMA. Probably yours too and with propper settings YMF will work by D-DMA.

In BIOS, I reserve IRQ 5 and DMA 1 as 'Legacy ISA'. The PCI IRQ assigned to the YMF724 card is different to the Legacy IRQ for Sound Blaster (SET BLASTER=A220 I5 D1 T4).

These tests were done in DOS 6.22 using the latest Yamaha DOS drivers. I don't have Win98SE installed to test in DOSBox at the moment, although this P4 board has full Win98 drivers.

From previous testing on 440BX chipset, I know this card isn't very compatible without SB-Link, so I haven't tested many games. I tried Dune II, and as expected, it doesn't run without SB-Link.

Regarding YMF744 & YMF754, I expect them to behave similarly without SB-Link in pure DOS. In Win98SE DOSBox, they should differ in compatibility from the YMF724 with various driver revisions (from previous tests on 440BX).

Thank you for information.
Without working real mode games using FM+SFX it's hard to say about acceptable pure DOS support. How other protected mode games behave is also unknown. Noticable is that you have "INTAIRQ=3" while BLASTER variable has irq5, so may be used kind of TSR emulation like on SB Live.

The Yamaha DS-XG cards are best used under win98. You also have the wonderful XG synth available under 98 for various games, even really old ones like Secret of Monkey Island witch works flawlessly under 98 on my K6 rig.

Not all games work in Win9x box.
If the percent of games which were able to work on your Tualatin in real DOS is significant, - the ds.ini and other settings used are interesting.

For GM in Win9x box should be better SB Live/Audigy as seems there were banks close to SC, which was used as etalon by developers. Also, on P4 it would not be much worse to use S-YXG, in case you'd prefer DB50XG-like sound somewhere.

Except Sound Blaster PCI cards (except those based on the ES1370) clock the DAC at 48khz and use badly implemented resampling for all 44.1khz PCM.

The only game I failed to make work is Duke3D - it will only run on the 724 if a SB-LINK interface is used (in DOS or windows). On my socket 7 machine it crashes when attempting to play digital samples.

It's not the only such game. But some of them maybe work in real DOS by D-DMA, DSDMA or something else.
