Are there any socket 370 motherboards with the intel 815 chipset that have isa and support tualatin cpu's

See Re: Is there any Tualatin-compatible Socket 370 board that doesn't cost a million dollars?

i815 doesn't have native ISA support. The few i815 chipsetted boards with ISA slot make use of a bridge chip which supposedly has varying compatibility with any ISA card that requires DMA iirc.
If you want s370, proper ISA support and Tualatin support, you're probably gonna end up with VIA (seems to be the most common non-Intel s370 chipset around) and even then some of those boards don't come with an AGP slot.

You can have a look in this chart https://www.vogonswiki.com/index.php/List_of_ … 70_motherboards

VIA is likely easier and a safer bet, but you will likely only find Tualatin capable boards with a single ISA slot. If you need more ISA slots on a Tualatin capable board, you will probably need to hunt down an industrial board that does work with ISA DMA and likely 815/ICH2 based with a third party PCI-ISA bridge. They do exist (I own and use one), but the degree of ISA DMA capability (if any) will vary, as Tetrium mentioned. Additionally, you will likely need to either rely on the experiences of board owners on Vogons to know if ISA DMA works or trial and error as this info is rarely publicized by board manufacturers/vendors (industrial applications do not usually seem to require ISA DMA, so usually not considered a worthy selling point, AFAIK) .

Also, keep in mind that the list shared by Tetrium is a great starting point but is in not exhaustive (even says so at the top of the page 😉 ). For example my Ipox industrial board is not listed .

I love my Ipox IP-3ETI23

Pluses :
- 3 ISA slots with DMA support (ITE8888 PCI ISA bridge)
- Tualatin support
- onboard Ethernet

Minuses :
- ISA DMA does not work with Interwave (GUS PnP, etc) cards, but works fine with everything else that I have tried, including GF1 (classic GUS), SB16/AWE32/AWE64, CS4237 (Orpheus), YMF715E (Audiotrix 3D/XG) and Opti 929 (Turtle Beach Monte Carlo rev. 2)
- Does not have working NMI support as far as AWE32/AWE64 DOS MPU-401 to EMU8000 re-direction is concerned (aweutil /EM does not work). Re-direction works fine for DOS applications running under Windows 98SE . I do not recall if I have tried MegaEM or SBOS, but I doubt they would work either due to the same NMI issue .

Unfortunately, these boards are not easy to find these days .
