I hate to somewhat necro an thread but in effort to put some misinformation aside about this particular pci sound chipset. Revolter pretty much answered the main topic about phil's old video and how the card will work on those chipsets.
but here is some more info on the ess-solo1 and it's general compatibility.
First, ESS made the solo-1 compatible with chipsets that support SB-LINK or Distributed DMA (DDMA) and later revisions like the allegro and maestro cards retain this compatibility aside from having an hardware FM synthesizer like solo-1 did.
Second, All of the ESS pci cards have an fall backup legacy mode which uses an DMA Controller snooping mechanism which uses the pci bus to gain access. Using pci memory writes, it captures all SB DMA and directs to the Solo-1 without needing to require the computer's onboard DMAC doing DMA transfer job.
This snooping mechanism is known as Transparent DMA which is based on a hardware level and not a software solution like what creative did with the SBLIVE cards.
This tech does not use a TSR so this makes one of the few cards which can work in real mode dos without needing to rely on system memory or protected mode to perform SB functions in software. Although the ESS dos drivers like "ESSAUDIO.SYS/SOLO.SYS" are included to reroute PCI interrupt acknowledge "INTA IRQ" to desirable irqs "aka irq 5, 7 or 9" for the Sound blaster layer to function properly because the ESS audio codec need to be on the same pci irq number as the Sound blaster Mode.
T-DMA is NOT TO BE CONFUSED WITH WRITE BACK DMA (WBDMA) as this was an common technique used in a lot of pci sound cards as an legacy fall back which the ESS family can also use. (This is known as snooping the DMAC and writing back to the DMAC which was unreliable on most sound chips)
T-DMA only works reliably on pci chipsets with compatible PCI to ISA Bridges and DMA Controllers / LPC buses which allow access to the ISA DMA Controller, which explains why most later intel and non intel chipsets either don't work or work unreliable cause the ISA DMA in some lpc aren't supported. See more info about LPC supporting ISA DMA and chipsets with DMAC that works with compatible LPC: ISA slot motherboards from AliExpress
VIA Chipsets work well cause they all have an native ISA bus and later chipsets like VIA VT8233 to VT8237R use external LPC buses which still have access to the DMAC inside the mentioned southbridges.
Oh did i mentioned that the LPC Bus works with conjunction with the PCI Bus, Thats because they work with the same specification other than that LPC is suppose to be a substitute for the ISA bus.
As a final note for reference after writing this needless long essay about this sound card; I REPEAT. THIS SOUND CARD DOES NOT NEED AN TSR PROGRAM TO ACTUALLY FUNCTION IN REAL MODE DOS.
This aside, All of this info is available on the wayback archive on ESS Tech's patents and technologies which i assume is expired i think so yeah...
Edit; It is known that some LPC bridge chips can act as an DMA controller for super I/O transactions like a parallel port or floppy controller but it's not fully confirmed if this is needed for legacy functions towards PCI devices that requires a real ISA DMAC .
