OMGOSH this hurts me! As I was definitely looking forward to hook an ultra fast (UDMA7) SanDisk CF card to the Promise ATA 100 !!!
Weird, for what I know, differently from IDE to SD Cards converters, the IDE to CF adapters do not need any electronic control processors as the CF cards are actually IDE devices. The adapters just adapt the IDE connector to the CF card connector. Why wouldn't they work with the Promise card?
Compact Flash card manufacturers did not always implement DMA modes properly (and in some cases, not at all), nor are they compatible with some of the tight timing parameters used by some controller cards.
So far I've had great results with Sandisk cards, but Lexar Professional cards has been very problematic on anything but the Sil3112.
When I say slow as ballz, I'm talking transfer rates in DOS of maybe ~4-6MB/s read.
For a 486, this is plenty fast. For an AMD k6-III at 500Mhz running Windows 98... not so much.
In your case, the Sil3112 is worth trying. The card is cheap as chips (as Phil would say), and very tolerant of different BUS speeds and a wide range of CF cards.
I use it as my fallback card. It always works.
