So how is two channel and four larger than 4GB accomplished with newer OS than 3.1 without using IDEFix?

The ATAPIismajik ROM module?

Patches how? It replaces scsi.device?

To use the secondary port on ROM 2.0, 3.0 or 3.1, the IDEFIX software package should be installed.
 
Large hard drives with capacity over 4GB supported on OS 3.5, 3.9 and 4.1.

In the light of OS 3.1.4 and upcoming 3.2, this opens a few questions...

* If IDEFix97 is required for two channels only for 2.0-3.1 kickstarts, then it is also likely that using the ATAPIismajik kickstart module with scsi.device from OS 3.5 onwards also works - can this be confirmed?

* That large hard drives are supported only on the OS releases that has scsi.device wich supports large drives (and even OS 4.1) suggests that scsi.device of OS is used, and that “the patch” just does the same as ATAPIismajik does - enables the two channel support in the OS scsi.device - can this be confirmed?

* Why isn’t compatibility with OS 3.1.4/3.2 mentioned at all?

Unlike some hobbyist IDE adapters, this advanced, modern design inhibits read errors and false IRQ's.

Hostile marketing? Do you have anything to back up these claims? Or is this a weird way to describe that your adapter has cache and hence “buffers away” the IRQs and “temporary bad sectors” that drives can emit on cache flush when using unbuffered PIO and a crappy ata drivers that doesn’t handle it well? I ask because I have never had such issues with “hobbyist IDE adapters”, only problems I’ve seen have been with other “professional” adapters, like ELBOX FastATA, when pushing the speed limits using their “professional drivers” that does who-knows-what. The hobbyist adapters all worked just fine at regular speeds. Is your solution here another one that does “who-knows-what”, or is there proper documentation on this hardware and its software?

Instead of telling me to chill, why not answer the questions?

What are you doing to scsi.device to make two channels appear? Replace it? Patch it? Use the ATAPIismajik ROM module? Or do I need to buy it to find out?
