Darthnvader's technique of loading fcode drivers from disk probably works for sata cards too, so you could test a driver without flashing if you cared to.

Judging by their respective datasheets, the  sil3112 and the sil3124 seem to have totally different architectures and internal registers. I personally wouldn't try to crossload firmware from them. If SATA II is very different from ATA, then I think it very unlikely that any existing ATA Interface Modules work with the sil3124. I lack the relevent knowledge to tell, but it at least seems that way from the wikipedia entries on SATA and ATA.

high possibility of YES i would say
based on the SIL3112 track record anyway

the firmtek 1s2 firmware was a special case scenario because of it being written to incorporate its advanced "Copy protection" technique -- but if firmware exists for the Sil3112 i dont see why a talented programmer who knew what he was doing couldnt duplicate the bootability for another chipset (sil3124) and even create multiple different size ROM's (that would be able to flash to other sil3124 cards that have soldered flashrom chips instead of socketed) and to include or not include the injected OS9 / OSX Kernel extensions that are embedded within the firmware. or make seperate firmwares (to lower the size) for os9 seperate + osx seperate rather then have them combined into one "catch-all" product the way firmtek did.

re: writing a driver;
im fairly certain a sil3124 card right now; if any of us had one; would "work" when booted in os9... as a data drive but not a boot drive; if you tried to boot from it i dont think it would find the tbxi toolbox image + boot; but who knows! there might even be a way to use the openfirmware environment to force a boot from the card in similar fashion to how people were ablet o force usb2 drive booting; without even editing firmware or re-flashing.

i havent confirmed that the sil3124 function as data drives in os9 without any "driver" or special "Re-flashing" but i would love it if someone else could test + report back on their findings; if noone else does id liek to get my hands on some of these cards to test  while they are for sale for 10$ on ebay; i have a strong suspiscion the reason that the sil3112 supply has dissappeared was because of "Harrymatic" posting on macrumours site about flashing the weibetech firmware.. which requierd no re-soldering or re-chipping which the end result was a sil3112 card that boots in osx, not os9; anyway the sil3112 cards seem to be SOLD OUT  so there needs to be a new solution located. theres people trying to sell tempo sata sil3112 that is compatible on the QS in os9 for 400$ on ebay right now

i messaged him but i think my msg is in his spam folder on fb (thanks facebook)
ill hopefully talk to him sometime this weekend

he has multiple solutions for doing this; hes pro level leet hacker guy vintage PC collector
i think he has the apple II version of the Central point; along with another competign product and various  other methods of achievign the same result

macStuff: fantastic! i've send you a PM.

its not a nightmare to get working at all if u have the right installer 100% complete for the right mac.
this is the part where i'm having nightmares... since i'm trying to find a copy that runs on a particular mac, my options are a bit limited.

i just read that thread you linked, it's pretty lucky you know a guy with one of those copy ii pc cards!
i did a bit of research on the subject of flux level disk copiers, but it seems none of them support mac hfs disks(kryoflux, fluxengine etc)

how many floppies do you need? how many would be possible without inconveniencing your friend too much?

Interesting that it just seemed to need some more time to figure itself out after a long stint on the shelf

my beige G3 is like that. i think its just old electronics, really. if it gets unplugged for more than a few hours, I have to let it sit, plugged in for a while, before it will start up. not sure why, its got a new lithium battery in it.

my korg oasys pci card in another machine is like that too, but its only the card.

Thanks, I know the limits of the DV format.  I guess I was asking if one version of QT has cleaner output during this period.. but understand, garbage in...

One thing I noticed is iMovie always did a good job identifying the camera and tape transport, FCP saw a camera and ignored transport controls, I had to start import with menus.  Maybe bad install on my part.

Edit:  Just found a few post saying FCP likes a time code?  Not on my rusty oldest tapes...

Will all of the cards that use a chipset function identically?

If someone were to write a driver for one particular card that uses sil3124, would it be likely that other cards will also work?

thanks for adding that info;
honestly i think theres a much larger pay off in getting something liek thsi working rather then trying to invent a 9.3
i just dont get the fascination with trying to invent a new version of the os that never was;
when theres much more realistic goals that could be set; and achieved with massively better outcome for all;

i know from first hand experience its very easy to achieve speeds above 188MB/s with these longer PCI-X cards because of their 64-bit /33mhz operation; the Acard 6885M card that i have is the fastest card i have and its based on ATA133 simply because of the 64bit/33mhz bandwidth it offers above and beyond the normal 32-bit/33mhz cards; the sil3124 cards are available in great number under 10$ in the usa; WITH SOCKETED FLASH CHIPS usually of the 040 variety from what i could see; this is a huge oppourtunity if people can wake up and smell the coffee;

To have an ATA chipset usable by Mac OS, it will need to have an ATA Interface Module written for it.

To have it be bootable, it will also need a Fcode ROM to make it be usable by Open Firmware.

Here's some documentation on Apple's ATA implementation (including how to write AIMs): http://mirror.informatimago.com/next/developer.apple.com/documentation/Hardware/DeviceManagers/ata/ata.html

Quite a few documents are relevent to Open Firmware:

"Designing PCI Cards and Drivers for Power Macintosh Computers" is probably needed for both AIMs and Fcode. http://mirror.informatimago.com/next/developer.apple.com/documentation/Hardware/DeviceManagers/pci_srvcs/pci_cards_drivers/Designing_PCI_Cards_Drivers.pdf

And here is the datasheet on the SIL3124: http://www.alldatasheet.com/datasheet-pdf/pdf/218215/SILICONIMAGE/SII3124ACBHU.html.

The SIL3124 datasheet helpfully describes how to access the flash chip from PCI. Apple's PCI Driver Development Kit may be useful for that: https://www.staticky.com/mirrors/ftp.apple.com/developer/Development_Kits/PCI_DDK_3.0.sit.hqx.

Developing drivers for this seems doable. It just needs dedication from a good programmer. I suppose that may be hard to come across. I don't know the exact number of hackers working on the 9.2.2 reversing project, but I am pretty sure it is less than 10.
