I have a ASUS board with the 915G Intel chipset. I have OSX and Windows XP installed on a SATA drive and it works great using the Darwin bootloader. I also have a secondary hard drive installed that is on IDE. I can't get OSX to recognize the IDE hard drive. Windows sees the drive without a problem. Can anyone help me get OSX to recognize the drive?

Apple should see your IDE hard drive, try flashing your motherboard to the latest bios.

I just got it to work. For some reason, it will only recognize the drive if it is on the primary IDE controller. I had it hooked up to the secondary controler. So....this leads me to believe that OSX can't see the secondary IDE controller. Any idea on how to fix that?

Same problem here (AMD64 3200+ Venice, ASRock K8-Combo-Z). Couldn't even install (10.4.1) until I put both the DVD drive and the HDD I was installing to on the primary cable (still waiting for root device).

Sure enough, after installation, my DVD drive (now back on the secondary port) is not detected. Haven't tried putting it back on the primary controller yet. Will try 10.4.3 shortly. Hopefully I'll have more luck with that

Edit: Now running 10.4.3 (8F1111A), and no better luck with the IDE interface. Having read the wiki a little more thoroughly, ULi chipsets, which my MB uses, seems like a no go. Might have a look into bastardising a driver to work with it. Not familiar with IOKit though, so it may take some time

On some sets Mac OS can't see the secondary channel if the primarye isn't full populated (Master and Slave drives) on primary. On some chipset even with full populated primary channel.
