Bus and ID # on ATA drives are largely imaginary, and only reported as such because the ATA card is pretending to be a SCSI controller to the Mac. ATA and SCSI drives are considerably different beasts, and cannot be on the same bus. If you have an ATA cable that is stamped CS or Cable Select, or seems to have a LOT of wires, it's a cable select cable. If it looks like an ordinary 50-line ribbon cable, the only reason it's working is because it's the only device on the bus. If you add another drive to that bus you will need to set the mastr and slave jumpers correctly.

It depends on what version of OSX you're installing. 10.0 and 10.1 will see that card as a scsi controller, and can be installed on any size partition. However, under 10.2 the card is correctly identified by the system as an ATA controller, and thus the 'first 8 gb' limit that applies to some iMacs and Beige G3's is in force, meaning that OSX must be installed in a partition smaller than 8gb and must be the first partition on the disk. (When formatting the drive's first partition, make it 7.98 gb in size) see:<http://docs.info.apple.com/article.html?artnum=106235> This isn't as limiting as you might think, since it's quite easy to move your Home folder to another partiton, and can also link folders on other partitons into the Applications folder, leaving the 8GB partition for just the OS.
