Wooow Bernie, reading that made my eyes go
But this is the most important part for me i guess:
QUOTE
* EIDE. Enhanced IDE is the Western Digital marketing standard that is often considered an official standard, but isn't. It incorporates ATA-2 speeds, ATAPI and calls for _two_ IDE buses, each of which supports a master/slave combination. It's popular, but it's not a standard. EIDE is specifically supported on the original Power Macintosh G3 series, although EIDE drives are generally backward compatible and can be used in most earlier Mac models.
So, as Kelly also mentioned, E-IDE is backwards compatible, so i can be sure of that.
Thanks people
