I guess they don't support slow IDE because they didn't want to bother. PPC hardware has decent SCSI anyway.
and now we come to the real problem!
Yes, my blizzard has a decent scsi, but that is NOT supported by OS 4.x!!!!!
So, on BlizzPPCs only internal pio 0 IDE is able to boot OS4.x ..... and as for FastATA.. don't think there is drivers to enable faster speeds....
only Cyberstorms PPCs scsi is supported.
Thing is, that blizzard can have 256MB ram, Cyberstorm only 128...
Oh well.... you can't have it all!
