Ok, I'd also do the following:
On the "Change..." view, change Mask from 0x7fffffff to 0x7ffffffe and change MaxTransfer from 0x1ffff to 0x1fe00.
Also I wouldn't first install the OS on an FFS partition and then change it to SFS, I'd create SFS partitions at once. Create an emergency disk, copy pci.library to it, then boot from it. If it works, copy SmartFileSystem to it. Now use HDToolbox to partition your drive. You may also want to copy the latest HDToolbox (that from Boingbag2) to a floppy disk, so you don't have to fiddle around with the Heads/Sectors/Cylinders values by hand. (I think there is not enough space on the emergency disk for HDToolbox, so it has to be a seperate disk).
Oh, if your HDD is connected to the FastATA, you also need fastata.driver and fastataprefs in order to deactivate the split mode.
Bye,
