SFF stands for "Small Form Factor", as in the "SFF Committee Information Specification for Bus Master Programming Interface for IDE ATA Controllers Rev 1.0" from May 16, 1994. That document is basically a committee rubber-stamp of the earlier Intel "PCI IDE Controller Specification Revision 1.0" dated 3/4/94. Would anyone like copies ? Cheers
