Unfortunately it's in MS Word 6.0 format (some little-known machine specific format, I understand), but the text seems interesting! Actually it seems to have some useful info within: ATA Anonymous FTP Site fission.dt.wdc.com ATAPI directory is: "/pub/ata" (now I think about it I've got a feeling that I couldn't get onto fission, but I think it was on one of the other WD machines. Perhaps I found a copy later on seagate?). Hope this helps, Stuart. -- Stuart Tyrrell Stuart@stdevel.demon.co.uk Stuart Tyrrell Developments Hardware/Software design & support PO Box 183, OLDHAM.
