aic79xx driver problem

[nihaopaul]

one pointmaxtordo make a point saying is that their drives are scsi3 compliant and don't work with scsi2 commands well..
http://maxtor.custhelp.com/cgi-bin/maxtor.cfg/php/enduser/olh_adp.php?p_faqid=4

but they finaly gave a firmware update for the drive... just no explanation how too use it..also havn't tested yet as no information
plus a browse around the ftp site pointed to them giving me the incorrect path as my drives are atlas 10k iv (ftp://ftpdownload.maxtor.com/pub/Atlas%2010K%20IV/ and not the atlas-iv.

  Dear Paul Adams,

  Please forgive the previous technician. Here is the link to the firmware updates for this particular drive line. Please understand that updating the firmware constitutes a risk. If flashing goes wrong, it may render your hard drive unusable.
