[ cross-post to "scsi" and FU2 "scsi" ]

According to Vallo Kallaste:

Hmmm, mine is 4.08.00 and I have the 4.09.00 upgrade. Time to check on ASUS 
and/or Symbios for a new upgrade (although having no problem makes me vary
of updating it).

Funny. My IBM drives report an offset of 15 with the ASUS and my new
VikingII reports 8 on the built-in 7880 UW board...

[ASUS SC-875]
da0 at ncr0 bus 0 target 0 lun 0
da0: <IBM DCAS-34330W S65A> Fixed Direct Access SCSI2 device 
da0: 40.0MB/s transfers (20.0MHz, offset 15, 16bit), Tagged Queueing Enabled
da0: 4134MB (8467200 512 byte sectors: 255H 63S/T 527C)

[Adaptec 7880/UW]
da0 at ahc0 bus 0 target 6 lun 0
da0: <QUANTUM VIKING II 4.5WLS 4110> Fixed Direct Access SCSI2 device 
da0: 40.0MB/s transfers (20.0MHz, offset 8, 16bit), Tagged Queueing Enabled
da0: 4350MB (8910423 512 byte sectors: 255H 63S/T 554C)

What is the exact meaning of "offset" ?

And what is the difference between the 4.5WSE and the 4.5WLS model of
VikingII (I don't have the complete manual) ?
