Sean,
It will do no good looking at the SCSI-2 standard which only defines up to
fast-10 speeds. You will find what you are looking for in the SPI-4 rev 2
standard. It has a definition of a mode page that will return the
information you are looking for. But don't expect to see it in products
that are shipping today as that feature is new in SPI-4 rev2.

Bye for now,
George Penokie

Does anyone have any idea how to obtain the bus type and bus speed from a
scsi device?  I have a U-160 drive connected to a Adaptec AHA2940 and I
need
to obtain the Bus speed and the bus type from the device.  Looking through
the SCSI-2 specs the inquiry data of a device doesn't contain this
information.  It appears that the information is obtained by the host
adapter at boot up time and there doesn't appear to be a way of obtaining
this information after boot.  Any help would be greatly appreciated.
