- It is not as simple as adding something to the Adaptec, since this
- would not work for people using the other host adapters. I could add
- something to the upper level code.
-
- What I need to know is how does this device identify itself at boot
- time? Does it come up as a direct-access device? Does it come up at all?
- This is a scsi device, right? What is it that you cannot do until you send the
- special message? I guess what I am trying to say is that I can easily send the
- message, but I need to know which devices to send it to. Ideally this would be
- done dynamically based upon information that is determined by querying the
- various devices on the bus.
-
- I will send you my fax number once I figure out what it is :-).
