SCSI Controller.....question about scanning devices at boot-up

[Trashman]

I hope someone can give me some insight on this.
I recently put together a new system, mobo is an Intel D850GB, my SCSI Controller is an Adaptec 2940U2W, HD is IBM Ultrastar 36LZX.

During boot-up, when the SCSI BIOS scans through scsi devices, a typical string would be:

SCSI ID:0 ...(followed by)model # of HD(which in my case is a U160 IBM)...data transfer rate(in my case) 80MB....then mode Ultra2/LVD.

I say a typical string, cause from my past systems, using same card thats been the norm.
Well, with this Intel board of mine it doesn't tell me that the drive is in Ultra2/LVD mode.
it lists:

SCSI ID:0.....model #.....data transfer rate 80MB

Thats where I'm at, I'm kinda stumped at this, I tried using another 68pin LVD cable, thinkin maybe the other was bad, but nope same thing.
If there is any more information I need to post just tell me.
Thanx guys,
Richard

If it shows 80 for the tranfer rate, it is Ultra2. My 29160 card shows what yours does - it doesn't state Ultra2 or Ultra160.

wonder if newer boards are setup this way or something.....my last 3 boards I had with this controller always told me that it was Ultra2/LVD mode, after the data transfer rate.....odd i guess....I mean I realize that 80MB is Ultra2 but that can be changed to 20MB in scsi bios, if ya wanted, thats just going by what I have set.... and when I have a device that I wanted to run in "SE" mode it would display that as well.
The way it is now, just not sure on the "mode" i'm in....confused i guess.

The newer cards and firmwares now show Throughputs to the drives now, It is easyer for the card to display (in short terms) also Some drive info such as mfg, type and connector type have been know to cause some confusions in the systems.
Im was using a 2940uw and a 3940uw some time back that used to give what you claim yours does, Im using a 29160 now that shows throughputs during posting now and I like it more that way since you actully know what its doing, It also doesnt confuse Windowz on how to use it persay buffering.
I have a old IBM 4.3gig Ultrawide that was rated on the 29/39-40's with only 40Mps which is normal but with the newer controllers Its showing 80Mps that would normaly be considdered UW2, I know it cant even get that close but Its nice to know that its alowed to.

Some names in devises could be counterfit, Flash a CD/R/RW with a bogus or modified firmware and the info read to the controller could claim its ultra160 or U2W and come to find out its only SE, The bus knows better by the connection it has.
