When I boot FreeBSD 2.2.1 on a Dell PowerEdge 2100, a strange message
appears when the ahc driver initializes the SCSI devices:

..............
ahc0 <Adaptec aic7880 Ultra SCSI host adapter> rev 0 int a irq 14 on
pci0:18
ahc0: aic7880 Wide Channel, SCSI Id=7, 16/255 SCBs
ahc0 waiting for scsi devices to settle
ahc0: target 0 Tagged Queuing Device
(ahc0:0:0): "SEAGATE ST32171W 0484" type 0 fixed SCSI 2
sd0(ahc0:0:0): Direct-Access 2047MB (4194057 512 byte sectors)
ahc0:A:5: refuses WIDE negotiation.  Using 8bit transfers
(ahc0:5:0): "NEC CD-ROM DRIVE:462 1.14" type 5 removable SCSI 2
cd0(ahc0:5:0): CD-ROM can't get the size
...............

This computer has an on-board Adaptec 7880 Ultra-Wide SCSI controller,
a Seagate Barracuda 4LP HD (Ultra Wide, target 0), and a NEC CD-ROM
(SCSI-2, target 5). The message I cannot understand is:

	ahc0:A:5: refuses WIDE negotiation.  Using 8bit transfers

ahc0:A:5 ??? Target "A" (10 decimal, I guess)???? There isn't any
device configured as target 10. I'm afraid that the ahc driver doesn't
recognize properly the HD, and that it does 8-bit transfer instead of
16-bit. I don't know if there is any easy way of getting info
from the ahc driver about the parameters it's using for communicating
with the HD.

Any ideas?

Thanks,
