Hello !


I'm happy with two new wide Quantum Viking 7200 rpm drives and an ASUS
SC875 adapter. I have found ncrcontrol utility and tried it. 

ncrcontrol -i shows me:

T:L  Vendor   Device           Rev  Speed   Max Wide Tags
0:0  TOSHIBA  CD-ROM XM-6201TA 1030  10.0  20.0   8    -
5:0  QUANTUM  VIKING 4.5 WSE   880R  20.0  20.0  16    8
6:0  QUANTUM  VIKING 4.5 WSE   880R  20.0  20.0  16    8

but dmesg are different:

ncr0: <ncr 53c875 fast20 wide scsi> rev 0x03 int a irq 9 on pci0.9.0
ncr0: waiting for scsi devices to settle
scbus0 at ncr0 bus 0
scbus0 target 0 lun 0: <TOSHIBA CD-ROM XM-6201TA 1030> type 5 removable
SCSI 2
cd0 at scbus0 target 0 lun 0
cd0: CD-ROM
cd0: 10.0 MB/s (100 ns, offset 16)
can't get the size
scbus0 target 5 lun 0: <QUANTUM VIKING 4.5 WSE 880R> type 0 fixed SCSI 2
sd0 at scbus0 target 5 lun 0
sd0: Direct-Access
sd0: WIDE SCSI (16 bit)
sd0: 40.0 MB/s (50 ns, offset 16)
4345MB (8899737 512 byte sectors)

etc..

Why dmesg shows me 40 MB/s and ncrcontrol 20 MB/s ? SCSI BIOS boot message
shows me 40 MB/s for hard drives, too. Are there something incorrect ? Of
course I need the full capabilities of my new drives and adapter :)


Thanks
