after reading quickly this manpage and trying the following I still have
no luck on 7.0-RC FreeBSD.

Settings copied from the output of camcontrol inquiry da2 when using 6.2
(had it in my sent items, so easy to find).

Freebsd 6.2
da2: <SEAGATE ST336753LW HPS2> Fixed Direct Access SCSI-3 device
da2: 320.000MB/s transfers (160.000MHz DT, offset 63, 16 bit), Tagged
Queueing Enabled

Trying to get these parameters into camcontrol negotiate.

hulk# camcontrol negotiate da2 -a -R 160.000 -W 16 -v -T enable
Current Parameters:
(pass2:ahd0:0:4:0): sync parameter: 9

(pass2:ahd0:0:4:0): offset: 63
(pass2:ahd0:0:4:0): bus width: 16 bits
(pass2:ahd0:0:4:0): disconnection is enabled
(pass2:ahd0:0:4:0): tagged queueing is enabled
ahd0: SIM/HBA version: 1
ahd0: supports tag queue messages
ahd0: supports SDTR message
ahd0: supports 16 bit wide SCSI
ahd0: HBA engine count: 0
ahd0: maximum target: 15
ahd0: maximum LUN: 63
ahd0: highest path ID in subsystem: 0
ahd0: initiator ID: 7
ahd0: SIM vendor: FreeBSD
ahd0: HBA vendor: Adaptec
ahd0: bus ID: 0
ahd0: base transfer speed: 3.300MB/sec
Unit is ready
New Parameters:
(pass2:ahd0:0:4:0): sync parameter: 9
(pass2:ahd0:0:4:0): frequency: 80.000MHz
(pass2:ahd0:0:4:0): offset: 63
(pass2:ahd0:0:4:0): bus width: 16 bits
(pass2:ahd0:0:4:0): disconnection is enabled
(pass2:ahd0:0:4:0): tagged queueing is enabled

No luck.. :(
