Most certainly not... this message is typed and will be sent out from
a Shark running 4.0.1, with this disk:

wd0 at atabus0 drive 0: <SAMSUNG HM060HC>
wd0: drive supports 16-sector PIO transfers, LBA48 addressing
wd0: 57241 MB, 116301 cyl, 16 head, 63 sec, 512 bytes/sect x 117231408 sectors
wd0: drive supports PIO mode 4, DMA mode 2, Ultra-DMA mode 5 (Ultra/100)
boot device: wd0
root on wd0a dumps on wd0b
root file system type: ffs

(how again does one find out what mode the driver actually uses to access
the disk?)

Regards,
        -is
