>Description:

On NetBSD/i386 at boot time I normally see wd* report what PIO/DMA/UDMA
mode it is using to access the disk.  For example:

sanctum $ grep ^wd0 /var/run/dmesg.boot
wd0 at atabus0 drive 0: <WDC WD400BB-00CAA1>
wd0: drive supports 16-sector PIO transfers, LBA addressing
wd0: 38166 MB, 77545 cyl, 16 head, 63 sec, 512 bytes/sect x 78165360 sectors
wd0: 32-bit data port
wd0: drive supports PIO mode 4, DMA mode 2, Ultra-DMA mode 5 (Ultra/100)
wd0(piixide0:0:0): using PIO mode 4, Ultra-DMA mode 5 (Ultra/100) (using DMA data transfers)


On NetBSD/hpcmips this line is missing from the boot messagese:

moby $ grep ^wd0 /var/run/dmesg.boot
wd0 at atabus0 drive 0: <SAMSUNG CF/ATA>
wd0: drive supports 1-sector PIO transfers, LBA addressing
wd0: 2000 MB, 4065 cyl, 16 head, 63 sec, 512 bytes/sect x 4097520 sectors

Is this a bug in wd?  How can I determine what PIO mode is being used here?
