UDMA(66) drive coming up as UDMA(33)?

["David St.Clair" <dstclair@cs.wcu.edu>]

I'm trying to get my hard drive to use UDMA/66.  I'm thinking the cable
is not being detected.  When the HPT366 bios is set to UDMA 4; using
hdparm -t, I get a transfer rate of 19.51 MB/s. When the HPT366 bios is
set to PIO 4 the transfer rate is the same. Is this normal for a UDMA/66
drive? What makes me think something is wrong is that the log says

"ide2: BM-DMA at 0xbc00-0xbc07, BIOS settings: hde:pio" <-- PIO? 

and

"hde: 27067824 sectors (13859 MB) w/371KiB Cache, CHS=26853/16/63,
UDMA(33)" <--- UDMA(33)? shouldn't it be UDMA(66)?

Any ideas what might be wrong? Possible bug?
