Hello,

Is it normal to have pdc202xx driver to enable only UDMA33 on Ultra133
TX2 (PDC20269)? Disk is new 60GB Seagate Barracuda. U133TX2's BIOS says
it has enabled UDMA5.

Driver is: ide-2.4.19-p7.all.convert.10.patch.bz2

Here's some info from dmesg:

PDC20269: chipset revision 2
PDC20269: not 100%% native mode: will probe irqs later
    ide2: BM-DMA at 0x5800-0x5807, BIOS settings: hde:pio, hdf:pio
    ide3: BM-DMA at 0x5808-0x580f, BIOS settings: hdg:pio, hdh:pio

hde: ST360021A, ATA DISK drive

hde: host protected area =3D> 1
hde: 117231408 sectors (60022 MB) w/2048KiB Cache, CHS=3D116301/16/63,
UDMA(33)


/proc/pci/ide/pdc202xx says only (nothing else):

                                PDC20269 TX2 Chipset.

And from "lspci -vvvxxx":
