Description of problem:
I have Asus P4P800 motherboard with Intel 82801EB Ultra ATA Storage
Controller and it works in udma5 (ultra ATA 100) mode, but hdparm -i
/dev/hda shows that disk (Maxtor 80GB ultra ATA 133) works in udma2
mode. I tried to set hdparm -d 1 -X 69 /dev/hda (and also X69 and X67)
and none of this works. hdparm -t /dev/hda gives read speed about 30
MB/sek. Does this kernel support Intel 82801EB?

Version-Release number of selected component (if applicable):
kernel 2.4.22 2140 nptl smp

How reproducible:

Steps to Reproduce:
1. login as root
2.  hdparm -d 1 -X 69 /dev/hda
3. hdparm -i /dev/hda

Actual Results:  /dev/hda:
 setting using_dma to 1 (on)
 setting xfermode to 69 (UltraDMA mode5)
 HDIO_DRIVE_CMD(setxfermode) failed: Input/output error
 using_dma    =  1 (on)

you need a udma IDE cable to do it (80 pin)
