RE: PROMISE Ultra133 TX2 (PDC20269)

[Piszcz, Justin Michael]

Hrmm, I have never seen that syntax, have you tried

hdparm -X68 /dev/hde (udma 4)
Or
hdparm -X69 /dev/hde (udma 5)

What type of disk are you using?

root@p500:~# hdparm -X69 /dev/hde
/dev/hde:
 setting xfermode to 69 (UltraDMA mode5)
root@p500:~# hdparm -X68 /dev/hde
/dev/hde:
 setting xfermode to 68 (UltraDMA mode4)
root@p500:~# hdparm -X67 /dev/hde
/dev/hde:
 setting xfermode to 67 (UltraDMA mode3)
root@p500:~# hdparm -X69 /dev/hde

Hello,

I have the following problem with my controller:

I have attached a 8 GB UDMA4 Harddisk, but it works only with UDMA2. The
controller BIOS displays the right mode (4), but in the kernel dmesg it
comes with pio. after i execute hdparm -I /dev/hde it says:

... udma2* udma3 udma4

If I try to force the UDMA4 mode with hdparm -Xudma4 /dev/hde , ...
theres no difference. The harddisk leaves at udma2.

What can I do?
I have tried 2.4.26, 2.6.9, 2.6.10-rc1...

Can you help me?

Thanx, EnricoB
