hdparm on FC7

[Jovan Spasojevic]

Hello,

sience FC7 i am not more able to set the (E)IDE 32-bit I/O support
and multiple sector I/O sience fedora 7
on Fedora 5 and 6 there was no problem i have write the comandos in 
rc.local (/sbin/hdparm -c3 -m16 /dev/hda) (now it /dev/sda) and works.
now on fc7 don't wokrs anymore all opts are marked as "off" only runs in 
UDMA 5 Mode. i have this options set because it have a better 
input/output Support/performance on my IDE/ATA100 HDD.

Why hdparm not works anymore. I think it is the new SATA Protocoll.

The Error that appears is:

[root@localhost jovan]# /sbin/hdparm -c3 -m16 /dev/sda

/dev/sda:
  setting 32-bit IO_support flag to 3
  HDIO_SET_32BIT failed: Invalid argument
  setting multcount to 16
  HDIO_SET_MULTCOUNT failed: Inappropriate ioctl for device
  HDIO_GET_MULTCOUNT failed: Inappropriate ioctl for device
  IO_support   =  0 (default 16-bit)


/dev/sdb:
  setting 32-bit IO_support flag to 3
  HDIO_SET_32BIT failed: Invalid argument
  setting multcount to 16
  HDIO_SET_MULTCOUNT failed: Inappropriate ioctl for device
  HDIO_GET_MULTCOUNT failed: Inappropriate ioctl for device
  IO_support   =  0 (default 16-bit)
[root@localhost jovan]#


This is the current output from hdparm:

/dev/sda:
  IO_support   =  0 (default 16-bit)

supports max ATA100???????????????

  * signifies the current active mode

But there is a error i have a Intel 775 Asrock Motherboard with ATA100 
and my Hardware support UDMA5 not UDMA6 (see above)
