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)

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