I'm using Redhat 9.0 on A7N8X Deluxe with MaxtorDiamondPlus 9 120 Gb SATA
HD, the only way to obtain more disk performance is to run before install
"hdparm -d1 -Xudma2 /tmp/hde" and after create in /etc/sysconfig the
harddiskhde file with
DMA = 1 and EXTRA PARAMETER = -Xudma2.

Using hdparm -t /dev/hde HD speed increase from 1.3 MB/sec to 50.50 Mb/sec.
installation go faster and PC are really usable.

It's the better way to tune HD performance or someone know a better once ?

When linux boot siI3112A controller fail DMA test and set SATA controller in
pio mode, this is the reason for very poor performance.

Please write your experience.

Thanks in advance.
