I'm using centos 5.2 with HDD as sata2. Sata2 doesn't set setting of dma. Board name I've got is gigabyte s-series(ga-ep45-ds3r). The reason to drive me crazy is to make hdd very slow while coping file. I've tried to put the command below.
hdparam -t /dev/hdc /dev/hdc: Timing buffered disk reads: 10 MB in 3.81 seconds = 2.63 MB/sec Speed of that is such sucks. After googling, I found the link below. http://www.centos.org/modules/newbb/viewtopic.php?topic_id=16149 As above link, I've read this... Em Quarta 31 Maio 2006 15:59, Mikkel L.

(It also says that DMA is off for /dev/sda.) So I've set the configuration at grup.conf like below. #boot=/dev/hdc default=0 timeout=5 hdc=noprobe << 추가 splashimage=(hd0,0)/grub/splash.xpm.gz hiddenmenu title CentOS (2.6.18-92.1.17.el5xen) But still dosen't work.
