Centos 5 on Intel P35 based ASUS Motherboard

Few months ago I decide to buy a new computer for our hosting services that planned to be colocated at Jakarta (directly connected with IIX – Indonesian Internet eXchange). The specs was great (Q6600 – Intel QuadCore, with 4Gb of RAM, and P5KC Asus Motherboard). Sadly my favourite CentOS cannot be installed smoothly. But thank god now server is up and running with CentOS 5 and CPANEL installed – ready to roar!!!

Here’s some problem before :

1. DVD-ROM was detected, but no SATA Disk detected
   Solution : put acpi=off on /etc/grub.conf, but problem no. 2 comes up
2. Installation went through smoothly, but SATA disks are detected as IDE
   So I got a very poor disks performance. Usualy when I perform “hdparm -Tt /dev/sdX” on SATA disks, Timing buffered disk reads will hit 60 – 70MB/sec. But on my new machine, it shows only 4MB/sec. And it’s not detected as sdX, but hdX
3. Attansic onboard ethernet is not detected
   But it’s quite easy to solve this problem. Just put Centos compatible ethernet, or download attansic ethernet driver for linux. I do both of it (hey .. we need backup right?)

What I most concerned is problem No#2. Get real!! 4MB/sec?
