I intend to replace fading SCSI drive by a SATA one. The motherboard is PCI and no SATA controller on board. So I need a SATA/PCI controller.
Is there something wrong to do this kind of switch? Some told me that I won't be able to boot that drive. Loosing part of the SATA interface speed is not a decisive factor on this machine Is there are some prefered Linux SATA controller?
Need experienced feedbacks.

This is *not* a CentOS specific question. But some of us have been there.
I'm going to urge you to, instead of replacing anything, backup your SCSI drive to an external or separate NFS repository,and do a clean rebuild on a new SATA drive. The Adaptec 2140 series of controllers are pretty good and pretty well Linux supported, and pretty cheap.
If that's not feasible, talk to us. It'll take some fascinating configuration changes to mirror things, but gods know I've done that.

oldschool desktop 32bit 33Mhz parallel PCI will be a performance bottleneck for more than 1 SATA drive.
Is your server PCI 32bit, PCI 64bit, or PCI-X (64bit, 100-133Mhz), or is it PCI-Express and if so does it have x4 or faster slots?
As someone else said, a SATA card likely will NOT be bootable, unless it has a boot eeprom on it, and these cost more.

The mother board is an MSI KT# MS6380E with an AMD2100XP cpu FSB is 166 mhz; chipset is 333mhz

On good point I have to care, Many thanks

thats some old stuff. :-/
32bit 33Mhz PCI slots, with an AGP slot for the video card. no server grade cards will work at all, and a simple PCI SATA card will be bottlenecked if more than 1 drive is actively transferring at once
