AHCI on Southbridge SB600 - slow boot up in XP

J

Jerry

I am using winxp professional SP3 in my PC with the following configuration:
AMD 5000+ with 2G ram
Seagate 250G harddrive in my mobo ASUS M2A-VM HDMI bios 1501

I changed the setting in the southbridge from IDE to AHCI according to the
following link:
http://vip.asus.com/forum/view.aspx...id=1&model=M2A-VM+HDMI&page=1&SLanguage=en-us

Everything is ok and the performance is improved except winxp stops for
about 10 second when booting up which is same as described as the following
link:
http://www.tomshardware.com/forum/248043-30-sata2-problems-booting

I have tried different version of ahcix86.sys (driver for AHCI), but without
improvement for the above scenario. At present, the version of my ahcix86
is 2.5.1540.39

Anyone has encountered the problem and any solution to solve it?

Thanks in advance.

Jerry,

I have virtually the same system (same MB, Athlon X2 4800+, 320GB HD,
2GB RAM, WIN XP home) and recently I changed from IDE to AHCI. I too noticed
the same delay on boot-up, but don't think much of it since the overall
system speed has not been affected. I've been wondering why the disk
performance hasn't increased over IDE mode, since I have noticed little to no
increase in speed since I changed modes. I'm wondering if the core speed of
our processors (200 MHz, or is this system speed?) has anything to do with
it. If anyone can shine some light on this, I would appreciate it as well.

Thanks, Brian

I have checked the performance between in IDE and AHCI by the PC Wizard 2008
and HD Tune 2.55. The results in AHCI are even poor than that of IDE. In
the HD Tune 2.55, the seagate 250G even cannot properly display its disk
infos.

I have changed back to IDE mode already.

As I installed the windows in IDE mode, is there something need in the XP
professional that will add during installation? If yes, how?

I've have installed the same AHCI driver version (AMD RAID/AHCI Controller
Driver V2.5.1540.39, is the last updated version on Asus site).
I've an M3A Asus motherboard and I've notice a lack of performance during
WinXp boot and I've 2 MAXTOR SATA II disk (without RAID configuration). Why?
It seems better IDE instead AHCI mode (!!!!!).

It would help in diagnosing if you did some benchmark tests on the
drives/controller. AHCI isn't itself faster than standard SATA type
controllers - it provides hot swapping and native command queuing.
Unless you need those features it's best to set the controller to work
as Legacy type controllers.
Generally a recent SATA II drive should deliver an average speed
of 80+ Meg and an access time of 11-13 mSeconds.

One thing to check is the controller properties in Device Manager. While
SATA is a single Channel host, the properties still show as Primary and
Secondary with Auto detection. Toggle any unused channels to None.

Also many vendors ship SATA II tech drives with a micro-jumper that
limits them to SATA I performance levels - make sure the jumper has
been removed ( if installed ).

thank for this suggestion, unfortunately I didn't found these parameters. In
Device Manager (hw configuration) under 'Controller SCSI and RAID' I've only
'ATI AHCI compatible RAID controller' and 'ATI RAID Console'. In the
properties folder I see only: General, Driver, Details and Resources, but I
don find your suggested parameter.
Could you explain in deep where I have to check?

I've already checked and I've removed the SATA I limitation jumper before
the installation.

thank you for patience
