How to Linux find a SATA Harddrive

I had problems to install Linux in a new machine with Dual-core processor, 2 GB of RAM and 160GB SATA Drive.

I was using CentOS 5.0 Linux (RedHat 5 Entrerprise like), and installer couldn't find my SATA DISK.

If you have the same problem, the following describe how i made the install works

Forcing Linux installer to find SATA disk

In installer boot prompt put this command

boot> linux all-generic-ide

Making the Linux kernel find SATA disk throw GRUB boot loader

After install of my linux, the first boot crash the system, so i not think twice. Boot the system again and in GRUB prompt, edited the current entry with e command and added the all-generic-ide in line:

 module /vmlinuz-2.6.18-8.el5xen ro root=LABEL=/ rhgb quiet all-generic-ide

e with b command, boot the system without problems.

Made this change in GRUB forever

Edit the file /etc/grub.conf and add this option all-generic-ide like the following example.

# grub.conf generated by anaconda
#
# Note that you do not have to rerun grub after making changes to this file
# NOTICE:  You have a /boot partition.  This means that
#          all kernel and initrd paths are relative to /boot/, eg.
#          root (hd0,0)
#          kernel /vmlinuz-version ro root=/dev/hda2
#          initrd /initrd-version.img
#boot=/dev/hda
default=0
timeout=5
splashimage=(hd0,0)/grub/splash.xpm.gz
hiddenmenu
title CentOS (2.6.18-8.el5xen)
        root (hd0,0)
        kernel /xen.gz-2.6.18-8.el5
        module /vmlinuz-2.6.18-8.el5xen ro root=LABEL=/ rhgb quiet all-generic-ide
        module /initrd-2.6.18-8.el5xen.img
title CentOS-base (2.6.18-8.el5)
        root (hd0,0)
        kernel /vmlinuz-2.6.18-8.el5 ro root=LABEL=/ rhgb quiet all-generic-ide
        initrd /initrd-2.6.18-8.el5.img

If the problem persist

In my researchs, i found the folling options:

 >> linux all-generic-ide irqpoll pci=nommconf

To me the all-generic-ide works fine, so i not test the others, maybe to you this options works.
