View source for 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.
