Fedora 10 with megaraid controller

This controller is found in some older Dell servers.

Install Fedora 10.
Boot of the first install CD in rescue mode and chroot /mnt/sysimage.
cd /boot
mv initrd- initrd-
mkinitrd –with=scsi_wait_scan initrd-
exit # to reboot
This worked fine for me on a Dell1600 with Perc controller. In troubleshooting this, I found some posts saying that the module is call scsi_wait-scan. This is incorrect. Scsi_wait_scan worked fine for me.

Fedora Hard Drive install from ISO image.

If you want install Fedora 10 from the DVD ISO image download to a hard drive, you need to extract the images/install.img into the same directory.

Assume the Fedora-10-i386-DVD.iso file has been downloaded to /download.
cd /download
mount -t iso9600 -o loop Fedora-10-i386-DVD.iso /mnt
mkdir images
cp /mnt/images/install.img images
cp /mnt/isolinux/initrd.img /boot
cp /mnt/isolinux/vmlinuz /boot
vi /etc/grub.conf

title Fedora 10 Upgrade
root (hd0,0)
kernel /vmlinuz ro
initrd /initrd.img

Make sure you note device name for the partition of the /download directory.
Boot up the “Fedora 10 Upgrade”.
Choose Hard drive install.
Choose the correct partition device noted above, and the directory where the iso has been downloaded.

Fedora 10/Ubuntu Intrepid Trackpad configuration

Create the following file /etc/hal/fdi/policy/appletouch.fdi. This is the best place to make configuration in this version of linux. /etc/X11/xorg.conf is no longer the best place.

Put the following in the file:

How to access MacOSX boot partions.

To force a MacBook Pro to boot a CD, hold down the C key while rebooting.
To view all the boot options available on a MacBook Pro, hold down the “option” key while rebooting.

Dual boot MacOSX and Fedora 10.

This was on a MacBook Pro (Powerbook G4 – Early 2008 model) running Leopard.

I went through the bootcamp procedure, and chose to install Windows.
I carved out 50GB of the 200GB drive.
Installed Fedora 10 on that partition.
I installed the boot loader on the partition, NOT the MBR.
I found that it would always boot up Fedora at that point.
I thought that I had messed up the boot record at that point, so I tried to boot of the CD.
That was when I discovered the “Hold down C at boot to force boot off CD.”
I did a repair on my MacOSX partition. All checked out fine, as I had expected.
Then, I discovered the “Hold down the “option” key at boot to view all your boot options.
There they were “MacOSX” and “Windows”.

I am currently using this to boot the different operating systems.
