290 Part III . Choosing and Installing a Linux Distribution The swap partition is often set to twice the size of the amount of RAM on your computer (for example, for 128MB RAM you could use 256MB of swap). Linux uses swap space when active processes have filled up your system s RAM. At that point, an inactive process is moved to swap space. You get a performance hit when the inactive process is moved to swap and another hit when that process restarts (moves back to RAM). For example, you might notice a delay on a busy system when you reopen a window that has been minimized for a long time. When RAM and swap fill up, no other processes can start until something closes. Bottom line: Add RAM to get better performance; add swap space if processes are failing to start. Red Hat suggests a minimum of 32MB and maximum of 2GB of swap space. Click the Next button (and select OK to accept any changes) to continue. 13. Configure boot loader. All bootable partitions and default boot loader options are displayed. By default, the install process uses the GRUB boot loader, installs the boot loader in the master boot record of the computer, and chooses Fedora as your default operating system to boot. If you keep the GRUB boot loader, you have the option of adding a GRUB password. The password protects your system from having potentially dangerous options sent to the kernel by someone without that password. This does not have to be the same password you use to log in later. (The GRUB boot loader is described in Chapter 7.) The names shown for each bootable partition will appear on the boot loader screen when the system starts. Change a partition name by clicking it and selecting Edit. To change the location of the boot loader, click Configure Advanced Boot Loader Options, and continue to the next step. If you do not want to install a boot loader (because you don t want to change the current boot loader), click Change Boot Loader and select Do Not Install a Boot Loader. (If the defaults are okay, skip the next step.) 14. Configure advanced boot loader. To choose where to store the boot loader, select one of the following: Master Boot Record (MBR) This is the preferred place for GRUB. It causes GRUB to control the boot process for all operating systems installed on the hard disk. First Sector of Boot Partition If another boot loader is being used on your computer, you can have GRUB installed on your Linux partition (first sector). This lets you have the other boot loader refer to your GRUB boot loader to boot Fedora Linux. You can choose to add kernel parameters (which may be needed if your computer can t detect certain hardware). Some of the kernel parameters you can use are described in Chapter 11 in descriptions of boot options. You can select to use linear mode (which was once required to boot from a partition on the disk that is above cylinder 1024 but is now rarely needed). Continue to the next step. Note
