- Before OpenLinux can be installed, you must create <a
- href="def_partition.qml">partitions</a> for it to reside on. Usually
- you will want at least 2 partitions, one for the OpenLinux <a
- href="def_rootpart.qml">root</a> partition, and one for the OpenLinux <a
- href="def_linux-swap.qml">swap</a> partition. More partitions can be
- mounted to other directories in the OpenLinux filesystem, such as the
- users' local storage space (/home) residing on its own partition, as
- described in the <a href="fdisk.qml#Mount Point">Mount Point</a>
- section.

- On the hard disk partitioning screen, you will see a window which
- includes information about your hard disk. Each column is described
- in more detail below.
- </p>
- <h3>
- <a name="Device">
- Device
- </a>
- </h3>
- <p>
- Each device name in the <strong>Device</strong> column refers to a hard
- disk, CDROM drive, or other partitionable device. Partitions on each
- device are also included. Device names for drives and partitions in
- OpenLinux are as follows.
- </p>
- <ul>
- <li>
- IDE/ATAPI devices
- </li>
- <ul>
- <li>
- <strong>/dev/hda</strong> = Primary IDE channel, Master Device
- </li>
- <li>
- <strong>/dev/hdb</strong> = Primary IDE channel, Slave Device
- </li>
- <li>
- <strong>/dev/hdc</strong> = Secondary IDE channel, Master Device
- </li>
- <li>
- <strong>/dev/hdd</strong> = Secondary IDE channel, Slave Device
- </li>
- </ul>
- <li>
- SCSI devices
- </li>
- <ul>
- <li>
- <strong>/dev/sda</strong> = The first SCSI hard disk/CDROM drive
- </li>
- <li>
- <strong>/dev/sdb</strong> = The second SCSI hard disk/CDROM drive
- </li>
- <li>
- <strong>/dev/sdc</strong> = The third SCSI hard disk/CDROM drive
- </li>
- <li>
- and so on.
- </li>
- </ul>
- </ul>
- <p>
- Most pre-built systems include one IDE hard disk and one ATAPI CDROM
- drive. On those systems, the default is usually to have the IDE hard
- disk as the Primary Master device, or <strong>/dev/hda</strong>, and the
- CDROM drive as the Secondary Master device, or <strong>/dev/hdc</strong>.
- </p>
- <p>
- Each drive is divided into partitions. However, before using such
- partitions, they must be initialized, or formatted, in a certain way
- depending on what type of data will be stored on them. Those system
- types are described in the <a href="fdisk.qml#System">System</a> section
- below.
- </p>
- <p>
- The convention for referencing paritions on each hard drive is to simply
- append a number to the end of the disk's device name, starting with 1
- (one). For example, the first partition on the Primary Master IDE disk
- is referenced by <strong>/dev/hda1</strong>, the second partition on
- the same disk is <strong>/dev/hda2</strong>, and so on.
- </p>
- <h3>
- <a name="Start">
- Start
- </a>
- </h3>
- <p>
- The <strong>Start</strong> column refers to the corresponding
- partition's (or disk's) starting <a href="def_sectors.qml">sector</a>.
- For example, if /dev/hda1 starts at the beginning of the disk, its
- starting sector will be 1.
- </p>
- <p>
- See also: <a href="fdisk.qml#End">End</a>
- </p>
- <h3>
- <a name="End">
- End
- </a>
- </h3>
- <p>
- The <strong>End</strong> column is much like the <a
- href="fdisk.qml#Start">Start</a> column, except that it designates the
- ending <a href="def_sectors.qml">sector</a> of the partition or disk.
- The <strong>Start</strong> and <strong>End</strong> sectors represent the
- <a href="def_sector-range.qml">range</a> of sectors a specific
- partition or disk uses.
- </p>
- <h3>
- <a name="Size">
- Size
- </a>
- </h3>
- <p>
- The <strong>Size</strong> column contains the current size of the
- corresponding partition. MB is used to represent megabytes.
- </p>
- <h3>
- <a name="System">
- System
- </a>
- </h3>
- <p>
- The <strong>System</strong> column contains the type of system for
- which the partition will be formatted. Before a partition can be used
- to store data or contain an operating system, it must be formatted. The
- available types of formatting are
- <ul>
- <li>
- <a href="def_linux-native.qml">Linux Native</a>
- </li>
- <li>
- <a href="def_linux-swap.qml">Linux Swap</a>
- </li>
- <li>
- <a href="def_extended.qml">Extended</a>
- </li>
- <li>
- <a href="def_doswin.qml">DOS / Windows</a>
- </li>
- </ul>
- </p>
- <h3>
- <a name="Bootable">
- Bootable
- </a>
- </h3>
- <p>
- The <strong>bootable</strong> column represents whether the
- corresponding partition will be bootable or not. Normally you will only
- want <strong>one</strong> bootable partition, since most systems will not
- know what to do if they find more than one.
- </p>
- <h3>
- <a name="Mount Point">
- Mount Point
- </a>
- </h3>
- <p>
- The <strong>mount point</strong> column is used to display to what
- directory the corresponding partition will be mounted. For example,
- you could have all users' home directories on a separate partition (for
- safety or reuse between systems) by specifying <strong>/home</strong> as
- the mount point. One partition must be designated as the
- <a href="def_rootpart.qml">root</a> ('/') partition.
- </p>
- <h3>
- <a name="Formatting">
- Formatting
- </a>
- </h3>
- <p>
- The <strong>formatting</strong> column designates whether the
- corresponding partition will be formatted or not. If you have data
- that will be used in the new OpenLinux system but is not
- to be formatted (such as in users' home directories), make sure this is
- set to "no" using the <a href="fdisk.qml#Edit">Edit</a> feature.
- </p>
- <h2>
- <a name="Button Description">
- Button Description
- </a>
- </h2>
- <h3>
- <a name="Edit">
- Edit
- </a>
- </h3>
- <p>
- The <strong>edit</strong> button is used when changing the parameters of
- a partition. The parameters that can be changed are the
- <a href="fdisk.qml#Start">Start</a> and <a href="fdisk.qml#End">End</a>
- sectors, the <a href="fdisk.qml#System">System</a> type, the
- <a href="fdisk.qml#Mount Point">mount point</a>, the
- <a href="fdisk.qml#Bootable">bootable</a> flag, and whether the partition
- should be <a href="fdisk.qml#Formatting">formatted</a> or not. Some
- partitions must be formatted, such as the <a href="def_rootpart.qml">root
- </a> partition.
- </p>
- <h3>
- <a name="Delete">
- Delete
- </a>
- </h3>
- <p>
- The <strong>delete</strong> button is used for deleting the parameters
- on a partition. If you wish to reset a partitions settings, then
- click this button.
- </p>
- <h3>
- <a name="Add Logical">
- Add Logical
- </a>
- </h3>
- <p>
- The <strong>add logical</strong> button can be used to create a <a
- href="def_logical.qml">logical</a> partition within an
- <a href="def_extended.qml">extended</a> partition. You can only create a
- logical partition if an extended partition is present.
- </p>
- <h3>
- <a name="Write">
- Write
- </a>
- </h3>
- <p>
- The <strong>write</strong> button is used to save the current
- partition information to the disk's partition tables. You must write the
- partition information before the <strong>next</strong> button will be
- available and continuing.
- </p>
- <h3>
- <a name="Reset">
- Reset
- </a>
- </h3>
- <p>
- The <strong>reset</strong> button is used to change the
- partition settings back to what they originally were before entering this
- screen. Think of this as an "undo all changes" button.
