3. Choices

3.1. Architecture

The following is a summary of the architecture choices that you should consider. Your choice will probably depend most on your compuer expertise level, value of existing data, and expected division of usage between Windows and linux.

Separate for linux and WindowsShared by linux and WindowsSupportProsCons
 address spaceNot Supported. Windows must be the only operating system in its partition.  
address spacepartitionNot covered by this HOWTO. VMWare under WindowsNo need to disturb the current configuration. Linux can be loaded on the emulated system.linux is slow.

address spacepartitionNot covered by this HOWTO. Armed distribution (unverified)No need to disturb the current configuration. 
partitiondiskWindows requires that Windows reside in the first primary partitionWorks with standard mail-order home computers from the major dealers.Requires more installation effort.
diskhost Minimizes risk to existing system and data. Requires less installation effort.Normally requires a second computer and extra disks.
hostnetworkNot covered by this HOWTO. Classes, books, and online help is readily available.Minimizes installation effort.Requires at least two computers equipped with network interface cards. Data is not directly available to the other operating system.

3.2. Filesystems

Your choice of filesystem is usually constrained by the hard disk manufacturer, your choice of Windows version, and your choice of linux distribution.

Table 2. Filesystems

TypeCodeSupportDescription
DOS60x06Windows 95, Windows 98, Windows NT, linuxIBM DOS default filesystem. Names limited to eight characters + 3 character type
NTFS0x07Windows NT, linux read-onlyWindows NT default filesystem. Names have arbitrary length. Names cannot include special characters
FAT32 LBA0x0cWindows 95, Windows 98, Windows NT, linuxWindows95/98 default filesystem. Names have arbitrary length. Names cannot inlcude special characters
swap0x82linuxlinex default memory cache filesystem
ext20x83linuxlinux default filesystem. Names have arbitrary length. Names can contain arbitrary characters. Tends to suffer little external fragmentation. Scales well over several magnitudes of size. Runs quickly on semirandom access systems.

3.3. Linux Distribution

Your choice of distribution will depend mostly on friends' recommendations, your level of computer expertise, and easy availability of packages. Most distributions will happily reside on the same disk, so there is no reason not to try several distributions until you find the one that is best for you.

Table 3. Distributions

DistroPublisherSourceProsCons
RedHatRed Hat, Inc.http://www.redhat.com/Easy to install. Home-user-friendly. Commercial support available. Large number of bundled packages. Tolerates unbundled packages.Does not tolerate multiple versions on same partition.
SlackwareWalnut Creek CDROMhttp://www.slackware.org/Largest number of bundled packages. Professional-user-friendly. Easiest software development. New packages most often appear here first. Tolerates unbundled packages. Tolerates multiple versions on same partition.Moderate computer expertise required.
SuSESuSE Gmbhhttp://www.suse.com/Easy to install. Business-user-friendly. Aimed at business users. Commercial support available. Tolerates unbundled packages. Tolerates multiple versions on same partition. 

3.4. Backup Tools

ToolRequirementsDescription
Norton GhostWindows 95/98/NT network driveEasy to use. Makes and restores images of disks or partitions. No selection or deselection of files/directories. No index generated.
toblinux tape driveEasy to use. Easy to configure. Selects or deselects files/directories to backup or restore. Generates index of backups searchable to find archived files.
yast (untested)backup toolGraphical interface for system administration tools. Included with SuSE linux

3.5. Compaction Tools

Table 5. Compaction Tools

ToolRequirementsDescription
fipsWindows95 (Included in tomsrtbt-1.6.335)Splits a FAT16 or FAT32 partition into two partitions without destroying data so that the new partition can be loaded with a different operating system.
fipsWindows98, Windows98 (requires at least version 2.0), Run under Windows98Splits a FAT16 or FAT32 partition into two partitions without destroying data so that the new partition can be loaded with a different operating system.

3.6. Repartitioning Tools

Table 6. Repartitioning Tools

ToolRequirementsDescription
fdiskIncluded in tomsrtbt-1.6.335Supports editting of a partition table. Two-tiered menu system. The first level includes read and normal operations. The second level lets you fix inconsistencies.
fdiskIncluded with Windows 95 and Windows 98Does not permit creattion of partitios associated with filesystems not supported by Windows, nor selecting a bootable partition other than the first primary partition.
yast (untested)backup toolGraphical interface for system administration tools. Included with SuSE linux

3.7. Formating Tools

Table 7. Formating Tools

ToolRequirementsDescription
e2fsckIncluded in tomsrtbt-1.6.335Checks an ext2 filesystem for errors
formatIncluded with Windows 95 and Windows 98Creates a vfat filesystem on a chosen partition
mke2fsIncluded in tomsrtbt-1.6.335Creates an ext2 filesystem on a chosen partition.
mkswapIncluded in tomsrtbt-1.6.335Creates a swap filesystem on a chosen partition.

3.8. Boot Managers

Table 8. Boot Managers

ToolRequirementsDescription
lilolinuxConfigures which operating system is booted. lilo itself if very robust and configurable. Some care is required, since lilo is usually used to overwrite the master boot record, lest one carelessly loose the ability to boot Windows automatically.
loadlin (uc)Windws 95 or 98Started from Windows in dos mode. (Can be placed as shortcut in Windows) Replaces linux with Windows in memory. Since loadlin does not overwrite the master boot record, a failed installation should not be able to risk Windows.
