Linux is fast becoming viewed by some as an acceptable alternative to the Windows NT operating system. As such, Compaq now supports this operating system on many of its servers, workstations, desktops and portables. Many customers are using Linux to perform various functions throughout their corporation. The Linux operating system was originally developed on desktop Intel Architecture systems. As such, Linux was developed without portable features. Recently, Linux added support for features that portable users expect such as Advanced Power Management (APM), PCMCIA cards, and XWindows video drivers for LCD panels. Many other features of portables are so implementationdependent and have no analogy in the desktop world that the Linux developers have not considered adding these features. For example, each portable manufacturer has their own implementation of device swapping and docking stations.

Linux Hardware Requirements
The Linux kernel small size and its efficient memory management contribute to Linux low s s hardware requirements. If run in a text-based mode, Linux requires less processing power for graphics, unless X-Windows or a Graphical User Interface (GUI) is used. Depending on the type of GUI used, the minimum hardware requirements will vary slightly for each distribution of Linux. Table 10 outlines the minimum hardware requirements for running Red Hat Linux 5.2.
Table 10 Minimum Hardware Requirements for Red Hat Linux 5.2
Requirement Intel 386SX processor 16MB memory 120MB Hard Disk Drive for a minimal custom Most video cards supported CD-ROM drive 3.5" floppy disk drive
Linux Feature Considerations
Linux has most major features and subsystems of a modern-day Unix operating system, including (but not limited to) NFS, TCP/IP, X-Windows, send-mail, BIND, shell command-line interpreters, editors, and other tools that the Unix market expects. Additionally, Linux has a large amount of Microsoft compatibility in the form of file system support, PCX networking, and floppy management utilities.
Refer to http://www.redhat.com/support/docs/hardware.html for additional information

Frequently Asked Questions
What is the difference between ACPI and APM?
Windows 98 and Windows 2000 support the Advanced Configuration and Power Interface (ACPI) specification. Advanced Power Management (APM) utilized the BIOS for power management. ACPI places the power management functionality inside of the operating system architecture. When using ACPI-aware software application and hardware devices, ACPI is expected to provide more efficient power management over APM. ACPI is also a key element of the Microsoft OnNow initiative, which promises to make computers more responsive. ACPI may provide more efficient power management, faster program startup and shutdown times, and quicker computer boot and shutdown to name just a few features of ACPI technology. ACPI requires support in the hardware, the BIOS, and the operating system. Windows 98 and Windows 2000 are the first operating systems to implement ACPI. Compaq recommends that Windows 98 customers who wish to use ACPI on Compaq Armada products upgrade to Windows 98 Second Edition or later. Most Armada platforms have ACPI hardware support and BIOS support, although in some cases, a BIOS upgrade may be required to enable BIOS support. With Windows 98 Second Edition, ACPI will automatically be enabled on ACPI-capable platforms with a BIOS dated after 12/31/99. ACPI can easily be enabled on platforms with an earlier BIOS, provided the BIOS contains ACPI support. With Windows 2000, ACPI will be automatically enabled (on ACPI-enabled platforms) when Windows 2000 is installed.
Is Windows 98 a major upgrade to Windows 95?
Windows 98 is an evolutionary enhancement to Windows 95 that includes some new feature and support for new hardware technologies. Windows 98 features an integrated operating system and browser, faster launch and shutdown times, expanded driver support and update, updated system tools for corporate support, and troubleshooting wizards. With these enhancements, Windows 98 works better and plays better according to Microsoft.

Is Windows 2000 a major upgrade to Windows NT 4.0?
Windows 2000 is a revolutionary upgrade to Windows NT 4.0 users, particularly mobile users. Many of the features previously offered through Compaq value-add are now inherent in the operating system. In addition, Windows 2000 offers many security and remote management feature not previously seen on any Microsoft operating system.
Should I upgrade to Windows 98, Windows NT 4.0 or wait for Windows 2000?
Microsoft recommends Windows 2000 as the premier operating system for business users. Until Windows 2000 is available, Windows NT 4.0 is the current operating system of choice for many commercial users. That said, Windows 98 may still be appropriate for other commercial users who require new features or hardware support in Windows 98, but who have decided against Windows NT in the near term. Compaq is committed to supporting Windows 98 and Windows

2000 on the Armada family of notebooks. This commitment is based on the premise that customers should be able to choose the operating system that is most appropriate for them and rest assured that Compaq will support their decision.
What features are not supported under Microsoft Windows 95 OSR1?
Compaq only supports those hardware features inherently supported under Windows 95 OSR1. New types of hardware supported under Windows 95 OSR2, such as 32-bit CardBus PC Cards, cannot be supported under Windows 95 OSR1. For customers who require access to the latest hardware functionality it is recommended that they keep the version of Windows 95 OSR2 preinstalled by Compaq.
Why isn OS/2 Warp supported on the Armada 1500 family? t
OS/2 Warp is supported on the Armada 4100, 7300 and 7700 families. For Compaq customers using OS/2 on portable platforms, these products offer performance and mobility features that are better suited to an OS/2 environment than the Armada 1500 family.
Does IBM offer support for OS/2 Warp on Compaq portable products?
Yes, IBM does offer support for OS/2 on Compaq portable products. Customers with questions that relate to specific IBM OS/2 upgrades, enhancements or patches should contact IBM directly. For questions about enabling basic hardware functionality inherently supported by OS/2 Warp 3.0 or questions regarding Compaq software enhancements for OS/2 Warp 3.0, customers should contact Compaq Customer Service & Support.
Does Compaq support UNIX on any portable platforms?
Compaq does not support any version of UNIX on its portable computers. Customers who wish to use UNIX on a Compaq portable should contact the operating system vendor directly for support.
Does Compaq support Linux on any portable platforms?
Compaq does support Linux on Armada 7400 and 7400 product families. Customers who wish to use Linux on a Compaq portable should refer to the white paper titled Linux Support on Compaq Armada 7400 and 7800.
