Operation (Compaq Tru64 UNIX)

7.1 Introduction

This chapter provides information about post-installation tasks and use of the OpenGL drivers with a PowerStorm 300/350 PCI graphics controller on the Compaq Tru64 UNIX platform.

7.2 After Installation

After you have installed the PowerStorm 300/350 driver, you may wish to adjust the screen resolution and refresh rate, to alter the buffer swap synchronization or the default texel size, or to identify the driver version for troubleshooting purposes. The following sections describe how to perform these tasks.

7.2.1 Changing the Screen Resolution and Refresh Rate

The screen resolution and refresh rates are collectively referred to as the video mode. Table 5-1andTable 5-3 indicate which video modes are supported by the PowerStorm 300 PCI and PowerStorm 350 PCI graphic controllers, respectively (the resolutions are the same for Tru64 UNIX and Windows NT). Note that the PowerStorm 350 PCI graphics controller has twice as much frame buffer memory, and can thus support some higher resolutions than the PowerStorm 300 PCI graphics controller.

The default video mode is 1280x1024 pixels at 75 Hz. Before changing the video mode, verify that your monitor can handle the new parameters. Refer to your monitor documentation for this information. Then perform the following steps:

1.Login to the system as root. Ensure that no other user is currently working locally at the X console or connected remotely to the X server. You may choose to reboot the system in single-user mode before continuing.

2.Edit the file /var/X11/Xserver.conf. Save a backup copy.

The 486 architecture enabled users to run more complex applications, enhancing productivity and making it suitable for tasks ranging from word processing to graphics editing.

In terms of memory, the Compaq 300 supported up to 16MB of RAM, which was substantial for its time, allowing seamless multitasking of programs. The system typically included a 120MB IDE hard drive, which facilitated ample storage for documents and software, a critical aspect for users who needed to manage large volumes of data.

The Compaq 300 featured an integrated graphics card based on the popular VGA standard, enabling clear display quality for applications and gaming. Notably, its 14-inch CRT monitor that accompanied the system offered crisp visuals and an optimal viewing experience for users.

Another characteristic of the Compaq 300 was its expandability. The desktop came equipped with several expansion slots, allowing users to easily add components such as sound cards, network cards, or additional storage drives. This feature provided users with the flexibility to upgrade their systems as technology evolved, ensuring longevity in a rapidly changing landscape.

The Compaq 300 also showcased advanced connectivity options for its time. It included multiple serial and parallel ports, providing versatile connectivity with peripherals like printers, scanners, and modems. This adaptability was crucial, especially as businesses began to integrate more technology into their operations.

Durability and reliability were hallmarks of Compaq's design philosophy, and the Compaq 300 was no exception. Its solid construction and dependable components appealed to users who required a trustworthy system for daily tasks.

Overall, the Compaq 300 epitomized the intersection of performance, expandability, and reliability in desktop computing. Its innovative features and thoughtful design paved the way for future developments in the personal computer industry, making it a noteworthy entry in the history of computing technology.
