Typically, your operating system's start-up files (such as config.sys and autoexec.bat) contain commands to start TSR programs when you boot your computer. If you suspect that one of these TSR programs is causing a memory conflict, remove the commands that start them from the start-up files. If the problem you were experiencing does not recur, one of the TSR programs probably created the conflict. Add the TSR commands back into the start-up files one at a time until you identify which TSR program is creating the conflict.

Program Conflicts

Some programs may leave portions of their setup information behind, even though you have exited from them. As a result, other programs cannot run. Rebooting your computer can confirm whether or not these programs are the cause of the problem.

Memory Address Conflicts

Memory address conflicts occur when two or more devices try to access the same address in the upper memory blocks (UMB). For example, if a network expansion card and an expanded-memory page frame are assigned an overlapping block of addresses, a memory address conflict arises. As a result, when you try to log in to the network, the operation fails.

To resolve this type of conflict, you can change the address of one of the devices. For example, in the case of the network expansion card and expanded-memory page frame address conflict, you can move the network card to an address block in the range of CC000h through D0000h. To reassign the expansion card's address block, refer to the documentation for the card.

Interrupt Assignment Conflicts

Problems can arise if two devices attempt to use the same interrupt request (IRQ) line. To avoid this type of conflict, check the documentation for the default IRQ-line setting for each installed expansion card. Then consult the following table to configure the card for one of the available IRQ lines.

This processor was available in various speeds, enabling users to select the model that best met their processing needs. The GX240 also offered ample memory options, supporting up to 2GB of SDRAM, which was considerable for its era, allowing for smoother multitasking and application performance.

The design of the GX240 was practical, featuring a compact, space-saving chassis ideal for office environments. It was designed for easy serviceability, with tool-less access to components, facilitating quick upgrades or repairs. The system was equipped with various configurations, enabling customers to customize it with multiple hard drive options, typically using IDE drives, which provided sufficient storage for everyday tasks.

The desktop utilized a variety of expansion slots, including AGP for graphics cards and PCI slots for additional peripherals. This expandability was crucial for businesses needing to adapt or enhance their systems over time. Integrated Intel graphics were standard, but users could opt for dedicated graphics cards to meet more demanding graphical needs.

Connectivity was also a strong point for the GX240, featuring multiple USB 2.0 ports, a serial port, and audio input/output capabilities. These ports allowed for seamless integration with various peripherals and devices, essential for a productive work environment. The GX240 also supported network connectivity through a built-in Ethernet controller, making it well-suited for office use, especially in networked environments.

In terms of software, the GX240 was usually shipped with Microsoft Windows XP, ensuring users had access to a stable and user-friendly operating system. This operating system not only provided compatibility with a wide range of applications but also enhanced the overall user experience.

In conclusion, the Dell GX240 was a solid desktop choice for businesses in the early 2000s, combining performance, upgradability, and a compact design. Its Intel Pentium 4 processor and ample memory options made it suitable for various tasks, while its space-saving design and expansion capabilities allowed businesses to adapt the system to their evolving needs.
