MORE INFORMATION
When you start your computer, the BIOS checks the system-specific settings that are stored in the complementary metal-oxide semiconductor (CMOS) chip. You can modify these settings as your computer or your needs change.

Delayed Write Failure
Data corruption may occur if the Large System Cache feature is enabled in Windows XP. This problem does not occur on all systems. The key ingredients that lead to data corruption may include: ? System Memory greater than 512 Meg. (1 gigabyte of RAM is common)
? Large NTFS disk volumes and multiple large volumes. (60-100 gigabyte hard drives possibly in RAID arrays)
? AGP graphics with large AGP resource requirements (AGP aperture greater than default)
? Large file transfers. This problem occurs when the computer runs out of system page table entries. Windows determines (at boot time) the default number of page table entries to assign, based on the amount of system memory available.
The conditions listed above all contribute to increasing the number of page table entries that Windows XP must maintain and in extreme cases the page table entries may be exhausted. To avoid this problem ensure the System Cache option is NOT selected for Memory usage.
To do this, follow these steps: 1. Click Start, right-click My Computer, and then click Properties to open the System Properties dialog box.
2. Click the Advanced tab, and then under Performance click Settings.
3. Under Performance Options, click the Advanced tab.
4. Under Memory Usage, click to select Programs, if it is not already selected.
5. Click OK.
