When the system boots up, it reports either 128 KB or 384 KB less memory than is in the system

Explanation: The system is reporting approximately the right amount of memory when it boots, but is leaving out either 128 KB or 384 KB in its report.

Diagnosis: This is normal for many types of machines. The "missing" memory is the area of RAM between conventional memory and extended memory, called the upper memory area. It is not available for use by most standard programs, and therefore some BIOSes choose not to report it.

Recommendation: No action required.
