SYMPTOMS
An AST EISA computer with 16 megabytes (MB) or more RAM has the "Stop Scanning Memory Above 16 Meg" option enabled may cause Windows NT to generate a STOP message with kernel trap errors.

CAUSE
AST EISA computers have an option, "Stop Scanning Memory Above 16 Meg," that is enabled by default. If this setting is enabled on computers that have 16 MB or more of physical RAM installed, Windows NT may exhibit a kernel trap error upon booting of the system. 16 MB is actually 16384 kilobytes (K), so it appears that NTDETECT was correctly detecting the full 16384K. However, the EISA configuration is only reporting available memory to 16000K, which causes the above error message to occur.

RESOLUTION
To prevent the error messages, disable the "Stop Scanning Memory Above 16 Meg" option with the EISA configuration utility disk that is supplied by the manufacturer.

AST EISA computers are manufactured by AST Research, Inc., a vendor independent of Microsoft; we make no warranty, implied or otherwise, regarding these products' performance or reliability.
