SYMPTOMS
An expanded memory page frame set to DC00 or higher on a AT&T 6386E causes the system to stop responding (hang). For example, the following DEVICE= statement hangs the system.

DEVICE=EMM386.EXE m8 RAM



CAUSE
The AT&T 6386E has a ROM option at address E800 that is used during system operations. Setting a page frame to DC00 or higher overlaps with the ROM option, resulting in a hang.



MORE INFORMATION
On some systems, you can set a page frame to DC00 or higher. For example, machines with AMI BIOS use the entire E000:EFFF area for the ROM setup program. To set a page frame at E000, make sure that the ROM option is never needed during normal system operation.

The product included here is manufactured by AT&T, a vendor independent of Microsoft; we make no warranty, implied or otherwise, regarding this product's performance or reliability.
