The memory test performed by HIMEM.SYS version 3.10 may fail (possibly causing your system to stop responding [hang]) if your machine uses a hardware cache controller.


Some hardware cache controllers do not handle 16-megabyte and 32-megabyte memory boundaries well. As a result, the HIMEM.SYS memory test fails.


To work around this problem, disable the hardware cache controller or contact your hardware vendor for assistance.
