SUMMARY

The Reallocate Extended Memory Block function contained in the Extended Memory Specifications (XMS) has not yet been implemented for the HIMEM.SYS driver. Page 2-2 of the XMS documentation, in the section titled "Calling the API Functions," states that some of the XMS API functions may not be implemented by all drivers.

To obtain the XMS specifications, contact Microsoft Customer Information at (800) 426-9400.
