SYMPTOMS

If you run the MS-DOS MemMaker utility on a system with a Periscope board, the following error message may be displayed:

SIZER: UMB's overran list buffer.

CAUSE

MemMaker detects the first 24 kilobytes (K) of protected memory used by the Periscope board, but does not detect the last 8K. Therefore, when MemMaker adds the x= parameter, it does not exclude a large enough range.

WORKAROUND

To work around this problem, add the x= switch to the device= line for EMM386 to exclude the C800-CFFF range. For example:
   device=c:\dos\emm386.exe x=c800-cfff
