DOCUMENT:Q78973 07-NOV-1999 [win95x] TITLE :Using the DFI HS 3000 Plus Scanner in Enhanced Mode PRODUCT :Microsoft Windows 95.x Retail Product PROD/VER:WINDOWS:3.0,3.0a,3.1,3.11 OPER/SYS: KEYWORDS: ====================================================================== ------------------------------------------------------------------------------- The information in this article applies to: - Microsoft Windows versions 3.0, 3.0a, 3.1, 3.11 ------------------------------------------------------------------------------- SYMPTOMS ======== When running Microsoft Windows in 386 enhanced mode in conjunction with the DFI's scanner program (SCAN.EXE) that comes with the DFI HS 3000 Plus Scanner, you may get the following error message: DMA buffer too small, set DmaBufferSize entry in SYSTEM.INI to XXX CAUSE ===== The DmaBufferSize line may need to be added in the [386Enh] section of the SYSTEM.INI file so that the DFI scanner program can run. RESOLUTION ========== To make the adjustment: 1. Switch to the directory that contains the SYSTEM.INI file. 2. Run Notepad and open SYSTEM.INI. 3. Locate the [386Enh] section. 4. Add the line DMABufferSize=XXX where XXX = the size stated in the error message 5. Save the new changes to the SYSTEM.INI file, exit Windows, and then restart Windows for the changes to take effect. MORE INFORMATION ================ DMABufferSize specifies the amount of memory (in kilobytes) to be reserved for buffered direct memory access (DMA). This memory is allocated above 640K, if possible. Windows in 386 enhanced mode defaults to a DMA buffer size that handles disk access. The default setting size is 16. To change the value, add the line above to the [386Enh] section.
