Resolving Memory Conflicts<br />
Note: This section does not apply to PCI Bus CompuScope<br />
cards.<br />
The following are several common sources of memory conflict<br />
for CompuScope boards.<br />
Please note that you may also try a clean boot in order to<br />
bypass your autoexec.bat and config.sys files and prevent any<br />
extra programs from loading at boot time. Press and hold the<br />
F5 key as soon as your screen displays the message “Starting<br />
MS-DOS.” You may also create a boot disk and boot from it<br />
instead. See your MS-DOS manual for details. Finally, you<br />
may use the GageScope ® for DOS Diagnostic Disk as a boot<br />
disk.<br />
Memory Managers<br />
GageScope ® for DOS requires a 4 kilobyte window in the upper<br />
memory block area to communicate with the on-board RAM of<br />
the CS250, CS225 and CSLITE, and an 8 kilobyte window for<br />
all other CompuScope cards.<br />
EMM386 is a memory manager used by DOS and Windows<br />
and is automatically installed by MEMMAKER when you<br />
choose to Optimize your system. EMM386 takes up all the<br />
upper memory blocks to install some of the Extended memory<br />
for running DOS drivers, TSRs, etc., so that there is no<br />
window in the upper memory left to be used by the<br />
CompuScope card.<br />
MEMMAKER changes the first line of the CONFIG.SYS file<br />
to:<br />
DEVICE=C:\DOS\EMM386.EXE NOEMS<br />
This means that all the upper memory blocks are automatically<br />
dedicated to loading TSRs and MS-DOS devices.<br />
