- A very common problem on PC's is the following:
-
- If you use QEMM, EMM386 or any other Memory Manager,
- or with MS-Windows, or sometimes even with the BIOS setup to shadowing,
- you get memory mapped over the Ethnercard memory.
-
- Especially any Memory Manager, which seeks between the adapters for
- free memory did not see the memory on your WD8003, as its mapped in
- when TCP kernel starts.
-
- Its very important to EXCLUDE the memory on your WD8003 from the
- QEMM of whatever you use, or will see effects like those you decribed,
- or even more cumbersome.
-
- This is really the main reason for failure of networking software
- on PC's at our site. People install some software (like DOS5.0 with EMM),
- and some days later they complain that the network isn't working.
- Ask them if they changed something, and they will tell you they did
- nothing!
