Mwave Resources

MWAVE Resources

The Mwave card has an established number of resources at it's disposal. The Mwave software drivers tell the card exactly how many resources the card has at system startup, and the card operates within this boundary. If the software communicates too low of a number, the card may believe that it does not have enough resources to complete an instruction and it will slow down. If the number is too high, the card may loose information or crash the entire system. Further, a program or programs that use Mwave but which are not needed by the computer user are consuming Mwave resources needlessly and possibly causing waiting periods for other programs. There are several steps that can be taken to insure your Mwave has adequate resources at its disposal. By far the most effective is overclocking.
Mwave Overclocking

Presumably out of interest in providing customers with a stable product, IBM shipped the Aptiva with the Mwave resources set at a very safe (and low) level. Unfortunately, the number is so low that the card has difficulty playing sounds and running the modem at 28800 connections without system slowdown. To remedy this situation, it is possible to tell the Mwave card that is has a higher number of resources available. This enables smoother online sessions, quicker wav file response, and clearer MIDI while online. It also allows for better use of Internet products that use streaming audio, such as RealAudio. Unfortunately, as I mentioned before, if the resources are set too high the system may crash. It will not permanently damage the computer, but you will have to re-start.
To overclock your Mwave card, follow these steps carefully:

Find all instances of the file MWAVE.INI on your hard disk.
Use Notepad or another text editor to open these files.
Find the line reading: IPS=24900000. This is the line that tells the card how many resources are available.
Change 24900000 to something between 25000000 and 30000000
In my experience, the most stable number is 27000000. Anything closer to 30000000 and the system may crash.
Save the files and restart your system. Your Mwave is now overclocked.

Disabling Caller ID
The Mwave program that monitors incoming calls for content and directs them to the correct program uses Mwave resources to check the line for Caller ID information. If you don't use Caller ID or don't have access to it, consider disabling the option to free up those resources. To do this, complete the following steps:

Open Windows Explorer or File Manager.
Locate the file "callerid.dsp". It is usually in the MWW\Modem directory.
Change the name of the file to "callerid.ds0" or something similar.
Restart your system.

After you complete these steps, run the program "discapp.exe". It is usually in the same directory as the "callerid.dsp" was located. Under the OPTIONS menu, the CALLER ID option should be grayed out. If it is, you have successfully disabled Caller ID. If you wish to use Caller ID in the future, you wall have to restore the original name of the above described DSP file. Thanks to [email protected] for this hint.
