Hi! I hope one of you people here has a suggestion to this: Someone posted the program remac onto comp.binaries.ibm.pc, and it really works fine, except for one thing. It only works 100% fine at boot-up time, i.e. if I start it from the autoexec.bat. If I use the prog at a later stage, even RIGHT AFTER boot-up is finished, then I get this nasty buzz in my speaker. My suspicion is, that somwhere inside the circuits, some currents build up, which then go into the speaker if I use it. It almost drowns out any sound coming from the speaker. I know other computers don't have that problem, coz I've tested the prog on the PS/2's, and it worked fine (without that buzz) at any time. Any ideas? (capacitors, resistors,...)

(capacitors, resistors,...) Do you have a bus mouse installed? Try removing the driver... (the bus mouse generates a lot of interrupts and will prevent correct timing of sounds) -- Massimo Fasciano (fasciano@iro.umontreal.ca)

There is no volume control on the PC speaker. You can either disconnect it or put in a switch to disconnect/connect it. Either operation is simple and can be done cheaply. The first option is real easy and cheap. Open the case, find the wire leading from the speaker and pull it loose.

Just get a potentiometer of about 50-100 ohms, and connect it in as follows: - The two wires from the motherboard go to the two ends of the resistance. - One wire from the speaker goes to the sliding tap. - The other wire goes to one end of the resistance (sharing that lug with one of the wires from the motherboard). Experiment a little. One end will give you an "off" position in the full-counterclockwise position (what you want); the other will have it at full-clockwise. The hardest part is the carpentry on the case, if you decide you want to adjust the volume from the outside. The same is true for the on-off switch. Cheers! Dave
