I have a Hercules graphics board for my IBM PC. Everything works as I would
expect, but I can hear a faint chirping noise coming from the speaker
whenever the screen is changing. I am serious - others will verify I am not
imagining it. This happens whether I am using text or graphics mode,
although it is a little worse in graphics. I took it to the local Computerland
and they said they have heard it in a few others and not to worry about it.
I am willing to do that, since everything is working fine, but I'm still a
bit worried that some subtle timing or coupling problem isn't at fault that
might get worse when I add more option cards someday. All I have now is the
Hercules and the floppy controller cards. I didn't buy the standard mono
adapter board so I can not test whether it causes chirping too. Any comments?
