Another bozo BIOS setting (earlier its was video BIOS shadowing) and now "Plug and Play Aware O/S" ,  the setting is " Yes"  if the O/s is P&P aware. But now I was told it should be set to  NO. What should be the correct setting YES or NO for my O/s  which is WinMe.

You are running Windows ME.  Which is a PnP Aware OS.  I would suggest saying Yes.  If you need to assign a device or devices it's own IRQ.  Then you should hit No.  Generally it is best to set it as Yes if you are running a PnP OS.

I was told that PnP devices will auto configure and it won't hurt a thing or lose nothing because PC will still autoconfigure PnP devices, and will make the system more stable.

it is better for the OS to assign IRQ's to hardware.  But be aware that if you swap from yes to no Windows will try to reinstall most of the drivers and sometimes it can cause problems on the system.

I found some info on PnP but it was for Win2000 and I'm not sure whether it applies for Win9x

Please check this out..

...."The Plug and Play operating system settings in the computer's BIOS should not affect how Windows handles the hardware in general. However, Microsoft recommends that you set this setting to "No" or "Disabled" in the computer's BIOS...."

That is basically for windows 2000.

This link here says that if you have installed Win9x with the PnP setting to yes, then you should leave it at yes.
http://www.tldp.org/HOWTO/Plug-and-Play-HOWTO-4.html

This is what MSI says:

PnP/PCI Configurations
PnP OS Installed ( Yes/No )
When set to YES, BIOS will only initialize the PnP cards used for booting (VGA, IDE, SCSI). The rest of the cards will be initialized by the PnP operating system like Windows 95/98. If you're Operating System support PnP (Plug N Play) like Windows 95/98, set as Yes
