I don't want to start a new topic so I'll write here.
I have an unusual problem with Voodoo2 that appeared recently (InnoVision MIghty II 3D 8MB).
When I run any game or program that uses Voodoo2 (Direct3D, OpenGL, GLlie), the PC speaker starts making random noises (beep....beep...), sometimes after a few seconds, sometimes right away, sometimes with longer pause, no any rule. This only happens when using Voodoo2, under Win98SE and under DOS (Tomb Raider 1), but when I run the same games on Matrox G400, everything is ok. I installed Voodoo2 about 2 months ago and everything was working fine until now.
I've tried everything, different PCI slots, different drivers, throwing variables from autoexec.bat, various changes in the BIOS.
The only thing I found is that when I install only 128MB of RAM (one module) in the PC, everything back to normal. But when I install 256MB (one module) I can hear the sounds, if it is 128+256 it is also bad, if it is 256+245+128MB it is also wrong. All memory tested with memtest86+, they are fine.
The voltages are rather ok, sometimes 5V drops to 4.6V (HWINFO), but this also happens when I use Matrox G400.
Could anyone advise what could happen that above 128MB the PC speaker makes sounds when using Voodoo2? Motherboard is dying?
The only simple solution I have is to disconnect the PC speaker 😀
I'm 99% sure it's a hardware problem, because under Dos Tomb Raider 1 uses the built-in glide in the .exe
