I have a new Pentium MMX 233 PC (Chaintech Mainboard) with Matrox Millennium II PCI video board, Sound Blaster AWE 64 Gold and Windows 95.
Windows 95 tells that there is a "Problem with the screen settings. The type of video board is not correct or the current settings are not right for the hardware. [Click OK]" when I use Matrox drivers v3.60 or v3.80 or even standard Windows SVGA drivers at resolutions or color depth greater than 640x480 16 colours. When I get this message the screen appears in 640x480 16 colours even if I set it to, by example, 800x600 32 bit colours. Please note that when I installed Matrox drivers the first time I re-booted the PC I got the right resolution (800x600 32 bit), but in the following reboots the PC had some problems: 1) Windows stops loading when its desktop and the mouse icon appear (the screen flashes once and the mouse and keyboard are stuck) or 2) I get the previous error message.
In the Award BIOS even if I enabled "Assign IRQ for VGA" the problem was still there.
Is this a hardware/BIOS problem in some component (mainboard, video)? Today I will try with another video board (S3).
Please note that this problem appeared after connecting a Logitech Cordless PS/2 Mouse to mainboard's PS/2 port! Is there a conflict between PS/2 port (IRQ 12) and something else??? With the same mouse connected to the serial port there is no problem (I think)!
