Paradise PVGA1A, memory detection error and unsupported video modes #4840
Description
What happened?
I found two bugs:
- Windows 3.0 seems to work fine with 640x480 256 colors and 800x600 16 colors, but not in 1024x768 16 colors.
- Both Neopaint built-in Paradise drivers and the VESA PVGA1A1B detects only 256kb RAM even with 512kb.
Note:(I checked the drivers are for this card, these drivers supports 640x480x256, 800x600x16 and 1024x768x16
There are other drivers for the PVGA-11L that support for 800x600 256 colors and 1024x768 2 colors).
In fact, only the 640x480x256 and 1024x768x16 uses 512kb.
