Dude:
If you get the BIOS numbers (on the bottom of the first screen when you boot up), we should be able to determine who the mboard manufacturer actually was (never heard of IMiracle as a MANUFACTURER) ... and from there can do some research to come up with the original video driver for the board. Using a 'generic' S3 or Trident whatever driver is NOT going to be your answer ... each chip and mboard configuration acts differently.
For now, have you tried the 'generic' windows VGA driver that comes with W95 ??
