1)I have a S3 Trio V2 1MB PCI and OLD VGA 14" 640x480x256color
When the PC boot all is black/white (Award BIOS - blue backround too). Under DOS I run 4DOS and all "colored extensions" are on gray-scale too. DOS text progrmas are without colors too (NC, EDIT, ...). DOS graphic programs (games - Hexen, Quake, ...) are fully color. Windows'95 startup screen is color. Windows'95 (the OS/Shell - not the splash screen) is on gray-scale. oops: last is fixed with the S3V2 drivers from S3 page.
How to get colors under text-mode (DOS text mode) and at boot-up time (BIOS) - the last will surely slove the text-mode problem.
2) Are the PCI modems compatible with all software (DOS based)?
