Well, on some MSTE mobo's you need to do more than just insert the GALs and FPU, if I remember correctly there's also a resistor on the underside of the mobo that needs to be removed and possibly there was something else. Resistor on the underside or jumper W3 depending on the motherboard version.

Where did I write something like that? These are the only sources I have found in this topic (anything). You added EmuTOS, that's all. Rather, there is no book "Programming VGA cards from Atari level".
It's the equivalent of the Standard VGA driver, known in Windows. Why this mode? Because this is a sensible resolution (320x200 ? No). The standard VGA modes are on almost every ISA card, including those for which there are no drivers eg. Trident. http://www.harbaum.org/till/atari/index.html (STGA_SW)
Running the card in the standard VGA (12h) 640x480x16col mode. There are sources of drivers in C (without the use of DOS program interrupt). Registry programming. Even using PEEK and POKE in GFA, you can read and change them, but this is not enough. I don't have experience in this topic
