Exactly! Plus some int vectors, which I can easily identify as they are pointing to a vbios seg. Now I am getting that vectors together with 0x40:00-ff from /dev/mem, skipping the INIT and opening the high ports and... - I have a full-screen VESA! There are still some minor problems to resolve, but I expect to get the new video startup code within a few weeks, just let me play full-screen GTA a little:) Oh, and there is still one very bad thing, which is that we can't open the high ports in a fast mode (or can we?), so sometimes it works even slower than xdos... why ioperm() doesn't allow >0x3ff ports?..
