Hi folks. Finally I got a program that emulates Linear Frame Buffer (LFB) by means of Page Translation (Protected Mode feature for those who doesn't know). The program uses either VESA Protected Mode Interface (VESA 2.0+ cards) if available or calls a real-mode VESA BIOS function in a v86 mode on VESA 1.2+ cards (for more info on v86 refer to basic texts on Protected Mode). If anyone is interested in LFBemu 2.0, everything (text documentation, source code, executables) is available here: http://alexfru.chat.ru/programming/lfbemu20.zip If anybody wants to fit this thing into any of existing DPMI host (like CWSDPMI or WDOSX or something else), it would be just great. Because this way we can get some programs that require LFB working! Bye. P.S. people whom I sent LFBemu 1.0 should download v 2.0 because it has ability of switching banks in a v86 task and IRQs are now disabled so that if BIOS enables interrupts, there is no crash (well, this will be of course changed in a DPMI host or any other implementation of LFB emulation based on my code). -- Alexei A.
