Just make sure that this thread isn't used for development for staging (they have their own site) but not official dosbox and we will be good otherwise I'll have to close it. my current target is a DOS TSR that inhibits internal UniVBE load - so all dosbox(es) will benefit Also now there are two …

@Zup - the above code replicates exact the detection code in UNIVBE.EXE 5.3a (6.5 and 6.7 seems to use the same) - i've disassembled UNIVBE io just stucked with the VESA code that was primarily needed

added your findings to my example and also made my STATIC_ASSERT into a real static assert :) and added the UniVBE detection (equal to the UniVBE implementation) thanks for the help // build with Borland C++ 3.1: BCC.EXE -mc vesatc.c // BEWARE: needs to be build with a FAR-Data-Pointer memory model …

@DosFreak This isn't a forum for dosbox-staging so if you intend for a patch for dosbox-staging then best to discuss this over there. If the intent is for a patch for dosbox-svn then it can be discussed here. i started the discussion with dosbox-staging developers but i also use Dosbox-SVN and …

Since I do not have Borland C++ I have tried your code with Turbo C 2.01. With some minor modifications I could compile it and in compact/large/huge memory models it gave me correct results. So it seems in order VESA functions to work you have to use a memory model that supports multiple data …

a "char far*" in Memory Model: Small IS a Segment:Offset Pointer - there is no "linear" Address available in Realmode splitting the "char far*" into a struct with segment and offset and combining that with MK_FP gives the same string results // Borland C++ 3.1 // build: path=C:\BORLANDC\BIN // bcc - …

https://anttipeltola.eu/misc/vbe2 ...VBE services may be called directly from 32-bit protected mode only. it seems that VBE functions can only be called from protected mode - is that correct?

https://github.com/liballeg/allegro5/blob/4.2 … ests/vesainfo.c works but that uses DPMI and i want a non-protected mode version could it be that my "Small Memory Model" Borland C code is a problem here?

so i think i understand how it is done and started to develop a small VESA info utility that should also detect UniVBE in the end im using VESA BIOS int 10h/4F00h https://github.com/cirosantilli/ralf-brown-interrupt-list/blob/fde1a5ac1b7e8a45ff4255ee275ee77c7fe7e256/inter61a/INTERRUP.A#L5031 but i …

PS: Did I mention that I'm still thinking of CVS builds ? I know they switched to SVN years ago, but I always forget. Now, that "new" SVN is old itself, as well. People use Git now, or so I heard. Ah, how time flies! :sweatdrop: staging uses Git - SVN is already deprecated (but still fostered) for …

So you can either use your real MT-32 or install an emulator (Munt). Or use an unofficial DOSBox that has Munt built-in and internally connected (old Daum builds come to mind) . or the less old but vibrant dosbox staging which also got Munt built in

From what I have observed, the .DLL doesn't seem to have any 'Activision built' extra function in it. All the functions look to me to be the original ones provided by RAD, even the release date of 3.03d of 'WAIL32.DLL' is the same as the one provided with the application. equal means - every …
