Re: CMOS memory size mismatch

okay, good to know .. I tried to set extended ram to 0 and base ram to 512 / 640 kB, but bios complains .. the only working setup - didnt test more than 1 MB - is setting ram to 512k in both pcem config & bios base memory so far, of course only suitable if 512k are enough for you ..

Gfx tearing

I'm using a internal VSync-wait for my prods to avoid tearing when updating the gfx memory and it's working in DOSBox & real hardware .. when running PCem I see more or less heavy tearing between the frames (emulating i286/16 on i3 / i5, runs at full speed) .. even with the latest mainline. It doesn...

one suggestion - would be nice to have some fixed screen resolutions for window .. you could either stay with fixed & scale, but in that case the window is resized everytime the resolution of the machine changes, or it stays the same window size when set to resizeable, but it's only freehand .. so g...

oh, sorry, maybe my fault .. atm only my code, I initialized the mode like Michael Abrash did, in Dosbox it went fine .. I'll check it again and tell you if I find the bug, perhaps PCems emulation is simply more realistic than dosbox and doesn't forgive coders inaccuracies !
