So I've been able to free up a larger block of UMB (143k) by adding "I=B000-B7FF I=BC00-BFFF I=C800-EFFF" to jemmex. However, fps fb pro 95 still finds 0k of the 8mb free ems. -L On Tue, Sep 18, 2012 at 12:21 PM, Rugxulo > wrote: > Hi, > > On Tue, Sep 18, 2012 at 12:39 PM, Ralf A. Quint > > wro

There's only 13K upper mem free according to mem/c. I believe it is in one block. And, iirc, all that most apps need is to be able to swap a 4k page at a time. My guess is that jemmex doesn't implement ems in a way that fps fbpro expects which is why it finds 0k free ems. I'm using the same defaul

Are you absolutely sure there are no errors when when you are installing the EMM? What screen messages do you get when it is loading? I'm guessing what may be happening is that you have enough poorly placed (virtual) hardware ROM modules that the EMM can't find a contiguous 64k block of upper

1GB sounds really big. I remember some games had troubles detecting memory above a certain amount, due to some kind of overflowing in their mem counters. I'd suggest trying to set a more classic amount of ram on your vbox machine... Like 64MB or so. Mateusz / Mobile mail / Louis Santillan w

Hi all, I'm having trouble running an old favorite DOS game that requires EMS inside of VirtualBox (Sierra Front Page Sports Football Pro 95). The game requires 576K Conventional RAM, and 2MB EMS. I've configured VirtualBox to have 1GB and installed FPS FB Pro 95 to a 32GB FAT32 drive with FreeD
