You need svgalib not for the resolution, but for the ability to do graphics on a text console. Before you build anything I recommend doing 2 things... 1) putting "-svga" in USE in /etc/make.conf svga has to pound away directly at I/O ports in order to do graphics in a text console. This requires root-level permissions. So dosemu will need to run either setuid or setgid. If you put "svga" in your main USE variable, you'll find *A LOT* of stuff will eventually be linked to the svga libs and it will all need to run either setuid or setgid 2) putting the line... app-emulation/dosemu svga ...in /etc/portage/package.use so that only dosemu links to the svga libs and needs to run setuid/setgid. Note that you should really be running dosemu *FROM A TEXT CONSOLE* in order to emulate running in DOS on a 486SX. An optional flag is "gpm", which links in support for using the mouse on a text console. Does your program, or any other program you run in dosemu, require mouse support? Plan B) If all else fails, enter the line... games-emulation/dosbox svga ...in /etc/portage/package.use and remember "-svga" in USE. Then "emerge --ask dosbox". Same notes about svga apply here. dosbox is damn good for DOS emulation. I've run QBASIC, and dBASE IV complete with DOS-4GW memory extender under dosbox, as well as a bunch of *REALLY* old DOS games. What takes the cake is that I was actually able to install Windows 3.1 in dosbox, just like the "good-ole-days" when you installed Windows over DOS. This was to run an ancient Chessmaster 3000 game. It runs under either Win3.1 or Win95, but I never could get it working under WINE. Under Windows 3.1 on dosbox, the emulation is perfect, and Chessmaster 3000 whips me mercilessly, just like before. -- Walter Dnes <waltd...@waltdnes.org>
