You need svgalib not for the resolution, but for the ability to do graphics on 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

Hello Walter, Your response is much appreciated (see notes below).

The target device has limited storage and doesn't have X. For sure, the goal is command line; _no_ X. Running on the application on the target just gives a black screen, so I needed to see if another environment would give a different result. Also, I was using a pre-built binary of dosemu and don't know what options it was built with. FWIW, my 32-bit gentoo system has an AMD Geode LX graphics chip and DOSEMU complains of access to port 0xAC1C which is part of the linux kernel's geode drive which is defined in asm/geode.h as #define VSA_VRC_INDEX 0xAC1C Does DOSEMU have any expectations of a kernel built with a generic VGA driver?
