Except for graphics, the program runs fine (don't crash) in xterm console (dosemu) with the standard configuration. When run with xdosemu, I get the graphical splash screen then dosemu crashes with the following error : ERROR: Fault in dosemu code, in_dpmi=1 ERROR: BUG: dosemu touched the protected video memory!!! ERROR: cpu exception in dosemu code outside of DPMI client! trapno: 0x0e errorcode: 0x00000006 cr2: 0x000a0000 eip: 0x08093c11 esp: 0xbffff6b0 eflags: 0x00000206 cs: 0x0073 ds: 0x007b es: 0x007b ss: 0x007b Page fault: write instruction to linear address: 0x000a0000 CPU was in user mode Exception was caused by non-available page ERROR: leavedos() called from within a signal context! Is this fixable with dosemu.conf ? It have read about old Phar Lab . The string "Phar Lab" is in the program (not in the graphics TSR library): > Copyright (C) 1986-92 Phar Lap Software, Inc. > Copyright (C) 1988-91 Phar Lap Software, Inc. > Phar Lap 286|DOS-Extender present > Phar Lap 386|DOS-Extender present But I wonder if that could be the problem. I have tried to run it in console mode as root but I don't know how to configure my vga card in dosemu.conf I get a black screen if $_graphics = (1) Thanks, Julien
