When I run dosemu I get these error messages: LOWRAM mmap: Invalid argument Segmentation fault I have already done this as root -- recommended as the solution for this problem -- but it doesn't help: echo 0 > /proc/sys/vm/mmap_min_addr and "cat /proc/sys/vm/mmap_min_addr" now prints 0 (I think it was originally something like 65536). The dosemu version is 1.4.0.1, installed from an OpenSuse rpm. I'm running OpenSuse Linux 11.2, kernel 2.6.31.12-0.1-desktop, which is a 32-bit system. I get those error messages whether I run dosemu in an xterm or a Linux text console. My CPU is an AMD Athlon XP 2800+ dual-core 64 bit. This is my first time running dosemu. Here's my boot.log: CONF: config variable parser_version_3 set CONF: config variable c_system set CONF: Parsing built-in dosemu.conf file.
