CVS contains 1.6 (or is it 1.7? MEM_MINOR contains 7). JvR I believe the crash is caused by a bug in the 386-detection code JvR inside MEM.EXE. The detection always gives false positive results JvR on 8086 systems, leading MEM.EXE to execute a subroutine which JvR contains 386-specific instructions. JvR The 386-detection code basically tests whether it can set flag bits 12-14. JvR On a 8086 however, bits 12-15 are always set. It may be possible to fix Yes, looks like you right: I check MEM 1.6 (1.7?) and found, that its 386 detection code is buggy, because tries to set 0x7000 in flags and expects, that both bits will be set only in 386+ (whereas bits 12-15 always set in 8086/80186; in 80286 bits 12-14 are IOPL and NT and always cleared in real mode). Right code should be (excerpt from my MEMA): /* try to change bits 12-15 (0xF000) in the FLAGS register... */ I pushf; I pushf; I pop ax; _AH ^= 0xF0; I push ax; I popf; I pushf; I pop bx; I popf; /* ...then check whether any bit was changed */ count type = 3; if (_AH ^ _BH) return type; type = 2; if (_BH 0xF0) type = 0; return type; - Using Tomcat but need to do more?

Base list still shows: MEM 1.7 Bart Oldeman Jim should decide wether to take the 1.9 from that other side. Was it ever contributed? Maybe the author should be contacted.
