Then please remove it completely (from the code and from the help screen). I had thought that LOG could help with debugging, and I think other people could fall in the same hole unless LOG is removed... > >EMM386 EMM=1416 causes a crash while letting the AuGoS computer > >Go game play against itself.

My full test results were: emm=1408 (0x5e0k EMS) work emm=1024 work emm=256 work emm=4096 reboots while playing Go emm=32640 reboots while playing Go emm=1416 / emm=1424: both 0x600k EMS, both hang while playing Go emm=1440 (0x620k EMS) hang while playing Go emm=1520 (0x660k EMS) / emm=1536 / emm=2048: all crash while playing Go, in all three cases first showing an illegal instruction and then stopping because the MCB at the end of the UMB area, for me at dfdf:0, got overwritten. Or maybe some EMS page got double-used as EMS and UMB at the same time, no idea. In either case, the PC stops. Register dumps for the illegal instruction thing: f000:fffd 0644:fff7 0000 c00b 306, 3c9, 84a, 26f2, 110, 84a, f0e5 f000:fec4 0644:01fe 0000 02c7 823, f07c, 0, 2c7, e52, f0a8, f0aa f000:00d1 2201:171b 0000 3012 fffe, 5800, 57ad, 597, 8, 443, fefe CS:IP SS:SP DS ES eax, ebx, ecx, edx, esi, edi, ebp The MCB got overwritten with 3 similar and 1 other dwords in each case: 2f 09 8c 11 2f 09 6c 11 2f 09 4d 4d 02 00 9c 11 37 07 cc 00 37 08 ac 00 37 07 4d 4d 02 00 dc 00 ... hm, I think in the f000:00d1 crash the PC hung before the MCB dump.
