Dynamic recompiler and UNIX

Post by ArtiomWin »

PCem has an issue with dynamic recompiler: it refused to run installation programs of UNIX-based systems which means no UNIX installation on emulated Pentium systems.

Please provide details of both host and emulator configuration.

I suspect this is your feature messing with operation, because to quote from another place:
ArtiomWin wrote:SCO UNIX with dynamic recompiler turned on - it (binary) gives error "Deleting deleted block" and closes down.
I suspect it uses a jump to 0:0 to do something and fatals the emulator because of that when using the recompiler. It also happes when the Rhapsody DR's.

Many non-Microsoft operating systems have major issues with PCem (and 86Box), most
particularly on processors where Dyna is enabled. In most cases, turning off Dyna will
fix that (at a speed cost, of course.)

Confirmed for AT&T SysV R4.2, ESIX, 386/ix, Interactive (which is the successor to 386/ix)
and several Linux-based systems.
