There is no kernel that comes with 1.1.3.2 - it's just a development test version of DOSEMU. In general DOSEMU is FreeDOS kernel agnostic - though newer kernels tend to work better than older ones. > > Oscar > > Hmmm...does that mean I should be using Freedos and not DRDOS if I want > proper kernel locking? I hope Foxpro works well with Freedos! FreeDOS should work just like DR-DOS in this respect but it never hurts to try FreeDOS. In general DOS talks to DOSEMU lredir'ed drive through the redirector interface. This is a list of calls you can find in Ralf Brown's Interrupt List at INT2F/AX=11xx. It's a horrible interface because it wasn't designed as such - but we have to live with it to get proprietary DOSes to access lredir'ed drives. The same redirector interface is what DOS uses to talk to network drives in general and with MSCDEX/(FD/SHSUCDEX)/NWCDEX for CDROM drives too. FreeDOS kernels before ~2026 did not translate --------D-215C------------------------------- INT 21 - DOS 3.0+ - "FLOCK" - RECORD LOCKING into --------N-2F110A----------------------------- INT 2F CU - NETWORK REDIRECTOR (DOS 4.0+) - LOCK/UNLOCK REGION OF FILE That was the problem - the redirector interface is a relatively recent addition to FreeDOS. DR-DOS should not have this bug. I suspect that the way that DOSEMU tries to implement DOS locking techniques is not compatible with mandatory locking on the Samba Unix side.
