This was _extremely_ rare and either needed very specific hardware or software. I stand by what I said: so rare as to effectively be impossible to do in the 21st century when both the hardware and the software are very rare > How about EDR-DOS? :-) EDR-DOS is the kernel of SvarDOS. On its own it's just a kernel and little use. And it's the kernel from DR-DOS 7.01 with many enhancements. Built for a 486 with memory management. Not a good choice for a '186 or an emulator. I meant what I said, I stand by it, and it's based on coming up on 40 years of specialist expert knowledge. -- Liam Proven ~ Profile: https://about.me/liamproven ~ LinkedIn/X/FB: lproven Email: lpro...@cix.co.uk ~ Google: lpro...@gmail.com IoM: (+44) 7624 227612: UK: (+44) 7939-087884 Czech [+ WhatsApp/Telegram/Signal]: (+420) 702-829-053 _______________________________________________ Freedos-user mailing list Freedos-user@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/freedos-user
