Are add-ons available for the PC/AT version of MINIX that allow the any of the
following:
1. Use all available memory (not just 512K or 640K)?
2. Use the 80386 protected mode?
3. Permit a choice of operating system at boot time (DOS or MINIX)?
3a. How about a DOS & BIOS emulator that runs under MINIX (something similar
to the DOS-Merge available for Sun/OS)?
Any comments would be appreciated. Thanks

If you have Bruce Evans' protected mode extensions. You have to get those from a Minix archive site. >2. Use the 80386 protected mode? Again, Bruce Evans has done it again with a 386 protected mode extension. I will probably be setting aside a Minix partition after I get a bigger hard drive. >3. Permit a choice of operating system at boot time (DOS or MINIX)? I think somebody has made a boot program that is similiar to the Xenix boot routine where you can either boot Minix or DOS. >3a. How about a DOS & BIOS emulator that runs under MINIX (something similar > to the DOS-Merge available for Sun/OS)? There's a lot more to it than emulating the BIOS. You need an application that puts the 386 in Virtual '86 mode and interfaces with the *nix kernel. I don't see anybody wanting to go out and actually writing an application forr Minix that is comparable to Sun DOSWindows, ISC VP/ix, or LCC DOS/Merge. For one, there's the royalty issue of MicroSoft wanting to dip into it. // JCA /* **--------------------------------------------------------------------------* ** Flames : /dev/null | Small memory model only for ** ARPANET : crash!pnet01!jca@nosc.mil | Unix?
