-
- | What is the main differences between SCO XENIX and SCO UNIX?
-
- UNIX has the extended filesystem with long filenames and symbolic links.
- It also resists fragmentation /far/ better than xenix. Xenix take a lot
- less disk to run (6MB or so) in the minimal case, and less memory (we
- run in 2MB on laptops). Xenix has no NFS.
- |
- | Could binary programs for SCO XENIX run under SCO UNIX?
-
- Virtually all will.
- |
- | How much disk is required for the UNIX system compared to XENIX?
-
- See above, figure about 10MB more for UNIX.
- |
- | Is it possible to connect any SCSI tape drive, DAT, Exabyte, QIC150 etc
- | to the XENIX and UNIX system or does each require a new driver?
-
- These work off UNIX, and in general SCSI tapes run on Xenix. There is a
- funny in some Exabyte drive firmware, I think the 5GB version, which
- requires using new tapes on SCO.
- |
- | Is it possible to boot the system from a SCSI disk?
-
- Yes, but you can't mix SCSI and ESDI/MFM/RLL/IDE and still boot off the
- SCSI. Actually you can, but you don't remotely want to know what it
- takes ;-)
- |
- | Is it possible to do any development without the Development package,
- | like cross compiling on another computer with GCC?
-
- If you have another system you can compile on that. But you can't just
- drop in gcc and run, although that may be possible by the end of the
- year. The new SCO C beats gcc for many things, and includes codeview
- (and cross compile to Xenix, OS/2 and DOS, if you care). If you just
- need a high quality C compiler, gcc does a fine job.
- |
- | Is there any text editor included in the XENIX system?
-
- Not in my opinion, but ed and vi come with it. You can get three flavors
- of small EMACS or the huge "real thing" if you want.
- |
- | Will any 486 machine run SCO XENIX?
-
- No, some vendors have managed to mess up their motherboards so the
- external cache doesn't work to Intel timing standards. But about 95% of
- all systems will, and (as far as I know) all major brands.
