Solaris is on a 300MB partition, and I would gues that there isn't much space free. Everything seemed to go as expected for the first 15-20 mins until the file /dev/fd0/0 was encountered. I checked the tape on another machine and everything was fine up to this file, but there were several hundred occurences of it.

OS/2 was built from scratch in attempt to be able to meet future requirements. Much of the design philosophy would have been taken from Unix and possibly MVS. I don't see DOS as any sort of model for OS/2. YK> It is a descendent of DOS, it owes nothing to Unix, OS/2 is in no way a descendent of DOS, but was designed to run on the same Intel-based architecture.

Memory management Multi-tasking Process management Long filenames Paging Use of '1>nul 2>&1' constructs in command lines File dates including creation, last access, last write. Wildcard '*' will include all files. ...I could go on, but I think this proves my point.

Windows is a graphical interface, and DOS is a pre-requisite before Windows will load (unless you are running under OS/2). NT will run some OS/2 programs, but Windows won't run any.

Any Sun mavens want to comment? Interesting comments... My Internet provider, Demon, is also heavily SUN based, and they always seem to be having one failure after another, often with hard disks. This seems quite staggering really, since most of their equipment can't be more than a couple of years old. I used to work with mainframes supporting thousands of users and the systems would sometimes run for a whole year (24hrs a day) without any apparent failures.

Any Sun mavens want to comment? Depends on the Sun. If it's something they no longer manufacture then it may explain the problem. Try to find spare parts for some workstations that are a few generations old. Parts first and second generation Sparcs, Sun 3's and Sun 386/486 are damned near impossible to find. Sun doesn't stock anything in their Logistics Division for the older workstations anymore. Finding a SunOS master disk set or tape for a 386i is impossible. Sun's tech support has gone down hill since their corporate reorganization. In my short career (2 year) of working for a Sun VAR as senior support engineer prior to my layoff and moving here to Las Vegas, I have never had a problem with a Sun other than one that was DOA from the factory which I attribute more to FedEx than to Sun. Of course, shortly after my layoff was when Sun did its radical corporate reorganization, bought ISC out and was starting to sell through distributors. About the only thing Sun has going for it is the Webserver and internet provider which SGI strongly competes for. About the only other niche Sun falls into is using their rack mounts for super computer I/O servers. JCA ...
