The first lesson for everyone is to be a more demanding buyer. Get a
guarantee that the computer will run Linux or you can return it for a
full refund. To be fair to the dealer, you should be required to do
the testing within 10 days. However, you don't have that and you need
Make sure your Linux RAM disk works on another computer. You can load
the BOOT & RAM disk without proceeding with the installation. You
should be able to use just about anyone's computer. I'm assuming you
are using a stable Linux, like Slackware 3.0.
If you are sure that your masters are OK and you know how to load
Linux and Solaris, then I'd be back to your dealer.
There is no good reason that a working and properly engineered
computer that is based on the Pentium Pro should not run Linux or
Solaris. "Pentium Pro" implies "IBM PC 386" compatibility. This
computer (assuming you are loading correctly) is *NOT* compatible as
Aside: Was Windows NT one of the operating systems tested?
The dealer may not know that Linux works. May never had heard of it.
May not have heard of Solaris either. Linux is an operating system
that is known to work (assuming you are using a good version).
Solaris is a COMMERCIAL operating system! It is also well tested.
That a PC compatible (386+) computer is fine but won't run Solaris is
a patently ridiculous statement.
What's happening here is that Linux & Solaris are asking the computer
to perform a task that it is *supposed* to be able to perform.
Windows doesn't ask the computer to perform that particular task (or
not that fast or whatever) and thus the computer doesn't fail.
Let's say you went down and purchased a car. Worked great until you
used 4th gear. You take it back to the dealer. "Sorry, but we only
test our cars up to 30mph." You would then agree that the car works
fine up to 30mph. But that hardly proves the car is working.
I think the dealer either (1) doesn't care and is trying to get rid of
you or (2) doesn't understand the problem and thinks it's software or
I have lots of stories, but I'll pick a one. Linux loaded. DOS 6.22
was already loaded. Win3.11 worked fine. But Linux would crash after
5 minutes. The crashes also caused file system damage (ouch).
Finally, after booting DOS 20 times, the HIMEM.SYS memory checker
found defective RAM. DOS failed again after another 15 boots. The
RAM was replaced and the computer has been happily running Linux for 6
The lesson is that a computer can look OK in one or more operating
systems. But that in no way proves that the computer works.
The same goes for so called "diagnostics." Diagnostics can only prove
that a computer is broken. Diagnostics cannot prove that a computer
is working. Perhaps the best diagnostic for a computer is a
multi-user operating system.
I don't know if this will help, but feel free to take this down to the
