Subject: Re: Switching between Linux and another OS without rebooting???
Date: Mon, 18 Jan 1999 14:16:03 -0800
Short answer: No.
You need the ability to checkpoint the entire executable operation
of multiple opreating systems, their hardware and software states, and
the
ability to restore a saved executable state of an OS and its processes.
IBM mainframes running VM (Virtual Machine) can have several operating
systems
coexist, giving the user the ability to switch between operating
systems.
Switching operating systems is a much bigger hastle than switching
processes
or applications within a single operating system. The ability to share
information between operating systems is controlled by the underlying
virtual
machine architecture.
With Intel processors, I know of no such capability unless you specially
design an array of processors and a control program able to task
schedule
operating systems like most multi-task OSes schedule the execution of
programs. The control program should also wrap all system devices in
virtual device code that can be dispatched to the various operating
systems.
OS emulation is another possibility, but here you get away from vendor
operating system code and into a proprietary emulation that needs to be
separately maintained. OS emulations are not normally supported by
the designers of the "true" operating system.

If English is your native language (and it is mine) please set a good
example and use it properly in these groups. I don't want to start a
flamewar but the people who don't speak English as their first language tend
to write better English than you.
People like you annoy me as they tend to give British and American people
the image of being arrogant and unhelpful. It is useful to brush up on your
English language ocasionally, and no-one is saying that you have to read
Shakespeare. I certainly don't.
Anyway gotta go..

You might also try writing RPCs and including calls in your client code.
The RPC procedures execute on remote systems across a network.

Our network environment is built against various UNIX'es from SPARC SunOS,
x86 SunOS, SPARC Linux, and x86 Linux. For us it really came down to 1)
naming service 2) hardware compatibility.
If your network really _needs_ the "secure" features of NIS+ - then SunOS
for x86 is probably your best bet. However, if you can settle for plain ol'
NIS (yp) then Linux will do the job - quite nicely in fact. The main
problem with SunOS for x86 is the lack of hardware support. Many devices
(especially graphic cards) are hard to support because Sun is slow to
actually do the work of porting a driver based on specs to SunOS.
SunOS for x86 is a nice operating system - nice, fast kernel. But - with
Linux's constant support from the community of free unix users, you'll be
hard to find up-to-date security patches for SunOS for x86.
Any specific questions - feel free to ask.

All I have in /lib/modules/2.0.35/misc is sound.o But that's all I got when

I have served as an expert witness in the past for Microsoft and for others
and can report that Microsoft does indeed coach you in writing your opinion.
They are much more agressive in that regard than other's I have worked with.
Schmalensee is the author by virtue of his signature but he is in an awfull
situation that is probably career limiting. However, when you are an author
for Microsoft you are required to sign agreements that limit your career anyway.
So I do not feel bad for him. His testimony was a flop for Microsoft because he
based arguments on surveys that were contrived by Bill Gates. This is part of
the coaching process. Microsoft provides its authors with lots of material, at
least that was my experience. Schmalensee was in many regards set up. He
probably knew that but proceded anyway. He probably never invisioned the
thing going to court. It should not have.
The court views OS/2 as a Microsoft product owing to its history so the only
potential competitor to Microsoft OS's on the desktop appears to be Linux.
Schmalensee is testifying in other cases for Microsoft and I believe he had
to be cautious about what he said in this one which, by all indications, Microsoft
has lost already.

I have a Crystal CS4231A-based sound card which I am trying to configure
using loadable modules. I have tried to load all the modules as
described in the sound documentation
(/usr/src/linux-2.0.36/Documentation/sound/CS4232).
The modules install up to the last one:
[root@riemann /root]# modprobe sound

[root@riemann /root]# insmod cs4232 io=220 irq=5 dma=1
/lib/modules/2.0.36/misc/cs4232.o: init_module: Device or resource busy
I have checked /proc/(interrupts,ioports,dma) and there do not appear to
be any conflicts there. Also, I have tried loading the SoundBlaster
drivers and get the same error message when loading the last module(sb).
Has anyone else had this problem or know how to fix it?

You don't want `root' in there. On my system, at least, anything in
/etc/crontab will run as root automatically; if you want to run it as

Subject: Fastrack [raid?] controller & related Q's
Date: 18 Jan 1999 19:33:00 GMT
This is more of a hardware query, but I'm also interested in the software
side as well, so to both groups this question goes:
[background] I'm working on a project involving Non-Linear Editing (NLE) of
video tapes, as such I'm looking into newsgroups related to that topic and
I find LOTS of praise for the PROMISE "FASTRACK" PCI udma controller. This
looks like it does some raid0 & 1 functions [multiple/striped disks, disk
mirroring] [re: see various threads in REC.VIDEO.DESKTOP]
[the question(s)]
1) WHO has successfully used the FASTRACK in a linux environment and are
you willing to share your experiences? [BTW: I hate the "open ended"
version of this question "has ANYONE ...", of course, SOMEONE probably HAS
had success, they just aren't reading this newsgroup ;) ]
1b) Although nobody has mentioned it on the other newsgroup(s), another
controller I've seen is the Adaptec 333 [I think] which is SPECIFICALLY
raid-oriented [and may even require a special MB], again, anyone willing to
share success/horror stories of getting it to work with Linux?
1c) [not that I'm expecting much of an answer at this point...] I've
also seen another raid-specific SCSI controller at Fry's, but cannot think
of the name of it offhand...
2) I know there are various implementation levels of RAID [0,1,3, & 5
being the most popular], even talked about them in school, but "it's been
awhile" and my mind is getting foggy on the details :) Specifically, for
raid-STRIPING, which is better/easier: IDE or SCSI? I suspect the FASTRACK
will stripe to one device on each IDE interface first, then both devices on
each device for a total of four devices in the "stripe set"; when dealing
with SCSI, there is only one interface/cable, although each device can
more-or-less run independantly of the processor, so does this affect the
overall capability of the system?

Sorry, I can offer no help, but I did have a similar problem. I have
an old compaq 486 66 and it bahved the same way as you described. I
was running RedHat 5.0 It refused to recognize my printer port about
half the time so I finally just decided to le the thing run all the
time. It is Linux after all, and you really don't need to shut it
down. I just figured it was crappy hardware by Compaq that was causing
it.

I would personally like to see more documentation for the average weekend
Linux hack to be able to put together a Linux cluster first. I have yet to
find a good how-to in the Borders or Barnes & Nobles which I visit.
Beowulf from what I can find is okay in the sense that it provides a way to
"loosely" couple distributed systems through a message passing mechanism.
This is still a long ways ready for the business environment or even
end-users like us. How many or what types of problems are you trying to
solve using parallelism? Another issue which is still plaguing the Windoze
world is making applications cluster aware and allowing recoveries across
nodes. Last I recall from the 80s, managing a production cluster is no
easy task.
What I would like to see next is a way for a single node in the Beowulf
cluster to act as the disk controller for all the nodes in a method which
is programmatically transparent - similar to an HSC/Star Coupler with the
Dec machines. I understand that this is the topic of many research
projects today as a way of trying to solve the I/O performance issue. Oh
well, maybe when the solve it and wait 5 years, the hardware will be
affordable!
