        Is there a list of current Linux projects (like WINE)?  Also,
how would one go about joining such a project?  Thanks in advance.

Subject: Ux4F: multiple commands completed (UltraStor 34F)
Date: Thu, 26 May 1994 04:07:56 GMT

I (now) have a 486 DX2/66 with an Ultrastor 34F controller and two Quantum
1.8GB SCSI drives.  I just installed the second Quantum, together with 
20mb of RAM (from 8mb).

The new drive is assigned to be my alt.* news partition.  I am currently
in the process of copying stuff from my old alt directory to the new disk.
All seems to be working perfectly except for  some really odd messages that
pop up occasionally:

   Ux4F: multiple commands completed

I have traced this to a specific line in the Ultrastor driver code, but
can't figure out what it means.  The implication seems to be that it's
managed to do more than one thing at once, but when a message suddenly
prints on all my active virtual consoles, I tend to think the news is
bad. 

Anyone have the real story behind this message?

Also, I have a relatively old source tree - I think it's from 99.15.  Has
anyone done more work on this driver that would make it run better?  It's
not really bad, but I remember hearing something about this ... does anyone
have actual infromation?

Thanks!

Well, if that's what he said, I tend to disagree with it.  :)  If your
design spec says "this program will only run on POSIX-compliant platforms",
why, you've made a limiting design decision.  One that may help you to
maintain your software better.  If you so publish in the documentation, this
doesn't reflect badly on your programming skills in the least....

If you don't publish that fact, I'd say you have real problems in designing
and documenting an application.  They're correctable, though.  :)

I run a 445S with BSDI and the beta driver from them, and it is a SMOKING
fast board.  Really nice, it works, and I haven't seen ANY problems with it
whatsoever.  Other than crappy cables (which will screw you immediately as
the board is a SCSI-II FAST implementation) and disks which died on their 
own (unrelated to the adapter).

Highly recommended.  I love mine, and will buy more.  My primary news
server here runs one.  No complaints.

I personally like exmh.  It's a X front end to MH that works really
well and has a built in MIME editor.  It'll automatically deal with
MIME messages, displaying text in multiple fonts, etc.  It'll play
audio messages, too.  You can get it from parcftp.xerox.com, in
/pub/exmh.  You'll need tk and tcl, they're somewhere on sunsite,
along with MH, it's on sunsite too.  If you can't find anything, send
me mail and I'll try to give better pointers.

SIGIO was just added in the most recent versions of Linux (1.1.13 was

new tty subsystem that allows and enables SIGIO) has released a patch

Because this starts me wonder which kernel I should use with my 445S REV D

But I'm waiting for the 3.37 Eprom to go to 32MB. Should I use the BT

Thanx in advance for getting things cleared,

Nothing went wrong with the patch, but putting the old drivers in 1.1.15
works..

The new code finds the Adaptec, find my first SCSI disk, and before
finding the second one stops with the quoted error message.

Reading the code shows that the machine should continue to boot anyway;
since I have 2 IDE drives and I boot on one of them. But it does not.

Anyway, since there are problems with this 386 and nfsd as of 1.1.13, 
I think I'll keep 1.1.12 + new tty drivers on this Linux box for the 
rest of its life :-)

(And hide the version number since it is a public access Linux...)

           - ability to remove packages

           - ability to specify arbitrary scripts to be run before and/or after

             ability of these scripts to compute new files to be installed as
             part of the current package

I agree with all of these requirements, particulally the ones about
ability to remove packages and the database.

   I expect that inside of 10 years we'll see widespread standardization on one
   or more relatively general-purpose packaging standards. I doubt it'll happen
   in 5; it takes people longer than that to learn why it's needed.

I think this is the problem.  There are only a few people who are
*using* their Linux boxes in situations where they cannot be
re-installed if required.  THIS ISN'T FLAME BAIT.  Yes, I know that
there ARE people who are doing real jobs, but for the most part people
who are using Linux are committed to the "cause".  They're quite
prepared to take the hit of a re-installation - How long does it take?
Perhaps an evening, perhaps two.  That equates to one to two work
days.  I guess I should clarify using to mean administering before
lots of people start saying things like 'well, I've got 75 users and
they're all dead happy'.  I personally prefer to live with out of date
packages unless I need the new functionality just because I need
something that isn't a moving base in order to do my job.

I honestly believe that if Linux is going to do well outside of the
environment where people are prepared to put the work in (i.e. if it
is going to be liked by overworked sysadmins) then these are the sort
of tools that will be needed.  Of course, there is no point in having
the tools if people aren't going to use them - an earlier poster on
this thread said that they'd produced a set of tools because of
exactly these problems, released it to the net and then had very
little feedback.

I hope someone is archiving this - I'd like to be able to come back in
three years and say "I told you so...."

Of course does linux support the Turbo Pro, but what I think you really 
want to know is whether XFree86 supports the Mach64, don't you?

Up to now ATI did not give the documentation for the Mach64 without
non-dispclosure agreement, which is a no-no for free software. So 
up to now XFree86 does not support Mach64 based cards and it will 
probably not in the nearest future. Once ATI provides the information,
support will be worked upon.

Hello there,

We are planning to buy a Compaq Deskpro XL 5/66. This is a computer with

Qvision 2000 video controller.

I would really like to use LINUX on that machine but I don't know if 
LINUX supports this configuration.
Can somebody give me some information about this. 

Does Linux work on a fast SCSI-2? 
Are drivers needed/available for the Qvision 2000 video controller? 
Does linux support the PCI bus?

Can anybody give me advise?

Subject: PROBLEM: bad serial I/O
Date: Fri, 27 May 1994 01:24:22 GMT


I have been having a small problem since upgrading to 1.1.11.  Today I
went to 1.1.15, same problem.

Basically, serial I/O is really bad now.  Transfering files I get lot's
of CRC errors and when using software online I get scrambled screens,
etc.

It seems to happen whenever there is disk I/O.  Like I'll just be
looking at the screen and the disk will access and a tiny burst of ascii
garbage appears onscreen.  It doesn't seem to go to the remote system
them because a redraw shows the garbage characters were not input to the
remote machine.

This is even happened once to an xterm and even a console locally with
no serial I/O.  There was a drive access and some garbage appeared
onscreen.

But the first problem I noticed was the CRC errors in zmodem file
transfers.  It's the most easily reproducable.  

I never added the tty patches... until my SCSI tape drive is
working it's one too many projects at once... unless it happens
to be a sure-fire solution.

I am having problems getting a Future Domain TMC-950 SCSI controller
working with my tape drive.  Could that be causing me grief somehow?  It
was installed near the same time I upgraded my kernel.

Anyway, I've been seeing a lot of discussions about similar problems and
thought maybe this might be related.

Oh, I *think* that the problem is reduced in 1.1.15... after some more
testing I'll try to report more thoroughly.

Finally, sendmail refused to work when since going to 1.1.15.  Any ideas?

If this sounds far too bizarre I'm willing to do a 'level 1 diagnostic'
but I wanted to get some ideas first.

If my tape drive were only working... grrrrrr.
