The above EIP falls in the routine schedule(), as the following values
from zSystem indicate:

    0010cda4 T _schedule
    0010cf94 T _sys_pause

Solution:
    The short version - Go into BIOS setup, go to CHIPSET FEATURES
    SETUP menu, and set the "Hidden Refresh" option to "Enable".

    The long version:

    Thanks to a hint from Eric Boerner <eboerner@sdcc3.UCSD.EDU>, I
    started fiddling with BIOS parameters.  I changed many individual
    features, but without luck.  I noticed that the main BIOS setup
    menu had a "LOAD BIOS DEFAULTS" entry, and a "LOAD SETUP DEFAULTS"
    entry.  The settings I started with (as set when I bought the PC)
    were pretty close to the "BIOS DEFAULTS".  When I loaded the
    "SETUP DEFAULTS", I noticed three values change:

    - In the BIOS FEATURES SETUP menu, the "Gate A20 Option" option
      changed from "Normal" to "Fast".

    - In the "CHIPSET FEATURES SETUP" menu, the "Hidden Refresh"
      option changed from "Disable" to "Enable".

    - Also in the "CHIPSET FEATURES SETUP" menu, the "External Cache
      WB/WT" option changed from "Write Back" to "Write Thru".

    I narrowed down the problem with the floppy to the "Hidden
    Refresh" option.  If that was set to "Disable", I got kernel
    panics.  If set to "Enable", everything was OK.

    I decided that, because the "Hidden Refresh" = "Enable" came
    from doing a "LOAD SETUP DEFAULTS", and the two other values also
    came from this, that I would go with all three values.  I set up
    all my BIOS parameters by doing a "LOAD SETUP DEFAULTS", then
    disabling the Power Management features.


Thanks to those who helped,
Tim

        Remy Card has done a port of the BSD dump/restore utilities to
the Linux ext2fs.  This is still very much in the ALPHA testing phase,
though I have been able to use it successfully with my SCSI tape drive
and ext2 filesystems.  You can find this package at the URL:

        ftp://ftp.ibp.fr/private/remy/dump/dump-0.1.tar.gz

Note: Do *not* compile dump as a QMAGIC executable.  There is a bug,
which Remy has apparently found, where one of the string functions was
being called with a NULL argument.  The fix is not yet included with
the 0.1 distribution, but everything works fine if linked with -N.

        Again, please note that this is ALPHA test software and may
have bugs.  It also works only for ext2 filesystems.  Use it with care
and report bugs to Remy.  See the docs in the dump tar file for more
information.

        I have no knowledge about ftape, so I can't help you there.

   Why not put both adaptors on the fastest bus possible?

   I know that when I spec hardware, I try to make sure that
everything can get into and out of the system as fast as
possible, even if the devices attached to the adaptors may not be
that fast.  Why?  At a later date, I might want to put something
faster on that adaptor and I'd be really miffed if I had to replace
it with something faster.

  Umm, I think this is a case of ymmv.  I've purchased systems from
Dee One, and from Hi-Tech USA, and not had much problem with them
at all (One system came with a defective floppy drive, which I
replaced) -- the hardware was perfectly reliable, within the
limitations of being the cheapest things on the market, and the
support was adequate for my needs.

  I think you need to be fairly technically competent to be happy
with what you buy from Dee One and Hi-Tech; if you're able to tear
boxes apart for troubleshooting, their support staff can be talked
into sending replacements for the broken parts.

First: upgrade to 2.0.4 as all releases in the 2.0 serie are bugfixes to the previous release. Some reqal basic things are not working with 2.0.3 for some people (trsh and the like). Find 2.0.4 on sunsite.unc.edu:/pub/Linux/Incoming.


Then you maybe lucky and get it installed without pain. Otherwise you have to hack around in the makefile.in and correct some pathes. 

Don't bother messages like mkdir: /tamu/Cr/akc0077/term: File exists : The makefile does not check whether a directory exists or not . It just tries to create it. also don't bother the mv -error messages you got. The makefile tries to save your old term binaries in the directory it wants to install the new ones. Most probably you do not have old binaries in that directory so move fails. Again without any check of existance of files  the mv command is executed, thus presenting this kind of errors.

Sorry but true: the Makefile.in script works (!?!?!) but that's really all!!!!

The current issue of Byte Magazine (Sept. 1994) has a relatively
favorable review of Linux starting on page 167. It is not 100%,
in part due to its brevity, but all in all, very good exposure.
The reviewer based the article on a Fintronics pre-configured
Linux system. Read it. I would be curious as to your reactions.

           Could anyone who has gotten a NCR53c810 (or any other chip in that
   series) based SCSI host adapter to work on a system with an Intel 
   Priemere/PCI II (aka Plato) motherboard please let me know? It is my
   understanding that this should work with a BIOS rev 1.00.8AX1, but I would
   like to confirm that there are real people who have this working.

                                                                   -Craig

I had a NexStor NCR-based PCI SCSI-II controller in my system.  It worked under
1.00.03AX1Z.  However, if you flash to a BIOS of 1.00.04 or greater, you'll
find Intel has included the NCR code in its BIOS.  For me, this caused a BIOS
conflict that made the system lock at boot time.  You'll have to disable the
BIOS on the NexStor board to get it to work under LINUX.  However, this breaks
the DOS and OS/2 drivers for the board.  This means that you have to use the
CAM drivers.  Those are suppose to work OK in DOS, but they fail under OS/2.
My solution was to buy an Adaptec 2940 to boot from and attach a SoundBlaster
16 SCSI in the chain so I could boot LINUX.

You need to check your Xconfig file in $home, /etc, or /usr/X11/bin ( I think )
for your selected mouse.  I have one of the older rounded mice and it took
a combination of putting 'MicroSoft compatible' in the kernel compile and 
"logitech' in the Xconfig to get X to run for me.

Good luck..

It could probably be defended as Fair Use by claiming that it's a
  parody. It works in music. It's quite clearly a take-off on the
  Intel slogan, and I like it as such. It's not like Linux competes
  against Intel. Quite the contrary, it promotes the use of the Intel
  archetecture.

Then again, Intel prolly has lawyers sitting around waiting for 
  something to do. The T-shirt designer would have to hire one (or more) 
  to defend himself, even if he was eventually ruled to be allowed to 
  use the slogan. It'd cost far more than the shirts would ever bring in.

        Justice for money, how much more can you pay?
        We all know it's the American way.

                                Styx 

Personally, I hope Intel never notices.

I've finally broke down and decided to purchase a cdrom drive for my 486.  I'm
