As far as I know there are no documented bugs in the AMD 386.

If there were you would be sure that INTEL would brag about em.

I have run all the tests mentioned and has absolutely no problem
with my motherboard with AMD396-40.

I often use my machine hard and leave it processing for more then a
day.

Maybe the motherboards in question should really be 33 MHZ, and not pushed
so fast, and were not designed with the AMD in mind.

I have heard that the AMD 386 is faster then an INTEL 386 at the
same clock, so maybe the motherboards are depending on the delays in the
INTEL 386 which is a pretty flakey thing to do.  Anyways I am very
happy with my AMD386-40, I recently added a Cyrix 387, nothing
seemed to change except floating point speed.  I.e. 1.0+ Mflops with
the flops.c benchmark.

Just one more datapoint.

I've been having the same problems compiling Lilo and ps-0.97 after
installinf v0.97 and v0.97pl1.  Could someone please post or email me
a description of the correct usr/include structure.

I've tried linking /usr/src/linux/include/linux to /usr/include/linux,
but that doesn't work.  All I get is a lot of redefinition errors
because both sys/types.h and linux/types.h are being included.  I've
also tried linking the sys directory in similar fashion but that
doesn't help either.


Thanks,

Date: Fri, 14 Aug 1992 10:04:01 GMT

Im sure this is a common problem, but.. i have no information
to help me with this..

I am writing a small client to do something, that uses PTYP/TTYP pairs..

The client opens the ttyp open("/dev/ttyp0", O_RDWR) etc etc

and then fdopen's two streams (one for input, one for output)..

well.. anything that is sent to /dev/ptyp0 for some reason
ends up on the client twice!!?!?!

the client only does this as yet..

while(1)
   {
   ch = fgetc(datin)l
   printf("%c", ch);
   }

If in another VT.. I do this echo hello >/dev/ptyp0

I will get

Hello
Hello

I get it twice?!?!

Any ideas..

Thanx in advance

Subject: Small system compile woes
Date: Fri, 14 Aug 1992 13:05:20 GMT

I would appreciate any help on the following two problems.

1)   For the virtual terminals, the linefeed appears to be interpreted
     as only a linefeed, not a carriage return/linefeed pair.  That is, the
     cursor moves to the next line down but stays at the same column
     position.

2)   Defining the root device in /usr/src/linux/Makefile seems not to be
     effective.  That is, build always creates a kernel that looks for
     the root directory on a floppy.  Make prints out the build command
     and the last argument is my root device (/dev/hda3), but build
     seems to ignore it.

Thanks for any help.

        Hello everyone.

        I recently downloaded the TeX stuff from 129.78.66.1 (the Australia
site) and followed the instructions in the README.222 file, and got it
installed.

        I thought that I was about to fly. But when I ran "latex foo" or
"tex foo", I got the following greetings:

================================================
This is TeX, C Version 3.141
I can't find the default format file!
================================================

The first line is fine, but the second line ruined my whole day.

        I looked around the directories and found that all the format files
"xxx.fmt" were there under the "/usr/local/lib/tex/formats" directory.

        So, what did I do wrong? How come TeX didn't like me. :-(

        Could someone please help me out here?

Date: Fri, 14 Aug 1992 16:42:55 GMT


Hooray ! Despite the many postings re glitches, features, bugs, etc.,
both 0.97 boot-image and root-image work;
In addition to boot screen announcements of hd0 etc etc the following
graced my screen
        sd0 @ scsi0 ID0 lun0
        sd1 @ scsi0 ID4 lun0
        sd0 p.1 start    32 size 51168 end 51199
            p.2 start 51200 size 40960 end 92159
        sd1 p.1 start    32 size 20448 end 20479
            p.2 start 20480 size 20480 end 4085?
and so with fear and trembling i interpreted sd1 p.1 as sdb1 & used
mkfs -c /dev/sdb1 10000
when asked for /usr in the [excellent] install script.
SO, the guts went on hda1 and the /usr stuff on /dev/sdb1 [AKA /usr].
While this may be OBVIOUS to the cognescenti, perhaps my experience
will be helpful to the less fortunate...
BTW, i KNEW that my first SCSi drive was employed elsewhere as
was the second half of sd1;  apparently the size reported is in
blocks of 512 bytes, wheres linux uses 1024 byte/block...
KUDOS to the SCSI freaks at woz etc.

Subject: Can't Compile Kernel 0.97
Date: 14 Aug 1992 16:12:57 GMT
Reply-To: [e-mail] (Sakari Aaltonen)


My attempt to build kernel 0.97 with gcc2.2.2 fails (at tools/build) because
the following files are missing::
     sys/types.h
     fcntl.h
     unistd.h

Specifically, they are not in /usr/include, that is, the directory that, as
far as I understand, should be used for tools/build.

I have files with these names among the kernel files. I tried copying them
into /usr/include, which makes the make succeed. However, build then fails
with the message
  Can't stat root device
Indeed, it seems that stat() ALWAYS returns -1...??


Does anyone know where I might obtain the missing files?

Out of curiosity: does anyone have an idea WHY the files are missing?
Or why stat() should return -1, no matter what the path,
"/usr/include", say?

Don't get me wrong: The faq and the meta-faq in itself are quite good

Sorry to disappoint you, but there are several people, who already
had this idea. No shiny new patents .. ;-)

Seriously: half of it is already there. The other half will be missing
until the variable block size code is completed. The first half is the
loop devices patch, that makes it possible to mount regular files on
file systems that support bmap as file systems.

Unfortunately, MS-DOS arranges its clusters in such an odd way, that
bmap can't be used on hard disks and on some floppies. But it works
with the old 360k (and I think also 1.2MB) format. If you have the
loop devices patch installed, you can try something like this:

# mount -t msdos /dev/fd0 /fd   # there's a 360kB floppy in /dev/fd0
# dd if=/dev/zero of=/fd/file bs=1k count=350
# mkfs /fd/file 350
# mount /fd/file /mnt

No problems here. Of course, I can't attest to any spped increase/decrease
with Linux, as I haven't bothered disabling the cache. For MS-DOG it is
definitely a help, tho.

It might not even be doing anything with Linux - would someone with more
info like to shed some light on this? Does the cache make enough of a
difference to be worth having? I *can* compile the kernel in about 2-3mins,
but that may just speak for the 486-33 and quick (relatively) IDE drives.

As an side, though, I have an opportunity to trade some hardware that I
have (a 20mb hardcard, SVGA card and 12-1mbx9 SIMMS) for 4-4mb SIMMS. What
kind of a difference will I notice going from 8mb to 16mb (4 of the 1x9's
that I have are in a box because I only have 8 memory slots - woops!)?

Yep. I've seen this too. My system is running off SCSI disks. I'd agree
with everthing listed above and add:

        - It can happen on WRITES as well.

Occasionally when I'm rebuilding the kernel, make will die with some
horrid error like it can no longer find the makefile it was working from.
Shorty thereafter, anything which accesses the disk seg. faults and dies.

When I bring the system back up, the filesystem is hosed. Usually the
superblock is scrambled so fsck just refuses to look at the drive.

Not good.
