Huh? Who replaced this with variable bit density zones? Not on the Mac or

CD-ROM drives... they are both variable speed.

Maybe I didn't word that right... What I intended to say was the variable
|
|
speed capability of 800k capable Mac drives would be hard to fake in
|
|
software. But writing GCR on an MFM drive _should_ be possible if the
|
|
controller circuitry is sufficiently flexible. Just doing GCR may not be
|
|
good enough to read 800k disks on a PC 1.4M drive, and I doubt that using
|
|
variable bit density zones would be good enough either. Of course I could
|
|
be wrong. At any rate, I think it is highly unlikely that anyone will
|
|
ever write a driver or program for Linux to read 800k Mac floppies... since
|
|
they are being phased out there isn't much incentive to do so anyway...

You should certainly learn how to compile your own kernel...

Subject: Error with ld when trying to use CheckerV0.3 (ld.so.1.9l.4) on linux
|
|
Date: Thu, 10 Mar 1994 05:38:46 GMT
|
|
|
|
I am trying to get the Checker program (V0.3) to work and
|
|
am having trouble with ld when I try to run Checker.
|
|
|
|
Specifically , I am running linux-0.99.15, and I just installed
|
|
gcc2.5.8, libc.4.5.21, and CheckerV0.3 (I installed all of the
|
|
above as I wanted to use Checker !! and the README said I needed
|
|
a gcc at least 2.5 something (I was at gcc2.4.5 before) ).
|
|
|
|
In installing the above I installed ld.so.1.9l.4.
|
|
|
|
After all this when I try to compile a program with checkergcc I get:
|
|
# checkergcc test.c -o test
|
|
ld: unrecognized option `-checker'
|
|
Usage: ld [-d] [-dc] [-dp] [-e symbol] [-l lib] [-n] [-noinhibit-exec]
|
|
[-nostdlib] [-o file] [-r] [-s] [-t] [-u symbol] [-x] [-y symbol]
|
|
[-z] [-A file] [-Bstatic] [-D size] [-L libdir] [-M] [-N]
|
|
[-static] [-nojump] [-dll-verbose] [-S] [-T[{text,data}] addr]
|
|
[-V prefix] [-X] [file...]
|
|
|
|
I tried to use the ld.diff file (that came with the CheckerV0.3)
|
|
to make a new ld.so
|
|
, but it seemed wildly different
|
|
than the ld.c file the diff file was compared against (the ld.diff
|
|
file starts it's changes at line 1154, and the ld.so.c file
|
|
for ld.so.1.9l.4 has only 458 lines.
|
|
|
|
Can you help/ any suggestions ?
|
|
|

Thanks,

I thinks there's a new bug here. I also noticed LOTS of serial overruns on
|
|
one occasion from my *mouse*. This is for the first time ever, with ALPHA-1.0.
|
|
The condition persisted until I rebooted. Haven't seen it since.
|
|
|
|
Of course, I am now also running with my hd.c enhancements for Multiple-mode
|
|
and IRQ-enabling, so interrupt latency is no longer a big problem.

Subject: Linux pre-1 bug with NFS
|
|
Date: 9 Mar 94 21:37:09 GMT
|
|
|
|
I had a NFS server crash on me today while I was running a "df"
|
|
command, so I switched to another V.C. and issued the command
|
|
kill -9 pid, where pid was the pid of the df command.
|
|
Normally this works, since I mount the server with the options
|
|
(intr,soft) but this time, the process just sat there with
|
|
a "D" in the ps status field forever, no matter how many times
|
|
I sent it a kill signal. This used to work in previous versions,
|
|
so it leads me to believe that it might be a bug. Thanks!

I have an AMD 486DX-40, running at 50MHz (overclocked). I just
|
|
compiled the AMD floating point bug "demo" using PCC (Personal C
|
|
compiler, which is shareware). It uses real mode, with 64k segments
|
|
and all that, but that shouldn't affect the floating point processor.
|
|
|
|
I passed the test. No bugs here, at least not in the circumstances
|
|
present when I ran it. I am willing to run it again if anyone can
|
|
suggest circumstances likely to tickle a bug. I cannot run Linux - at
|
|
least not until I get the new hard drive!
|
|
|
|
Sorry, I don't know a serial # for the chip - I would have to remove
|
|
the motherboard in order to get the chip fan off.

I was wrong here. It depends on reason for disconnect.
|
|
After loss of carrier it works fine. If disconnect
|
|
on close, then problems are present.
|
|
BUT it even did not assert DTR when there are active

processes like compile, ....

RTS/CTS flow control, modem Hayes ULTRA 96.

After successful uucp session next two

attempts gives I/O error. On third attempt
|
|
connection goes fine again. If I run cu
|
|
the same problem after session if I disconnect
|
|
by ~. If disconnect initiated by remote side
|
|
everything is fine.
|
|
|
|
So the problem somehow related with tty output queue.
|
|
May be the modem drops CTS very fast
|

after DTR going off?
|

I am also puzzled by long delay (about 1 second) between

open of line and DTR assertion.

Actually, mine (running on a 386 with pl15d) runs to completion.
|
|
After a minute or two, it reports:
|
|
|
|
Memory mallocatable ~= 1045497 Kbytes
|
|
|
|
This on a machine with 8M RAM, 10M Swap. 1 GB allocated?
|
|
Pretty good! A more useful(?) version of that program would
|
|
try _using_ the memory it has allocated, as any _real_
|
|
program would. Then the pages would actually get mapped,
|
|
and you would get a realistic answer. It is scary seeing
|
|
your swapspace fill up steadily, though!

The Adaptec 152x driver, which has been in the kernel for some time,
|
|
will work with that chip. Use a recent kernel, because the earlier

version of the driver didn't work quite right on some fast connections

to the 6260, like LB and MB-direct ones.

Well, it has certainly been around for a while (it was there in the pl10
|
|
MCC kit that I ran last year ...) but I think most people use 'host'.
|
|
This one bothered me, too, so I finally got around to looking at it a
|
|
few days ago. I fetched the newest version of the bind kit for Linux
|
|
that I could find. I'm not sure at the moment whether this came from
|
|
sunacm.swan.ac.uk or from sunsite.unc.edu. [ Aside - does anyone know
|
|
of an ftp client that logs your fetches ??? ]
|
|
|
|
I never got past compiling nslookup - it worked perfectly, out of the box.
|
|
|
|
Since I'm not sure where I got it, I've put a .tgz file of the nslookup
|
|
source (and binaries) in pub on nepahwin.cs.laurentian.ca - if you want
|
|
to fetch it from there.

Subject: Short delays outside of the kernel
|
|
Date: Sat, 12 Mar 1994 16:29:33 GMT
|
|
|
|
I'm in the process of building a EPROM/Microcontroller board. I'm planning
|
|
on writing the software under linux. One of the requirements is to have
|
|
a very short (100 uS) pulse to program the parts.
|
|
|
|
I've examined the kernel because I remembered that BogoMips had something
|
|
to with short delays. This led me to linux/delay.h and the __delay and
|
|
udelay calls. Seems straightforward enough.
|
|
|
|
I have two questions:
|
|
|
|
1) Can I use these calls outside the kernel? Since they are inlines I don't
|
|
think that's a big problem except getting access to loops_per_second.
|
|
|
|
2) Bigger problem. is the udelay call interruptable? I examined their
|
|
use in a couple of the drivers and it wasn't clear to me if interrupts
|
|
were turned off or not. If the udelay call ever got interrupted then
|
|
my poor EPROMS and Microcontrollers would start releasing magic smoke ;-)
|
|
|
|
I'm curious about the implications of holding the processor for 100 uS
|
|
at a time. Does anyone know what kind of effect these delays would have
|
|
on the system.
|
|
|
|
Lastly I'm willing to use one of the PC hardware timers if it's available and
|
|
can gurantee a 100 +- 5 uS blip on my output line.
|
|
|
|
Do I need to write a mini device driver to do this or can I run it from
|
|
user space?
|
|
|
|
Thanks for any info you can offer.

P.S. The interface board is realy simple. I bought a dual serial card with
|
|
an empty socket and interfaced to it some TTL on a perfboard via a DIP
|
|
jumper cable. The card gives you 8 decoded I/O ports, a clock, and an
|
|
interrupt plus an extra serial port. Cost less than a empty proto card
|
|
from Rat Shack.

Subject: Kernel with cluster08a doesn't boot from floppy with filesystem
|
|
Date: 9 Mar 94 22:19:42 GMT
|
|
|
|
The (terrible long) title says it all:
|
|
|
|
I built a kernel with cluster patches 08a included, put this kernel
|
|
on a floppy with a minix filesystem and installed lilo on that floppy.
|
|
Unfortunately the floppy refuses to boot. More precisely: the kernel
|
|
stops when it should copy the boot floppy into the ram disk. The screen
|
|
reads something like:
|
|
|
|
RAMDISK: Loading 1200 blocks into RAM diskRAMDISK: I/O error on block 0
|
|
|
|
It works if leave the cluster patches out. By the way: My kernel is
|
|
version 0.99pl15b.
|
|
|
|
Any ideas? Looks like a bug?
