This may be a stupid question, but I just have to know.  If my 
DOS partition gets a virus, is my linux partition in jeopardy?

Subject: Can Linux mount NeXT filesystem
Date: 21 Jun 1994 17:34:23 GMT

I will be setting up a NeXTstep OS on a harddrive and I have Linux on another hard drive.

I would like to be able to mount the NeXTstep filesystem from Linux. Realize I am not talking about the NeXTstep running at the same time as Linux, I just want
to mount the NeXTstep filesystem from Linux to use the ftape backup to my CMS
250 tape drive (which is not supported by NeXTstep) and to transfer files if
desired.

From a friend who has NeXTstep, he says the filesystem is a standard BSD 4.2 
filesystem whatever that means.  I'm curious if other of the available filesystems which Linux has as options would work.

I'll be grateful for anyone who knows or can give some suggestions on how
to find out.

(BTW I am not interested in discussing the relative merits of Linux vs. NeXTstep because I think Linux is great but am also interested in working with NeXTstep)

Thanks for a response.
If possible please answer in the newsgroup because other people might be 
interested. (I get tired of seeing the request to answer my e-mail because
people don't read the groups often, or some other obscure reason. There are
many people on the net who quietly read alot of mail and who may or may not 
be interested in the response. )

Hmmm... what exactly are the symptoms you're seeing?  When I tried an

After turning on debug printf's and poking around for a while, I found that

Adding a 1ms delay fixed that problem.

Try applying the following patch and see if things get better:

Use another tar command with the 'M' option:
   tar cMf /dev/fd0 tar-file.gz
tar will prompt for a new floppy when the current one is full.
It would be nice to be able to combine the 'z' and 'M' options
of tar as in:
   tar cMzf /dev/fd0 ....
but GNU tar 1.11.1 does not support the combination of 'z' and 'M'.

The GNU tar in Linux has an option -L to let you specify the tape length
(floppy size in your case).  It'll prompt you to change tape/floppy
when every other specified length has been written.

Well, I have something more comparable:  can Sun 386i run

My ghostscript x11 display is completely unreadable. Is that because of fonts
problems or because I run virtual 1024x768 on 640x480 display ? Certain pixels
appear to be missing, thus each letter is a disjoint set. 

The eps9high output on an epson 9-pin fx printer is not much better. It is
kind of smeared and not complete near the edge of the paper.

Please no answers like : get HPLJ iV and NEC 5FG.

Why would you stop at 1024x768?
What if you want 1152x900, you can do it on the new S3s that support an
accelarated 1152 width, but you get close to zero cache and performance is
lousy. Also what about using a 1024x768 display and a 1280x1024 virtual 
display? to some of us this would be very nice (e.g. I like 1280x1024 to
run magic). Just because your monitor can't do the higher res, doesn't mean
you can't use them.

On an ISA card it can make one hell of a lot of difference if you are using
large fonts or lots of bitmaps. The extra ram is used. Also the extra meg
of ram doubles the ram bandwidth, which atleast on the newer S3 cards can
be put to good use :-) The extra meg will speed up stipples and font
noticably (not pixmaps much as the cache is lousy in 2.x and not in 3.0).

When a 16bit S3 server is available then you sure would be glad you have 2MB,
one of the reasons I haven't done anthing on adding 16bit support to the S3
server is that I only have 1MB on my 801, and I can't find anyone that sells
<=60ns DRAM to expand it...

I have heard before that Linux does not zero the undocumented fields
in a directory entry when it creates a new file.  I don't know if that
has ever been fixed.
Anyway, it seems like Laplink is using these undocumented fields somehow,
which is suspicious as well...  DOS itself does not use them.

Well, there is a  rec program with the vplay package (I think it's called
vplay). But it doesn't record 16bits, it just records horrible noise.
I don't know why, since I have the IRQ set to 12, and the DMA set to 7
(PAS 16) and it should therefor be able to record 16bit.
vplay is on sunsite.unc.edu in /pub/Linux/apps/sound I think.

Subject: Problems with SCSI disc
Date: 24 Jun 1994 05:49:48 GMT


I recently bought a new SCSI disc, but I'm having trouble getting it
to boot. 

Anyone willing to help ??


The scenario is ...

        Drive : Seagate ST-4767N
                1356 cyl, 15 heads, 65 sectors, 676MB formatted
                
        Controller: Future Domain TMC-950 clone
                BIOS Rev V7.0


I've split it into 4 partitions, and want to make /dev/sda1 the root
filesystem and bootable.


Given that the drive has 1356 cylinders and 65 sectors/track, I ran
the dparam.com utility to see what the BIOS though it was. It printed

        34  38  1006

which I took to mean 34 heads, 38 sectors, and 1006 cyls going by what
it said in the SCSI-HOWTO.

Here begins the saga  ;-)

- fdisk doesn't like the drive so I always have to tell it what the
  various sizes are. i partitioned the drive telling fdisk the numbers
  given by dparam

- LILO cannot deal with the drive without a disktab, so I set the
  disktab to the numbers given by dparam

- I remade the boot sector and tried both MBR of /dev/sda and also the
  boot sector for /dev/sda1


If I don't use the LINEAR option to LILO, I get just the 'LI' when it
tries to boot.

If I do use the LINEAR option, I get an endless stream of 'LI's down
the screen until I reboot.


I've tried many combinations of size settings, disktab entries, etc
but so far none have worked. 

The FAQ seems to indicate that this is geometry problem - any idea how
I might get this going ?

Any thoughts appreciated,
Thanks in advance,

davida
