dos2unix $i;

...this assumes you have "dos2unix", and it assumes you have no binaries
in that directory. You may want to change `ls -R` to `ls -R *.c *.h` or
something. dos2unix is a relatively standard part of Unix; if it's not
there, you can do the same thing using tr like so, replacing the dos2unix
line with this:
cat $i | tr -d '\r' > temp.txt ;
mv -f temp.txt $i ;

Use fdisk or cfdisk, and add another "Linux Swap" type partition. Then
"mkswap /dev/HDXY" Simple, eh? You might need to add a line to /etc/fstab
like so:
/dev/hdXY none swap defaults 0 0
X being the drive letter, Y being the partition number you made using
fdisk, of course. Immediately after following these steps, you can
"swapon /dev/hdXY" to activate the swapspace. Everything will work
transparently upon the next reboot.
If you didn't have any non-partitioned disk space and still needed to do
this, you'd do it like so:
# dd if=/dev/zero of=/swapfile bs=1024 count=16384 (16384=16M; modify
for your needs)
# sync
# mkswap /swapfile
# swapon /swapfile
And the /etc/fstab line would have /swapfile in place of /dev/hdXY. HTH,
HAND, bonne chance.

The right three-quarters of my screen have a slight but noticable
horizontal grain which gets more prominent further toward the right.
This problem is not present when running MS Windows. Are there settings
I could fool with in XF86Config or something to make this go away?
Right now I'm running at 1024x768 16bpp on a Guillemot Xentor 32 (NVidia
TNT2 chipset). Does anyone have any ideas?

Hi Bob,
Did you mount the floppy disk after formatting it? Before you can access
a disk, you have to mount its filesystem...floppies are (usually) not
mounted automatically. Try this command:
mount -t <filesystem> /dev/fd0 /mnt/floppy
where <filesystem> is the file system listed in /etc/fstab for your floppy.
The major filesystems (that I know about) are ext2 (second extended),
msdos, and vfat (windows).
Your floppy entry in /etc/fstab should look something like this (with your
appropriate filesystem in the third field):
/dev/fd0 /mnt/floppy ext2 noauto,owner 0 0
(Check and make sure this is set up before you issue the mount command)
When you get through using the disk, you should then unmount it. The
command is :
umount /dev/fd0
Of course, you can check the man pages for more info on these commands.
Good luck,
psw

Subject: query on tar backup
Date: Fri, 07 Apr 2000 03:04:43 GMT
we use tar back up for copying on to tapes as well cd's. when we take
backup the entire path name of the file is written to archive. when we
extract the file the path is again created under the current working
directory(cwd). we wish to create only extracted file in the cwd and
not with complete path.
we acheive it by extracting the file to STDOUT and then creating it in
the cwd. when extarcted file is compressed it is more complicated. can
this be minimised by an optional switch?
trust i have explained our requirement.

You can create an additional swap file in an existing partition
without repartitioning. Do man mkswap.

Usually when I'm building a kernel i got for 'make mrproper;make
config;make bzImage; make modules; make modules_install'
then copy the image and system map to /boot and reconfigure LILO.

I used phatlinux for a few months and the very first thing I had to do
was understand that in the linux.bat, you have to put the correct amount
of ram. It is set for 128 meg, but I only have 64 meg. I edited this
with notepad to 64 meg and saved it. The next time, it booted up fine. I
find Peanut-Linux 7.6 to be a better dos-loop version that phatlinux,
but phat does have linuxconf. If that is not the problem, then please be
more specific on what you did according to the install text that came
with it. I forgot the password was "phat" and couldn't login first time!

Hi Doug,
Pl. find my answers below:

Answering your second Q first, to determine which Virtual Memory Area (VMA)
the address you retrieved it is only necessary to traverse the
vm_area_structs , it is not necessary to go through the page
table/ddirectories etc.

Any linear address , in your case that given by EIP , will be split into
three parts(I do not remember offhand how many bits each of the three has
out of the 32 bits).The first part will be the offset into the page
directory, (the base of which is pointed to by CR3 register).At this offset
in the page dir, the base address(physical) of the pmd can be found.The
second part of EIP will now be an offset into the pmd. At this offset, the
base (phy) address of the actual physical page in memory can be found. The
third section of the EIP is an offset into the page

I haven't checked all the titles you listed, but I did check this one. It
appears that most or all of the chapters are mostly encrypted. An
occasional sentence comes through. Also, for some bizarre reason, some of
the chapters of this book have gotten mixed up with chapters from my own
_Linux: Networking for Your Office_ in the online garbled previews. As far
as I can tell, this site puts up mostly-garbled chapters as a sort of
preview to get people to buy the books. If there's a way to get the full
text for free, then as an author I'd have a problem with that.

Check your script with something like "cat -v" or "sed -n l" to
see if you have any non-printing characters or escape sequences
