I'm running Linux in the DOS loop configuration on my PC. I'd like to
increase the size of the DOS loop that I initially allocated for Linux. Can
anyone tell me what the process is to do that? I couldn't find it in the
docs or FAQs.
Is it necessary to reinstall or can the config file that mounts it be
edited?
Thanks!

hi tom,
Has this ever worked for you on any version of linux?
I have a hacked version of Suse 6.4 on my home PC and use a "no-name"
modem for downloads. I'm using Netscape Communicator (free version)
that I downloaded from somewhere. I have being using my modem with
2.2.16, 2.2.17, and now 2.4.0test10 kernels without problem.
I never have any problems with large downloads - the download box
occassionally shows a (say) "20% of 200k/s (stalled... ) " message
sometimes but usually continues after a second or two.
I'm no expert in modems but you could try one of the following (if
nobody
else has the answer):
- download latest version of wvdial from sourceforge ==> unlikely to
make a difference.
- Read the wvdial and pppd man pages and documentation to see if
there is some
way to run pppd with logging turned on to a log_file or something...
- Download a later kernel from source into /usr/src/ and compile it
see the kernel howto.
- download a protocol analyiser such as "ethereal" from source
and install. Then capture all network traffic on
your pc while doing a large download and when it stalls
stop the
analyser and post the results here or in comp.os.linux.networking.
==> Last resort and will at least show what kind of network traffic is
occurring
when load fails.
- Borrow a different brand external modem from a friend and install
on your Suse PC. Maybe your current modem has some non-standard
configuration.
- Have you tried alt.os.linux.suse (but I think this problem is
not distribution related, linux is linux!)
These are the only suggestions I can think of.
regards ,
Noel,
Dublin,Ireland.

Sure. Man bash (if bash is your shell). It tells you very clearly:
A login shell is one whose first character of argument
zero is a -, or one started with the -login flag.
An interactive shell is one whose standard input and out-
put are both connected to terminals (as determined by
isatty(3)), or one started with the -i option. PS1 is set
and $- includes i if bash is interactive, allowing a shell
script or a startup file to test this state.
Login shells:
On login (subject to the -noprofile option):
if /etc/profile exists, source it.
if ~/.bash_profile exists, source it,
else if ~/.bash_login exists, source it,
else if ~/.profile exists, source it.
On exit:
if ~/.bash_logout exists, source it.
Non-login interactive shells:
On startup (subject to the -norc and -rcfile options):
if ~/.bashrc exists, source it.
Non-interactive shells:
On startup:
if the environment variable ENV is non-null, expand
it and source the file it names, as if the command
if [ "$ENV" ]; then . $ENV; fi
had been executed, but do not use PATH to search
for the pathname. When not started in Posix mode, bash
looks for BASH_ENV before ENV.
If Bash is invoked as sh, it tries to mimic the behavior
of sh as closely as possible. For a login shell, it
.....
and the same sort of thing with tcsh. Now WHAT is your problem? You
can see that if you used a login shell, you executed
/etc/profile
~/.profile
unless you had a .bash_login, which beats out the .profile, unless you
had a .bash_profile, which beats out a .bash_login.
For tcsh and such, the canonical order is
/etc/cshrc
/etc/login
~/.cshrc
~/.login
for login shells, according to my memory, and subject to future
correction by kibitzers here.

What boot loader do you use?
Whatever, look at its man page. "man lilo.conf" by default. "man grub"
sometimes.

You no unnerstan.
Find out what a serial port is. Read the modem HOWTO.
To the kernel, it's an IRQ and an io address that speaks serialport-ese.
So set one of the existing devices to use that IRQ and io address using
setserial. You KNOW it makes sense.
If you truly want to make another special file in /dev/ just for this
porpoise, at least name it /dev/silly. And surely you've got zillions
of ttyS? pointers already there? Make some more if that wasn't enough!
That's mknod /dev/ttySilly c 4 68, if you want.

Ooooh, by putting some more ram in your boots, I think. Remove your

No, they'll magically survive the destruction of the place they live, and

An inflatable pillow. Also a boot loader.

Somehow I think you can help yourself. The manual for your distro is a
good place to start.

Subject: Reiserfs + lilo + booting issue
Date: Thu, 21 Dec 2000 22:59:27 +1100
Hello,
I am using Linux 2.2.18 (with reiserfs 3.2.59 compiled on the kernel). I
have successfully converted root file system from ext2 to reiserfs and
found the system is booting OK. (using rescue floppy disk)
But after converting /boot filesystem from ext2 to reiserfs and while
trying to run lilo, I get the following error message: "Hole found in map
file (alloc_page)".
But the system is booting and working fine from the rescue floppy disk I
have created before the conversion.
My configuration files are as follows:
1. /etc/lilo.conf:
boot=/dev/hda
map=/boot/map
install=/boot/boot.b
prompt
timeout=50
linear
default=linux
append="mem=128m"
image=/boot/vmlinuz-2.2.18
label=linux
read-only
root=/dev/hda12
image=/boot/vmlinuz-2.2.18.old
label=2.2.18.old
read-only
root=/dev/hda12
image=/boot/vmlinuz-2.2.14-12
label=origional
read-only
root=/dev/hda12
2. LILO version 21
Can someone help me on making my system to boot from the hard disk instead
of rescue disk?
Thanks in advance,
Hari.

Subject: USB not loading in Redhat 7
Date: Thu, 21 Dec 2000 12:10:05 GMT
I am a relative Linux newbee and am struggling to get USB up and
running to access an Epson 740 Inkjet printer on a Redhat 7.0
installation on a Dell 400-MHz P-II PC.
It appears that USB support is not loading even though it tries to.
Does Linux support IRQ sharing? That may be my problem.
It appears that I have a system that is probably not optimal for Linux
as I have a DVD system that I never use and a sound system that is not
supported by Linux, both of which consume lots of IRQ and other
resources. I did much better on my new Dell at the office. I had not
even considered Linux when I bought this PC over two years ago.
Here is a portion of my BOOT.LOG file...
Dec 17 16:46:08 dell733@home modprobe: /lib/modules/2.2.16-
22/usb/usb-uhci.o:

shows my SCSI controller on IRQ 9 but does not "see" the USB

================= If using lilo ===========================
edit /etc/lilo.conf and add
append="mem=128M"
then /sbin/lilo to install the change.
Next boot gets the change
