For example the fan on the CPU ceases to spin, and the CPU gets hot and stops
working. This is very common, much more frequent in my experience than hard
disk crash.

It is not clear what you are asking. CVS gives you certain controls.
What specific control does your boss need which CVS does not provide?

On my RH6.2 machine I have the file /etc/conf.modules which contains only a
couple of statements like 'alias eth0 eepro100' and 'alias parport_lowlevel
parport.pc'. I am expecting to find a list of the modules that I defined in
the .config file before compiling, linking, module installing etc. Perhaps
someone can guide me a bit in three areas: 1) How does one go about adding a
module explicitly (please be a bit verbose). 2) Can I expect to see with cat
/proc/ksysms that modules exports at boot time, or only when the module is
loaded. 3) What determines when the module is loaded (I presume an access to
a resource that it registers, but where is that registration done file-wise
speaking).

I'd like to add to this question by asking, how does the kernel go about
adding a new module (file-wise speaking) when 'make xconfig' is used to
check a new module for compilation. What files are modified that then allows
that module to be automatically loaded and its symbols exported at startup
time?

If you need exactly a VSS look-alkie, that might be illegal. But if you
just need a visual interface, one candidate (KDE based) is cervisia.
It isn't clear from your note if one requirement is to prevent updates
of the repository (let most people just download, and only a few
authorized to make changes). That can be done with CVS, e.g., with a
"writers" file.
If you want to control CVS branching more fully, there was an article
in Dr. Dobbs recently which provided a good idiom. I've implemented
that in a python script:

Subject: USB vend/prod determination
Date: Sat, 24 Mar 2001 20:08:30 -0800
I am studying how a USB driver gets connected to a particular vend/prod ID.
I can see where my device is enumerating and the USB stack reads the
vendor/product ID off of the chip in usb.c:usb_find_drivers. My question is,
where is the connection between a vendor/product ID and a module. Is there a
file somewhere with the connection between vendor/product ID's and
associated drivers? Is each one hard-coded in the module itself? How does
the linked list (if there is one) of vendor/product ID's and USB drivers
work. Any suggestions/pointers, will as always, be gratefully appreciated.

Check out Perforce. It allows for versioned check-in, check-out, and

Subject: wipeinfo, secure delete, device driver
Date: Sun, 25 Mar 2001 07:15:26 -0500
When working for a government agency in computer maintenance,
special procedures are required for deleting sensative data from
the hard drive. In a classified environment, the hard drive must
be written with all ones, then all zeros, then all ones. It is
suggested to repeat the procedure three times. This "secure delete"
procedure was implemented in DOS by Norton utilities "wipeinfo"
command. Is there a Linux version of this command?
I have used the /dev/zero device to write 0's to the disc, and
thought there should be a /dev/ones device to write all one's.
Could I simply modify the /dev/zero code to make it write ones instead?
Where do I find the source code for this device driver?
Has this been done before?

The aic7xxx driver shipped with Slackware 7.1 (object file dated 6-20-2000
- 153,576 bytes) is broken, at least for the Adaptec 2842VL.
It dies with a BRKADRINT error after showing the first attached device.
The driver shipped with Slackware 7.0 (dated 10-21-1999 - 126,964 bytes)
works fine.
Anyone know where updates to this driver are available?

To get a module autoloaded, it has to be indexed by "depmod -a", and
have an alias for the resource it provides in /etc/conf.modules (or
/etc/modules.conf depending on personal preferences :) )
You can insert and remove modules by hand with insmod <modulename> and
rmmod <modulename> respectively. You can see a list of installed
modules by either using lsmod, or viewing the file /proc/modules .
Hopefully that answers a few of your questions...

.global declares a symbol that will be exported from this file
and available for the linker or other files. .extrn is the
opposite, it declares a symbol that is defined elsewhere.
> There are many instructions that begin with a dot (".").
> .word is same as word in i386 instruction??
. is the flag for AT&T assembler pseudoinstructions.
Otherwise, the instructions have different mneumonics
and syntax than Intel ASM: For example:
mov eax, [array+ebp+ecx*4] Intel syntax is
movl array(%ebp,%ecx,4), %eax AT&T syntax.
> Can somebody give me some informantion???
Sure. Have a look at http://www.linuxassembly.org
> In AT&t asm ,there is no data segment or code segment
> declaration ?? Which take their places???
There are segments, usually: .text for code, .data for
initialized data, and .bss for uninitialized data. A
typical program hello.s looks like this [untested]:
.text
.global _main
.extrn printf
_main:
pushl $fmt
call printf
addl $4, %esp
ret
.data
fmt: .asciz "Hello, World!"
