Just to follow up, apparently the types in linux/types.h are only defined
if __KERNEL_STRICT_NAMES is not defined. <features.h> defines
__KERNEL_STRICT_NAMES by default. By passing -D_LOOSE_KERNEL_NAMES to
gcc, this behaviour is disabled, and my test code compiles without
problems.

You can simply copy the image to the floppy:
cp bzImage /dev/fd0
Notice that the loader build into the kernel
image is very primitive, there are better
loaders around like LILO and SYSLINUX. Also
notice that you cannot have a filesystem on
such a disk.
On RedHat systems The bootdisk used to start
the install program is a FAT formated disk
using SYSLINUX, the bootdisk created during
install is an EXT2 formated disk using LILO.
(Other distributions might do this different.)

If you are designing a new protocol it would be best to
specify one sequence that is the only way a linebreak is
ever sent. In that case I would prefer using a single
character instead of two, the character 10 is the standard
line break on Linux/Unix systems.
OTOH if you are implementing an existing protocol you
might have to talk to all kinds of existing lousy
implementations. If you want to be able to talk to
everybody, you must be able to handle all kinds of strange
input. Of cause none of your smart tricks to talk with a
lousy implementation may course your program to fail when
talking to someone who obeys the standard.

I've got a techno-phobic client who gets concerned when he sees all the
things going across his screen when linux boots up. This is enough of an
issue that I'm prepared to go in and build a customer kernel or whatever
is necessary to make a linux boot appear even simpler than windows. How
do I get control over what gets to the screen when linux is booting? Is
there some parameter I can pass while building the kernel to suppress its
screen output? Perhaps route it to /dev/null or something?
thanx & later,
Ben Scherrey

Did you re-run LILO after modifying /etc/lilo.conf? If not, LILO doesn't
know about the new settings. Running /sbin/lilo as root should update
LILO with the new configuration.

As I understand it, boot disks are specific to a particular kernel
configuration, so this would be expected behaviour...

You can just use unzip. I think it is installed
by default on RedHat systems, I don't know about
other distributions.

This is hard to answer as you haven't stated the config for the machines.
But provided the hardware is similar, the kernel configuration is appropriate
for each machine and the boot partition is the same then it will boot, The
messages on screen should indicate the problem area.

Sadly, the 'Internet standard line ending' is a carriage return
followed by a newline. So you probably should use it even if designing a
new protocol.

I've never tried, but there's an option quiet in later 2.2.x kernels
which lowers the console log level.

Why is that sad? It's the correct way to do this.
