Is there no tool that can trim down e.g. glibc for a given set of user
programs, eliminating all parts that never are called ?

I seem to recall that there is (was?) such a tool, but I've
certainly never seen it at work. Would be nice if someone who
knows more could share his info with us.

Anyone ?

Did you try to format the USB as a bootable DOS device. Doing this should
sow whether you face a Linux problem or a BIOS problem.

Actually, calls to the BIOS will read the CF. That's how scsi drives are
booted. The boot loader calls the bios to read the rest of the kernel in.
As far as the boot loader is concerned, it'll read just like an IDE drive.

If the BIOS supports CF, then all you need is CF support in your kernel.

The kernel will have to have the CF driver in the kernel, not as a
module.

This might not be correct as the BIOS is unable to get into the
loader
stage itself.
It doesnt matter if the kernel is compiled with the required driver
as a
module or not! It has not
reached to that stage.

Right. Lilo or whatever has to have CF support as well.

my kernel is monolithic so I didn't choose anything as a Module in the

DOS accesses all drives through the BIOS, so it does not know whether
it's USB or not.

Do you remember remote booting DOS e.g. from a Novell-Server or using
BootP on a Linux/Unix Server ?

Here you use an Ethernet card that has a PROM that installs as a BIOS
extension (you know: before booting from a disk, the BIOS calls all
functions it finds that identify by a special signature at one of
several addresses in the 16 Bit address range.)

The Ethernet card BIOS extension (with the help of the server) converts
a file on the server into a drive on the remote machine. Unmodified DOS
boots from this fake drive just fine. In the autoexec.bat on that remote
drive you install the network access software (client) for DOS and now
you can access any data on the server.

Linux can't work that way, as a BIOS drive can only be accessed in 16
bit mode that Linux does not support. So Linux needs to install it's own
hardware access to the (USB) drive, while DOS does not need anything
like that.

Thus the Linux boot process is much more complicated. Here at first a 16
Bit program needs to load the next stage into RAM via the BIOS interface
and this stage needs to install 32 bit drivers for Linux use.

If you say you can't even boot DOS from the USB device something is
wrong in a very early stage, that has not much to do with booting _Linux_

Support isn't enough; your boot media can't be a loadable module, it has
to be compiled into the kernel.

If your bios supports booting of CF then it'll provide what looks like an
IDE device for long enough to load the kernel. Lilo need never know that
it's bios calls are getting data from the CF.

No pure Linux can guarantee this. Now and again you might see thread
start delays of several 100 msec. Device drivers work much better but
there still is no guarantee at all. This is "soft realtime": works fine
for multi media and similar stuff but it's not reliable if something
desasterous happens if a deadline is not met.

If you need better accuracy you need to add something like RTAI.
