question about compiling the kernel

question about compiling the kernel

[Jie Zhou]

Hi, all,

 I got about 30 warning msgs like this during the process of "make
bzImage",   is it a fatal problem or not?
  "Warning: using '%eax' instead of '%ax' due to "l" suffix"

 2. after 'make bzImage', if I don't have any module to install, then I
don't need  to run either 'make modules' or 'make modules_install',
is this correct?

3. After I run the /sbin/lilo, it says the new kernel is added to the
system. HOwever when I restart the system and go into the labeled kernel
I choose, the system gets stucked after these two lines:
Loading kernel.......................
Uncompressing Linux...OK, booting the kernel.

Can you give me some advice on this. Thanks a lot for your kind reply..

Jie

Nothing to worry about.

Correct.

Make certain you compiled the kernel for the proper CPU type (ie. don't
try to run a Pentium II kernel on a 486)

Not true.  If you compile the kernel for a Pentium Pro or higher cpu,
GCC will include some instructions (cmovxx in particular) that do not
exist on earlier processors.  Since the fault handlers are not set up
yet when booting the kernel, this results in a silent crash.
