booting uncompressed kernel on x86

booting uncompressed kernel on x86

[Pazzo Da Legare]

I would like to boot uncompressed linux kernel on a embedded x86,
should I apply a specific patch for this? I'm using grub boot loader
which should boot using elf image but I cannot find any clue.
Should I switch to another bootloader?

TIA

I did something some time ago - but it's only a quick hack to make my really 
slow (386DX/25) machine boot faster - see http://lkml.org/lkml/2005/7/1/206

Hi Ondreh,

Thank you for your answer.

I tried your patch but on my slow i486-like target (on 2.6.25 and
2.6.27-rc6) but it reboots immediatly after few seconds; during this
time I can see some random and colored chars on the screen.

It seems there is no way to do that without a specific patch

Dear ML,

Is there a standard way to boot on i386 arch using uncompressed linux
kernel (vmlinux)?
I'm trying to fast my boot process on a slow i486-like machine, I
found a patch for this subject (http://lkml.org/lkml/2005/7/1/206) but
it doesn't work.

TIA for you help
