How To Update The Kernel For Smoothwall Express 3.0

This is a guide for building a new kernel for Smoothwall Express 3.0. Smoothwall Express 3.0 is a UTM Internet Gataway Distro for X86 PC. But it is mainly used on older 386 PCs. If you want use it on a newer CPU, you will only get a "386"PC. So we must update the kernel for SW 3.0.

Here we suppose you have downloaded and installed SW3.0 DEV distro and have built your own SW3.0.

Move Patched Linux Source to /usr/src

mv /usr/src/expresscore/build/source/kernelruntime /usr/src/linux

Edit lilo.conf Adding New Kernel Options

Edit /etc/lilo.conf as below:

boot=/dev/harddisk
map=/boot/map
install=/boot/boot-bmp.b
prompt
timeout=70
lba32
default=Xeon
read-only
root=/dev/harddisk4
bitmap=/boot/image.bmp
bmp-colors=13,,12;14,,12
bmp-table=100p,348p,1,3,
bmp-timer=74,29,;,,
append="ramdisk_size=8192 no-scroll panic=30"
image=/boot/vmlinuz-2.6.16.55
	initrd=/boot/initrd-2.6.16.55.gz
	label=SmoothWall
image=/boot/vmlinuz
	initrd=/boot/initrd-2.6.16.55.xeon.gz
	label=Xeon

Make Menuconfig with P4/Xoen/SMP and Local version

Enter linux source directory.

cd /usr/src/linux

Config kernel.

make menuconfig

Set linux local version to Xeon.

Build New Kernel

make
make modules_install
make install

Build New initrd

mkdir /temp
mkdir -p /mnt/initrd
cd /temp
cp /boot/initrd-2.6.16.55.gz .
gunzip initrd-2.6.16.55.gz
mount -t ext2 -o loop initrd-2.6.16.55 /mnt/initrd
ls /mnt/initrd/drvier/scsi/*
cp /lib/kernel/2.6.16.55Xeon/drivers/scsi/*.ko /mnt/initrd/driver/scsi/.
umount /mnt/initrd
gzip -9 /temp/initrd-2.6.16.55
cp /tmp/initrd-2.6.16.55.gz /boot/initrd-2.6.16.55.xeon.gz
reboot
