Installed CentOS 4.3 and chose a custom setup, removed all partitions and let it auto-partition using LVM and then choose the minimal packages option.

# yum install gcc

# yum install kernel-devel

# cd /usr/local/src

# wget *first post and it complained about urls*/linux-2.6.16.tar.gz

# wget *first post and it complained about urls*/web100-2.5.10-200604071159.tar.gz

# tar -zxvf web100-2.5.10-200604071159.tar.gz

# tar -C /usr/src -zxvf linux-2.6.16.tar.gz

# rm -rf /usr/src/linux

# ln -s /usr/src/linux-2.6.16 /usr/src/linux

# cd /usr/src/linux

# patch -p1 < /usr/local/src/web100/web100-2.6.16-2.5.10-200604071159.patch 

# cp /usr/src/kernels/2.6.9-34.0.1.EL-i686/.config ./config.save

# make mrproper

# cp config.save .config

# make menuconfig

Here's where the fun begins...
