I came across several errors whilst trying to install VMware server 1.0.2 on Ubuntu 6. Below is the error messages and their corresponding solutions:

You'll probably get asked for xinetd, make and GCC so get those first

sudo apt-get install xinetd
sudo apt-get install build-essential

sudo apt-get install linux-headers-`uname -r`

Trying to get Unbuntu 6.1 server AMD64 installed and it sticks on the part:

.
Decompressing the kernel
Booting the kernel

Seems to be quite a few others having the same issue, I am having this on a Dell Poweredge SC1435.

Anyway quite a simple fix, there are various different syntaxes for turning off APCI but I will detail what worked for me anyway.

Upon booting off the CD press F6 on the install from CD option, there you can enter boot parameters.

Currently mine ended with ..quiet --
