[CentOS] CentOS 5 netinstall problem

Hi, all.

I'm attempting to install CentOS 5 via netinstall from <mirror.centos.org/centos/5/os/i386> & it gets as far as formatting the disk but when it gets to:

'Starting install process. This may take take several minutes...'

it hangs forever (well, a couple of hours).

Dropping down in a console I see it's telling me:

'Preparing to install'

then nothing. 'top' shows activity for Anaconda but very little.

This is on an old Poweredge 650 with 3GB's of RAM on a secondary drive. The primary drive has CentOS 6.4 running on it quite happily so the hardware's up to it.

I chose to install the 'Server GUI' packages because I was curious. Maybe herein lies my problem?

Any help appreciated.

Cheers,

Phil...
