Workstation 4.0.5 environnement on a Compaq Evo N610C laptop (running 
Windows XP Professional), the following error appears after "Reading

Installation in graphic mode hangs without error.

Same problem with different installation option (custom system, 
server, gnome workstation).

Same problem with multiple installation CD-ROM.

Problem is permanent and reproductible.
