I recently installed 1.9 on a 2Ghz Celeron machine with 768Mb of ram, without incident. It is still running fine but I gave it to my son.
My primary machine has been a 3Ghz P4 with 2Gb ram, a Realtek Integrated Sound Adapter, Nvidia Gforce 6200OC video card, three 200Gb SATA hard drives and a Plextor 716A DVD Writer. I was running XP MCE and I want to dual boot with Ultimate 1.9, as I did with the other machine.
When ever I boot with the LiveCD and choose Run/Install, I get the bar moving back and forth, for several minutes, and then it freezes. The checksum for the DVD matched the one on the web site. I downloaded and burned the ISO file several times, at 4x, with both my Plextor 716A DVD Writer and an LG DVD Writer using both Nero8 Burning Rom and InfraRecorder. Same result.
After a few minutes of the Freeze, I get a Black screen with White text
Preparing Restricted Drivers
Setting System Clock
Starting Basic Networking
Starting Kernel Event Manager
Loading Hardware Drivers
then I receive6 or 7 lines of text with a path ending with "Abnormal Exit"
Any idea how to debug this problem and get 1.9 installed?
