Comment 46 for bug 105195

+1 - the options I needed are "-cpu coreduo,-nx" rather than 'nx' as mentioned by Johannes

I have an older Core Duo (Thinkpad X60s) which does support the nx flag, but I must forcibly disable it if I want XP to run ... same store - stage one ('DOS-style' install works, but the first reboot to complete the installation just hangs at 50%CPU usage on a black screen..)

gdh@gdh-x60s:~$ cat /proc/cpuinfo | grep nx
