10.5.6 install works but hangs at login stage

[PixelJam]

This is really weird. I haven't seen any other similar posts.

 

Installed 10.5.6 using BOOT132, 10.5.6 Retail DVD, and UInstaller on...

 

HP xw8400, 2x2x2.6Ghz Xeon

 

It hangs on startup just at the point when the desktop appears and the Menu icons are being loaded up.

However, if I boot using the the BOOT132 disk then choose the Hard drive manually it works absolutely fine!

It will boot into safe mode just fine too, without using the BOOT132 disk.

 

Could this be a conflict between Chameleon and a system extension? Does booting off the BOOT132 disk mean loading a different version of Chameleon? I'm really stumped on this and would really appreciate some help.

 

Thanks!
