I have had multiple problems trying to install XP Pro SP2 on my Mac Pro using Boot Camp 1.1.2. First time I tried to install it gave me the hal.dll error. From there I formatted the drive again and reinstalled. All went great until I got to the second install screen. From there all the way into windows desktop the display would only show 4bit color @ 640x480. Even after running the Boot Camp drivers CD still wouldn't change display settings. Formatted and Re-installed again. Into the second install screen (the one where you put the CD-Key etc) it would just keep BSODing me with a IRQL_NO_EQUAL_etc etc. Specs: Mac Pro Quad 2.66Ghz ATI X1900 XT 1GB Dell 2005FPW 20" LCD Any ideas anyone?
