ok. so i updated to the new mac pro firmware (1.1) now I can install windows with my 23" ACD and X1900XT. Yay. Now onto a new problem. I installed Bootcamp 1.1.2 awhile back. Ran Bootcamp Assistant Setup a 32gig partition for XP. Restarted to start installation All loads fine until the partition selection screen. I select my 32 gigabyte partition to install XP onto. It tells me: "To install Windows XP on the partition you selected, Setup must write some startup files to the following disk:" Lists the 160gig drive ... "However, this disk does not contain a Windows XP-compatible partition." Seems the only way to get it to work is to delete the partition and install that way.. but that'll kill my OS X partition so not an option. Anyone run into this problem before? Seems I just can't get lucky at all with bootcamp.
