I have not yet tried it on the Ultimate 32 bit computer. but yes I tried it on other sata ports, because I have 2 of them in that machine. I even unpluged one and tried and then switched to a different sata port with just one drive.
I can put in a Ultimate Boot Cd and it reads the files and will boot to it. But lets say I make a bootable shage boot cd , or a bootable ntfs cd, it burns the disks, then after burn , you can not explore and see the files on it, says not cd inserted. won't boot to the cd either. yet it works fine or install and seeing vista cd, and UBCD. this other computer can see and do all of it.
Vista Ultimate computer is asus crosshair 6400+ amd . new one is MSI 790GX Platinum board with 9550 amd quad on it. both have 4 gig corsair xms ram.
well maybe someone that has this asus 20B1LT will try out making the bootables from .iso files and see if theirs works. even used magic iso program, same results.
