I have a Compaq Deskpro 3255MMX. IDE CD-ROM as originally supplied. After reading a magazine article, i went to properites of my CD-ROM and ticked the DMA box.
Now when i boot up the whole machine freezes just after drawing the icons on the desktop. If i disconnect the CD-ROM, no problems.
I've tried removing the device in My Computer, but no good.
I can't uncheck the box because the system freezes before i get a chance to open my computer.
I tried booting into Safe Mode and doing it there, but i then get a message saying unable to update registry.
How do i get my CD-ROM back?
