One of the big complaints is that bootloaders are limited when using int13h to accessing harddisks plugged into the controller booting from, making it impossible to assemble raid 4|5|6 array in this case. I want to know if this is a limitation imposed on grub2, or is it smart enough to access the disks on all controllers on the host. -- Daniel Reurich Centurion Computer Technology (2005) Ltd Ph 021 797 722
