whats involved in making a DAC960 raid controller work with grub
attached is a patch to grub-install.in which converts the device to grub
syntax.
also attached is the DAC960's make_rd script which makes the devices.
this will show the syntax of the devices.
but as for grub itself, where would I start. I wonder if its over my
head.
Thanks.
