correction..
"The configuration for AMI adapters is not automatically saved to disk",
the configuration is actually saved to Nvram and to the disk once you
save the configuration during setup.
When the raid bios screen comes up, does it show a logical drive present
If there is an array it should? If not..
When you go into the raid cards setup ctl-m, under view/add config, does
it show an array ? If it does not show at the bios screen, it actually
should not show up in the view/add, curious, if anything shows.
I would definitely get in touch with LSIlogic, they may have tools to
resurrect the array info. Email me directly.
