Dear Mark,

Thanks for your reply ;-)

I can remove the kernel module and force the kernel to "delete" the  
device with something like:

# echo 1 > /sys/block/sdb/device/delete

But still PERC adapter will be available:

# lspci | grep -i lsi
04:04.0 SCSI storage controller: LSI Logic / Symbios Logic 53c1030  
PCI-X Fusion-MPT Dual Ultra320 SCSI (rev 08)

I want to disable completely the card.. perhaps there's a utility to  
manage BIOS system's from a running Linux box.

Regards,
