Tips & Hints about ICP controllers and other peripherals
========================================================

Tagged queues and Fujitsu M 26xx harddisks
------------------------------------------
Fujitsu Harddisks of the M26XX series do not support the SCSI-II
feature tagged queues. You should disable this feature in the
initialize disks menue of the GDTSetup program. An inquiry command
shows, that the harddisk supports tagged queues (this is why you can
enable it in the GDTSetup) but this is not true as stated by Fujitsu
Germany.
