36 recently, BusLogic introduced the FlashPoint Host Adapters, which are less
37 costly and rely on the host CPU, rather than including an onboard processor.
38 Despite not having an onboard CPU, the FlashPoint Host Adapters perform very
39 well and have very low command latency. BusLogic has recently provided me with

43 analogous to the firmware on the MultiMaster Host Adapters. Thanks to their

157 is determined automatically based on the host adapter's total queue depth and
159 addition, tagged queuing is automatically disabled whenever the host adapter

343 In systems with multiple BusLogic PCI Host Adapters, the order in which the
344 PCI slots are scanned may appear reversed with the BT-948/958/958D as
345 compared to the BT-946C/956C/956CD. For booting from a SCSI disk to work
346 correctly, it is necessary that the host adapter's BIOS and the kernel agree
348 host adapters in the same order. The motherboard's PCI BIOS provides a
349 standard way of enumerating the PCI host adapters, which is used by the Linux
357 host adapter's BIOS to receive Windows 95 certification. Therefore, the
358 factory default settings of the BT-948/958/958D enumerate the host adapters
360 the AutoSCSI utility via Ctrl-B at system startup and select "Adapter
361 Configuration", "View/Modify Configuration", press Ctrl-F10, and then change

366 by the host adapter's BIOS.
