AMI FastDisk Host Adapters that are true BusLogic MultiMaster clones are also
The BusLogic Driver Probing Options comprise the following:
-IO:<integer>
-
- The "IO:" option specifies an ISA I/O Address to be probed for a non-PCI
- MultiMaster Host Adapter. If neither "IO:" nor "NoProbeISA" options are
- specified, then the standard list of BusLogic MultiMaster ISA I/O Addresses
- will be probed (0x330, 0x334, 0x230, 0x234, 0x130, and 0x134). Multiple
- "IO:" options may be specified to precisely determine the I/O Addresses to
- be probed, but the probe order will always follow the standard list.
-
NoProbe
The "NoProbe" option disables all probing and therefore no BusLogic Host
Adapters will be detected.
-NoProbeISA
-
- The "NoProbeISA" option disables probing of the standard BusLogic ISA I/O
- Addresses and therefore only PCI MultiMaster and FlashPoint Host Adapters
- will be detected.
-
NoProbePCI
The "NoProbePCI" options disables the interrogation of PCI Configuration
Depth for devices that do not support Tagged Queuing. If no Queue Depth
option is provided, the Queue Depth will be determined automatically based
on the Host Adapter's Total Queue Depth and the number, type, speed, and
- capabilities of the detected Target Devices. For Host Adapters that
- require ISA Bounce Buffers, the Queue Depth is automatically set by default
- to BusLogic_TaggedQueueDepthBB or BusLogic_UntaggedQueueDepthBB to avoid
- excessive preallocation of DMA Bounce Buffer memory. Target Devices that
+ capabilities of the detected Target Devices. Target Devices that
do not support Tagged Queuing always have their Queue Depth set to
BusLogic_UntaggedQueueDepth or BusLogic_UntaggedQueueDepthBB, unless a
lower Queue Depth option is provided. A Queue Depth of 1 automatically
