  21. the name of your SCSI host adapter (the card inside your computer
  22. that "speaks" the SCSI protocol, also called SCSI controller),
  23. because you will be asked for it.
  24. You also need to say Y here if you have a device which speaks

  98. tape drives (ADR-x0) that supports the standard SCSI-2 commands for
  99. tapes (QIC-157) and can be driven by the standard driver st.
  100. For more information, you may have a look at the SCSI-HOWTO
  101. <http://www.tldp.org/docs.html#howto> and

  134. CD-ROMs or tapes, say Y here. These won't be supported by the kernel
  135. directly, so you need some additional software which knows how to
  136. talk to these devices using the SCSI protocol:
  137. For scanners, look at SANE (<http://www.sane-project.org/>). For CD
  138. writer software look at Cdrtools
  139. (<http://cdrecord.berlios.de/private/cdrecord.html>)
  140. and for burning a "disk at once": CDRDAO
  141. (<http://cdrdao.sourceforge.net/>). Cdparanoia is a high
  142. quality digital reader of audio CDs (<http://www.xiph.org/paranoia/>).
  143. For other devices, it's possible that you'll have to write the
  144. driver software yourself. Please read the file

  947. ---help---
  948. "Tagged command queuing" is a feature of SCSI-2 which improves
  949. performance: the host adapter can send several SCSI commands to a
  950. device's queue even if previous commands haven't finished yet.
  951. Because the device is intelligent, it can optimize its operations
  952. (like head positioning) based on its own request queue. Some SCSI
  953. devices don't implement this properly; if you want to disable this
  954. feature, enter 0 or 1 here (it doesn't matter which).
  955. The default value is 8 and should be supported by most hard disks.
  956. This value can be overridden from the boot command line using the
  957. 'tags' option as follows (example):
  958. 'ncr53c8xx=tags:4/t2t3q16/t0u2q10' will set default queue depth to
  959. 4, set queue depth to 16 for target 2 and target 3 on controller 0
  960. and set queue depth to 10 for target 0 / lun 2 on controller 1.
  961. The normal answer therefore is to go with the default 8 and to use
  962. a boot command line option for devices that need to use a different
  963. command queue depth.
  964. There is no safe option other than using good SCSI devices.

  973. Modern hard disks are able to support 64 tags and even more, but
  974. do not seem to be faster when more than 32 tags are being used.
  975. So, the normal answer here is to go with the default value 32 unless
  976. you are using very large hard disks with large cache (>= 1 MB) that
  977. are able to take advantage of more than 32 tagged commands.

  984. The SCSI Parallel Interface-2 Standard defines 5 classes of transfer
  985. rates: FAST-5, FAST-10, FAST-20, FAST-40 and FAST-80. The numbers
  986. are respectively the maximum data transfer rates in mega-transfers
  987. per second for each class. For example, a FAST-20 Wide 16 device is
  988. able to transfer data at 20 million 16 bit packets per second for a
  989. total rate of 40 MB/s.
  990. You may specify 0 if you want to only use asynchronous data
  991. transfers. This is the safest and slowest option. Otherwise, specify
  992. a value between 5 and 80, depending on the capability of your SCSI
  993. controller. The higher the number, the faster the data transfer.
  994. Note that 80 should normally be ok since the driver decreases the
  995. value automatically according to the controller's capabilities.
  996. Your answer to this question is ignored for controllers with NVRAM,
  997. since the driver will get this information from the user set-up. It
  998. also can be overridden using a boot setup option, as follows
  999. (example): 'ncr53c8xx=sync:12' will allow the driver to negotiate
  1000. for FAST-20 synchronous data transfer (20 mega-transfers per
  1001. second).
  1002. The normal answer therefore is not to go with the default but to
  1003. select the maximum value 80 allowing the driver to use the maximum
  1004. value supported by each controller. If this causes problems with
  1005. your SCSI devices, you should come back and decrease the value.
