22 any other SCSI device under Linux, say Y and make sure that you know
23 the name of your SCSI host adapter (the card inside your computer
24 that "speaks" the SCSI protocol, also called SCSI controller),

28 the SCSI protocol. Examples of this include the parallel port

1154 default "8"
1155 ---help---
1156 "Tagged command queuing" is a feature of SCSI-2 which improves
1157 performance: the host adapter can send several SCSI commands to a
1158 device's queue even if previous commands haven't finished yet.
1159 Because the device is intelligent, it can optimize its operations
1160 (like head positioning) based on its own request queue. Some SCSI
1161 devices don't implement this properly; if you want to disable this
1162 feature, enter 0 or 1 here (it doesn't matter which).
1163
1164 The default value is 8 and should be supported by most hard disks.
1165 This value can be overridden from the boot command line using the
1166 'tags' option as follows (example):
1167 'ncr53c8xx=tags:4/t2t3q16/t0u2q10' will set default queue depth to
1168 4, set queue depth to 16 for target 2 and target 3 on controller 0
1169 and set queue depth to 10 for target 0 / lun 2 on controller 1.
1170
1171 The normal answer therefore is to go with the default 8 and to use
1172 a boot command line option for devices that need to use a different
1173 command queue depth.
1174
1175 There is no safe option other than using good SCSI devices.

1181 ---help---
1182 This option allows you to specify the maximum number of commands
1183 that can be queued to any device, when tagged command queuing is
1184 possible. The default value is 32. Minimum is 2, maximum is 64.
1185 Modern hard disks are able to support 64 tags and even more, but
1186 do not seem to be faster when more than 32 tags are being used.
1187
1188 So, the normal answer here is to go with the default value 32 unless
1189 you are using very large hard disks with large cache (>= 1 MB) that
1190 are able to take advantage of more than 32 tagged commands.
1191
1192 There is no safe option and the default answer is recommended.

1197 default "20"
1198 ---help---
1199 The SCSI Parallel Interface-2 Standard defines 5 classes of transfer
1200 rates: FAST-5, FAST-10, FAST-20, FAST-40 and FAST-80. The numbers
1201 are respectively the maximum data transfer rates in mega-transfers
1202 per second for each class. For example, a FAST-20 Wide 16 device is
1203 able to transfer data at 20 million 16 bit packets per second for a
1204 total rate of 40 MB/s.
1205
1206 You may specify 0 if you want to only use asynchronous data
1207 transfers. This is the safest and slowest option. Otherwise, specify
1208 a value between 5 and 80, depending on the capability of your SCSI
1209 controller. The higher the number, the faster the data transfer.
1210 Note that 80 should normally be ok since the driver decreases the
1211 value automatically according to the controller's capabilities.
1212
1213 Your answer to this question is ignored for controllers with NVRAM,
1214 since the driver will get this information from the user set-up. It
1215 also can be overridden using a boot setup option, as follows
1216 (example): 'ncr53c8xx=sync:12' will allow the driver to negotiate
1217 for FAST-20 synchronous data transfer (20 mega-transfers per
1218 second).
1219
1220 The normal answer therefore is not to go with the default but to
1221 select the maximum value 80 allowing the driver to use the maximum
1222 value supported by each controller. If this causes problems with
1223 your SCSI devices, you should come back and decrease the value.
1224
1225 There is no safe option other than using good cabling, right
1226 terminations and SCSI conformant devices.
