21 | If you want to use a SCSI hard disk, SCSI tape drive, SCSI CD-ROM or | |
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), | |
25 | because you will be asked for it. | |
26 | ||
27 | You also need to say Y here if you have a device which speaks | |
28 | the SCSI protocol. Examples of this include the parallel port | |
29 | version of the IOMEGA ZIP drive, USB storage devices, Fibre | |
93c164af | 30 | Channel, and FireWire storage. |

631dd1a8 | 162 | For scanners, look at SANE (<http://www.sane-project.org/>). For CD |

225 | and logging level for each type of logging selected. | |

227 | There are a number of logging types and you can find them in the |
228 | source at <file:drivers/scsi/scsi_logging.h>. The logging levels | |

317 | combines with the host's TCP/IP stack, network drivers, and Network | |

1156 | ---help--- | |
1157 | "Tagged command queuing" is a feature of SCSI-2 which improves | |
1158 | performance: the host adapter can send several SCSI commands to a | |
1159 | device's queue even if previous commands haven't finished yet. | |
1160 | Because the device is intelligent, it can optimize its operations | |
1161 | (like head positioning) based on its own request queue. Some SCSI | |
1162 | devices don't implement this properly; if you want to disable this | |
1163 | feature, enter 0 or 1 here (it doesn't matter which). | |
1164 | ||
1165 | The default value is 8 and should be supported by most hard disks. | |
1166 | This value can be overridden from the boot command line using the | |
1167 | 'tags' option as follows (example): | |
1168 | 'ncr53c8xx=tags:4/t2t3q16/t0u2q10' will set default queue depth to | |
1169 | 4, set queue depth to 16 for target 2 and target 3 on controller 0 | |
1170 | and set queue depth to 10 for target 0 / lun 2 on controller 1. | |
1171 | ||
1172 | The normal answer therefore is to go with the default 8 and to use | |
1173 | a boot command line option for devices that need to use a different | |
1174 | command queue depth. | |

1186 | Modern hard disks are able to support 64 tags and even more, but | |
1187 | do not seem to be faster when more than 32 tags are being used. | |
1188 | ||
1189 | So, the normal answer here is to go with the default value 32 unless | |
1190 | you are using very large hard disks with large cache (>= 1 MB) that | |
1191 | are able to take advantage of more than 32 tagged commands. | |

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

1607 | ---help--- |
1608 | If you have an Atari with built-in NCR5380 SCSI controller (TT, | |
1609 | Falcon, ...) say Y to get it supported. Of course also, if you have | |
1610 | a compatible SCSI controller (e.g. for Medusa). | |
1611 | ||
1612 | To compile this driver as a module, choose M here: the | |
1613 | module will be called atari_scsi. | |
1614 | ||
1615 | This driver supports both styles of NCR integration into the | |
1616 | system: the TT style (separate DMA), and the Falcon style (via | |
1617 | ST-DMA, replacing ACSI). It does NOT support other schemes, like | |
1618 | in the Hades (without DMA). | |

1623 | help | |
1624 | This option increases the delay after a SCSI arbitration to | |
1625 | accommodate some flaky Toshiba CD-ROM drives. Say Y if you intend to | |
1626 | use a Toshiba CD-ROM drive; otherwise, the option is not needed and | |
1627 | would impact performance a bit, so say N. | |

1632 | help | |
1633 | Reset the devices on your Atari whenever it boots. This makes the | |
1634 | boot process fractionally longer but may assist recovery from errors | |
1635 | that leave the devices with SCSI operations partway completed. | |
