15 | If you want to use a SCSI hard disk, SCSI tape drive, SCSI CD-ROM or | |
16 | any other SCSI device under Linux, say Y and make sure that you know | |
17 | the name of your SCSI host adapter (the card inside your computer | |
18 | that "speaks" the SCSI protocol, also called SCSI controller), | |
19 | because you will be asked for it. | |
20 | ||
21 | You also need to say Y here if you have a device which speaks | |
22 | the SCSI protocol. Examples of this include the parallel port | |

150 | directly, so you need some additional software which knows how to | |
151 | talk to these devices using the SCSI protocol: | |
152 | ||
153 | For scanners, look at SANE (<http://www.mostang.com/sane/>). For CD | |
154 | writer software look at Cdrtools | |
155 | (<http://www.fokus.gmd.de/research/cc/glone/employees/joerg.schilling/private/cdrecord.html>) | |

222 | ||
223 | If you say Y here, no logging output will appear by default, but you | |
224 | can enable logging by saying Y to "/proc file system support" and | |

230 | and logging level for each type of logging selected. | |
1da177e4 | 231 | |
5ef07416 RL |
232 | There are a number of logging types and you can find them in the |
233 | source at <file:drivers/scsi/scsi_logging.h>. The logging levels | |

485 | WARNING This driver is an older aic7xxx driver and is no longer | |
486 | under active development. Adaptec, Inc. is writing a new driver to | |
487 | take the place of this one, and it is recommended that whenever | |
488 | possible, people should use the new Adaptec written driver instead | |
489 | of this one. This driver will eventually be phased out entirely. | |
490 | ||
491 | This is support for the various aic7xxx based Adaptec SCSI | |
492 | controllers. These include the 274x EISA cards; 284x VLB cards; | |
493 | 2902, 2910, 293x, 294x, 394x, 3985 and several other PCI and | |
494 | motherboard based SCSI controllers from Adaptec. It does not support | |
495 | the AAA-13x RAID controllers from Adaptec, nor will it likely ever | |
496 | support them. It does not support the 2920 cards from Adaptec that | |
497 | use the Future Domain SCSI controller chip. For those cards, you | |
498 | need the "Future Domain 16xx SCSI support" driver. | |
499 | ||
500 | In general, if the controller is based on an Adaptec SCSI controller | |
501 | chip from the aic777x series or the aic78xx series, this driver | |
502 | should work. The only exception is the 7810 which is specifically | |
503 | not supported (that's the RAID controller chip on the AAA-13x | |
504 | cards). | |
505 | ||
506 | Note that the AHA2920 SCSI host adapter is *not* supported by this | |
507 | driver; choose "Future Domain 16xx SCSI support" instead if you have | |
508 | one of those. | |

843 | If the adapter isn't found during boot (a common problem for models | |
844 | 56, 57, 76, and 77) you'll need to use the 'ibmmcascsi=<pun>' kernel | |

846 | if that doesn't work check your reference diskette). Owners of | |

858 | depends on SCSI_IBMMCA | |
859 | ---help--- | |
860 | In the PC-world and in most modern SCSI-BIOS-setups, SCSI-hard disks | |
861 | are assigned to the drive letters, starting with the lowest SCSI-id | |
862 | (physical number -- pun) to be drive C:, as seen from DOS and | |
863 | similar operating systems. When looking into papers describing the | |
864 | ANSI-SCSI-standard, this assignment of drives appears to be wrong. | |
865 | The SCSI-standard follows a hardware-hierarchy which says that id 7 | |
866 | has the highest priority and id 0 the lowest. Therefore, the host | |
867 | adapters are still today everywhere placed as SCSI-id 7 by default. | |
868 | In the SCSI-standard, the drive letters express the priority of the | |
869 | disk. C: should be the hard disk, or a partition on it, with the | |
870 | highest priority. This must therefore be the disk with the highest | |
871 | SCSI-id (e.g. 6) and not the one with the lowest! IBM-BIOS kept the | |
872 | original definition of the SCSI-standard as also industrial- and | |
873 | process-control-machines, like VME-CPUs running under realtime-OSes | |
874 | (e.g. LynxOS, OS9) do. | |
875 | ||
876 | If you like to run Linux on your MCA-machine with the same | |
877 | assignment of hard disks as seen from e.g. DOS or OS/2 on your | |
878 | machine, which is in addition conformant to the SCSI-standard, you | |
879 | must say Y here. This is also necessary for MCA-Linux users who want | |
880 | to keep downward compatibility to older releases of the | |
881 | IBM-MCA-SCSI-driver (older than driver-release 2.00 and older than | |
882 | June 1997). | |
883 | ||
884 | If you like to have the lowest SCSI-id assigned as drive C:, as | |
885 | modern SCSI-BIOSes do, which does not conform to the standard, but | |
886 | is widespread and common in the PC-world of today, you must say N | |
887 | here. If unsure, say Y. | |

893 | By default, SCSI-devices are reset when the machine is powered on. | |
894 | However, some devices exist, like special-control-devices, | |
895 | SCSI-CNC-machines, SCSI-printer or scanners of older type, that do | |
896 | not reset when switched on. If you say Y here, each device connected | |
897 | to your SCSI-bus will be issued a reset-command after it has been | |
898 | probed, while the kernel is booting. This may cause problems with | |
899 | more modern devices, like hard disks, which do not appreciate these | |
900 | reset commands, and can cause your system to hang. So say Y only if | |

1240 | This is a driver for the MicroChannel Quad 720 card produced by | |

1242 | tries to negotiate sync and uses tag command queueing. | |

1250 | default "8" | |
1251 | ---help--- | |
1252 | "Tagged command queuing" is a feature of SCSI-2 which improves | |
1253 | performance: the host adapter can send several SCSI commands to a | |
1254 | device's queue even if previous commands haven't finished yet. | |
1255 | Because the device is intelligent, it can optimize its operations | |
1256 | (like head positioning) based on its own request queue. Some SCSI | |
1257 | devices don't implement this properly; if you want to disable this | |
1258 | feature, enter 0 or 1 here (it doesn't matter which). | |
1259 | ||
1260 | The default value is 8 and should be supported by most hard disks. | |
1261 | This value can be overridden from the boot command line using the | |
1262 | 'tags' option as follows (example): | |
1263 | 'ncr53c8xx=tags:4/t2t3q16/t0u2q10' will set default queue depth to | |
1264 | 4, set queue depth to 16 for target 2 and target 3 on controller 0 | |
1265 | and set queue depth to 10 for target 0 / lun 2 on controller 1. | |
1266 | ||
1267 | The normal answer therefore is to go with the default 8 and to use | |
1268 | a boot command line option for devices that need to use a different | |
1269 | command queue depth. | |
1270 | ||
1271 | There is no safe option other than using good SCSI devices. | |

1278 | This option allows you to specify the maximum number of commands | |
1279 | that can be queued to any device, when tagged command queuing is | |
1280 | possible. The default value is 32. Minimum is 2, maximum is 64. | |
1281 | Modern hard disks are able to support 64 tags and even more, but | |
1282 | do not seem to be faster when more than 32 tags are being used. | |
1283 | ||
1284 | So, the normal answer here is to go with the default value 32 unless | |
1285 | you are using very large hard disks with large cache (>= 1 MB) that | |
1286 | are able to take advantage of more than 32 tagged commands. | |
1287 | ||
1288 | There is no safe option and the default answer is recommended. | |

1294 | ---help--- | |
1295 | The SCSI Parallel Interface-2 Standard defines 5 classes of transfer | |
1296 | rates: FAST-5, FAST-10, FAST-20, FAST-40 and FAST-80. The numbers | |
1297 | are respectively the maximum data transfer rates in mega-transfers | |
1298 | per second for each class. For example, a FAST-20 Wide 16 device is | |
1299 | able to transfer data at 20 million 16 bit packets per second for a | |
1300 | total rate of 40 MB/s. | |
1301 | ||
1302 | You may specify 0 if you want to only use asynchronous data | |
1303 | transfers. This is the safest and slowest option. Otherwise, specify | |
1304 | a value between 5 and 80, depending on the capability of your SCSI | |
1305 | controller. The higher the number, the faster the data transfer. | |
1306 | Note that 80 should normally be ok since the driver decreases the | |
1307 | value automatically according to the controller's capabilities. | |
1308 | ||
1309 | Your answer to this question is ignored for controllers with NVRAM, | |
1310 | since the driver will get this information from the user set-up. It | |
1311 | also can be overridden using a boot setup option, as follows | |
1312 | (example): 'ncr53c8xx=sync:12' will allow the driver to negotiate | |
1313 | for FAST-20 synchronous data transfer (20 mega-transfers per | |
1314 | second). | |
1315 | ||
1316 | The normal answer therefore is not to go with the default but to | |
1317 | select the maximum value 80 allowing the driver to use the maximum | |
1318 | value supported by each controller. If this causes problems with | |
1319 | your SCSI devices, you should come back and decrease the value. | |
1320 | ||
1321 | There is no safe option other than using good cabling, right | |
1322 | terminations and SCSI conformant devices. | |
