22 any other SCSI device under Linux, say Y and make sure that you know

507 WARNING This driver is an older aic7xxx driver and is no longer
508 under active development. Adaptec, Inc. is writing a new driver to
509 take the place of this one, and it is recommended that whenever
510 possible, people should use the new Adaptec written driver instead
511 of this one. This driver will eventually be phased out entirely.
512
513 This is support for the various aic7xxx based Adaptec SCSI
514 controllers. These include the 274x EISA cards; 284x VLB cards;
515 2902, 2910, 293x, 294x, 394x, 3985 and several other PCI and
516 motherboard based SCSI controllers from Adaptec. It does not support
517 the AAA-13x RAID controllers from Adaptec, nor will it likely ever
518 support them. It does not support the 2920 cards from Adaptec that
519 use the Future Domain SCSI controller chip. For those cards, you
520 need the "Future Domain 16xx SCSI support" driver.
521
522 In general, if the controller is based on an Adaptec SCSI controller
523 chip from the aic777x series or the aic78xx series, this driver
524 should work. The only exception is the 7810 which is specifically
525 not supported (that's the RAID controller chip on the AAA-13x
526 cards).
527
528 Note that the AHA2920 SCSI host adapter is *not* supported by this
529 driver; choose "Future Domain 16xx SCSI support" instead if you have
530 one of those.
531
532 Information on the configuration options for this controller can be
533 found by checking the help file for each of the available
534 configuration options. You should read
535 <file:Documentation/scsi/aic7xxx_old.txt> at a minimum before
536 contacting the maintainer with any questions. The SCSI-HOWTO,

1210 default "8"
1211 ---help---
1212 "Tagged command queuing" is a feature of SCSI-2 which improves
1213 performance: the host adapter can send several SCSI commands to a
1214 device's queue even if previous commands haven't finished yet.
1215 Because the device is intelligent, it can optimize its operations
1216 (like head positioning) based on its own request queue. Some SCSI
1217 devices don't implement this properly; if you want to disable this
1218 feature, enter 0 or 1 here (it doesn't matter which).
1219
1220 The default value is 8 and should be supported by most hard disks.
1221 This value can be overridden from the boot command line using the
1222 'tags' option as follows (example):
1223 'ncr53c8xx=tags:4/t2t3q16/t0u2q10' will set default queue depth to
1224 4, set queue depth to 16 for target 2 and target 3 on controller 0
1225 and set queue depth to 10 for target 0 / lun 2 on controller 1.
1226
1227 The normal answer therefore is to go with the default 8 and to use
1228 a boot command line option for devices that need to use a different
1229 command queue depth.
1230
1231 There is no safe option other than using good SCSI devices.

1241 Modern hard disks are able to support 64 tags and even more, but
1242 do not seem to be faster when more than 32 tags are being used.
1243
1244 So, the normal answer here is to go with the default value 32 unless
1245 you are using very large hard disks with large cache (>= 1 MB) that
1246 are able to take advantage of more than 32 tagged commands.
1247

1254 ---help---
1255 The SCSI Parallel Interface-2 Standard defines 5 classes of transfer
1256 rates: FAST-5, FAST-10, FAST-20, FAST-40 and FAST-80. The numbers
1257 are respectively the maximum data transfer rates in mega-transfers
1258 per second for each class. For example, a FAST-20 Wide 16 device is
1259 able to transfer data at 20 million 16 bit packets per second for a
1260 total rate of 40 MB/s.
1261
1262 You may specify 0 if you want to only use asynchronous data
1263 transfers. This is the safest and slowest option. Otherwise, specify
1264 a value between 5 and 80, depending on the capability of your SCSI
1265 controller. The higher the number, the faster the data transfer.
1266 Note that 80 should normally be ok since the driver decreases the
1267 value automatically according to the controller's capabilities.
1268
1269 Your answer to this question is ignored for controllers with NVRAM,
1270 since the driver will get this information from the user set-up. It
1271 also can be overridden using a boot setup option, as follows
1272 (example): 'ncr53c8xx=sync:12' will allow the driver to negotiate
1273 for FAST-20 synchronous data transfer (20 mega-transfers per
1274 second).
1275
1276 The normal answer therefore is not to go with the default but to
1277 select the maximum value 80 allowing the driver to use the maximum
1278 value supported by each controller. If this causes problems with
1279 your SCSI devices, you should come back and decrease the value.
1280
1281 There is no safe option other than using good cabling, right
1282 terminations and SCSI conformant devices.

1524 This is a host adapter simulator that can simulate multiple hosts
1525 each with multiple dummy SCSI devices (disks). It defaults to one
1526 host adapter with one dummy SCSI disk. Each dummy disk uses kernel
1527 RAM as storage (i.e. it is a ramdisk). To save space when multiple
1528 dummy disks are simulated, they share the same kernel RAM for

1551 drives a bus which is entirely internal to the machine (such as the

1554 controlled by the MESH can have external devices connected, it is
1555 usually rated at 5 MB/s. 5 is a safe value here unless you know the
