Again, unless you have documentation to tell Adaptec AIC-786x how to interpret these numbers, then it is totally useless. This is a bit mask variable that applies for up to 8 aic7xxx SCSI channels.

Furthermore, due to the current Ultra2 Adaptec AIC-786x designs, these bits are tied together such that setting either bit enables both low and high byte LVD termination. It is not possible to only set high or low byte LVD termination in this manner.


For other controllers, the only important bits are the two lowest bits. Setting the higher bits on non-Ultra2 controllers has no effect.


A few examples of how to use this option: It really shouldn't be used except in dire circumstances, and if that happens, I'm probably going to be telling you what to set this to anyway: Of course, if the proper setting was 0, then that's what it would be after the reset, but if the proper setting is actually Now, since we can't detect this at all, I've added this option to force the setting. If you have a BIOS on your controller then you should never need to use this option. However, if you are having lots of SCSI reset Adaptec AIC-786x and can't seem to get them knocked out, this may help.

Make a boot floppy that you can use to boot your computer up and that will detect the aic7xxx controller. Adaptec AIC-786x, power down your computer.

Next, boot up the floppy you made and wait for it to detect the aic7xxx controller. If Adaptec AIC-786x kernel finds the controller fine, says scsi: If this happens, then you next need to figure out what your settings Adaptec AIC-786x be. Record the initial DEVCONFIG values for each of your aic7xxx controllers as they are listed, and also record what the machine is detecting as the proper termination on your controllers.

The above option and this option both work on the order of the SCSI controllers as they are registered, so make sure you match the right DEVCONFIG values with the right controllers if you have more than one aic7xxx controller. Hopefully, that part is correct, but it could possibly be wrong if there is bogus cable detection logic on your controller or something similar. If it's an odd number, then the correct setting for that controller is 1. For any other controllers that didn't have an infinite reset problem, then reverse the above options. Bit 0 is for the first aic7xxx controller, bit 1 for the next, Adaptec AIC-786x.


Put all Adaptec AIC-786x bits together and you get a number. For example, if the third aic7xxx needed a 1, but the second and first both needed a 0, then the bits would be in binary.

This then translates to 0x This is fairly standard binary to hexadecimal conversions here. As of driver version 5. The param line is parsed in the following manner: Inside of a set of device entries, this moves us to the next device on the list. Outside of device entries, this moves us to the next host adapter It will set scsi id 0 to a queue depth of 8, id 1 to 12, leave id 2 at the default, set id 3 to tagged queueing enabled and use the default queue depth, id 4 default, id 5 disabled, and id 6 to 4. Fourth adapter, id 3 Adaptec AIC-786x disabled. Notice that leading commas simply increment what the first number effects, and there are no Adaptec AIC-786x for trailing commas.

When you close out an adapter, or the entire entry, anything not explicitly set stays at the default value. The scanner I used for this isn't perfect or highly robust.

If you mess the line up, the worst that should happen is that the line will get ignored. If you don't close out the entire entry with the final bracket, then any Adaptec AIC-786x aic7xxx options after this will get ignored.

So, in general, be sure of what you are entering, and after you have it right, just Adaptec AIC-786x it to Adaptec AIC-786x lilo. You can use that to verify that your options were parsed correctly. For example, the following is valid: However, the syntax to specify the options changes slightly.
