Yeah, I must be getting blind in my dotage. I sure missed it. :(

> Either of the ll* drivers that suits his hardware.  The sh_tc3.dd is a

> "bank" is just over 80 megabytes. One could do it, but I've had no
> urge to...  Shortage of round tuits I guess.

> HOWEVER!!!!  Before formatting /sh when running nitros9, read the super
> descriptor docs very very, did I mention VERY CAREFULLY as there is a 1
> bit flag in one of the dmode accessible descriptor variables that tells
> format when it is to use the values specified in the sh_tc3.dd
> descriptor, or to query the drive for its capacity.  And if its not
> set correctly in the descriptor, it will very nonchalantly format the
> whole drive, which is NOT of course what you intended.  See the docs
> PLEASE.  Download the latest version from cloud9north.com/support,
> print it and stick it in the cubby hole next to your monitor for

> Missing from your list I see, is a ddi0_ide.dd which gives the ide user
> a /dd drive which could be either the master or the slave drive on the
> controller respectively.  Master or slave likely controllable by a
> dmode setting. read the docs.  Then read them 3 or 4 more times.  They
> are concise and many times interdependent.

> ddsd0_cocosdc.dd
> sd0_cocosdc.dd
> sd1_cocosdc.dd

> llcocosdc.dr
