The above indicates a problem with the console driver properly attaching
to the grf driver.  Kinda strange, actually.  Did you select the 
"Video hack for P475" option in the Booter's booting dialog box?

The ite is the internal console.  The reason cannot start X _might_ be
related to this.  What kind of error messages do you get when you try
to start X?

This seem like a SCSI driver problem.  Allen Briggs might know more.

The 1.3 release kernel was #56, I think.  I don't know what -current
kernels at up to right now, and I wouldn't recommend running -current
at the moment, either.

UTSL (use the source, luke :-)  The best place to look is unfortunately
the source itself.  We don't have much in the way of documentation of
kernel data structures.  The section 9 man pages may be of some help,
as a book titled The Design and Implementation of the 4.4BSD Operating
System.

Do you mean which ones are used on the MacOS side?  None, really.

The people who maintain the MacOS utilities usually use either
CodeWarrior or Think C, but I don't know of any kernel development
that is really done on the MacOS side.

I hope this helps some.

Later.
