The text console driver uses the copper for scrolling much faster than
the blitter could possibly do.  There are a few places that it could
possibly make use of the blitter, but it doesn't yet.

The graphics screen driver supports essentially all the standard Amiga
modes.  The X server uses this driver, but currently uses only one
bitplane.

In other words, The X server will do 1024x800 on the A2024, or 704x480
with overscan on an NTSC monitor, or the standard 640 x 400 NTSC mode,
or the corresponding PAL, non-HIRES, and non-interlaced modes.  I'm
aware of only one notable omission:  the 31kHz 640x480 "productivity"
mode of the ECS.

Greetings...
 
I work for a Commodore Amiga dealer in New York City and we recently 
received the Amiga 3000UX.  Setting up the Unix was quite simple and
our manager had the great idea of putting it on display in the sales pit.
As you would guess, when we were not looking, an unknowing customer made the
system reboot without doing a proper shutdown.  When we tried to get the 
system running again we were greeted with a flurry of DUP errors when going
through the phase 1, 1b and 2 checks.  This was then greeted further with
the system rebooting.  
 
I know what your saying, "Just re-install the system with the tape drive!"
 
Well, we tried that, using the Boot and Root disks.  And we were greeted 
even further with the following:
 
s5mountroot VOP_OPEN error 30

PANIC: vfs_mountroot: cannot mount root: errno30
Backtrace: 7C38492 7C38626 7C389A4 7C55466 7C514AC 7C00044
Kernal Root PTR: 7D15800 User Root PTR:0

-----------
Ok, so does anyone have any ideas what is going on here?  The manuals have
*NO* reference to error numbers or what to do in case of an inproper 
shutdown, nor can I believe all this is happening  because of one customer
pressing the wrong buttons.  Please respond via email is you can be of
*ANY* assistance.  Thank you.
