Hrmm.. on the 7248.. there were a set of magical passwords
that would unlock a
low-end debug mode.  The most common of which was
"eatabug".  The rest were FW
version dependant, and listed inside the firmware upgrade
instructions.

(firmware for most models is here:
ftp://ftp.software.ibm.com/rs6000/firmware/ )

Unfortunately yours isn't listed..  However.. a long time
ago I managed to
download full docs for your machine..  Google for these
filenames:

sg242581.pdf
sg244592_IBM_PC_&_ThinkPad_Power_Series.pdf

If you can't find them.. let me know and I'll send you the
ones I have.  I only
read them looking for hardware info.. so I skipped over
anything about
operation of the machine.


I do find it utterly bizzare that your machine thinks it has
a floppy drive
when none is present.  On my machine, when I powercycle it,
it recognizes new
hardware, and that hardware shows up in the firmware if
it's a recognized part.
Maybe they hardcoded it..  who knows... Normally I'd tell
you to yank the
battery and see if that resets it.. but I'm afraid it might
over-reset it and
your firmware might stop working.  Given there are no
replacement images, and
no floppy to load them with, I wouldn't risk it.

I actually have one of these and have pulled the main and
the two (IIRC)
backup batteries and haven't lost anything... I think.
I'll try on mine
later today.

(BTW, I am most grateful this is being worked on and would
love to test
anything)

Is yours also a model 860?  I think there is also a model
820.  If you have one
of those, could you boot the special kernel I made for
Thomas earlier in this
thread?

If it's an 860.. there is likely no need.. unless yours is
somehow different
(like if the firmware detects one of the PCMCIA cards, that
would be
super-interesting)


Right now I'm in the middle of roto-tilling a large chunk
of the prep code, so
I'm not in a position to build any test kernels for
anyone.. Once I get this
stuff straightened out and committed, I'll build you guys a
few test kernels
with PCMCIA devices.  If you could both send a list of what
PCMCIA cards you
own to the list.. I'll make a kernel with support for as
many as I can, and I'd
like to see some testing results from booting with those
cards, taking them
in/out, using them, etc.
