Define a constant for the SuperMac Spectrum/24 series III display card.
Thanks go to Luca Falzoni <falzoni@jetai.unipv.it> for trying out the
code for the Dayna ethernet support.
- it now tries to find out if there are files that look like install
sets in the remote directory.
- it is possible to change to another directory when there are no
things like install-sets around.
- you can even get a directory listing while trying to find the
correct directory (wow ;-)
- when the correct directory is found, you can tag the sets you want to
extract (like in all(?) other cases). The only difference is that the
get-install sequence is batched.
There is still plenty of room for improvement, but it's getting workable.
a function) which specifies how many lines will be skipped when scrolling
up when the bottom of the screen is reached. Dumb framebuffers skip 10
lines (as before) because the copies are s ... l ... o ... w, but it's
silly to skip 10 lines on VGA, since the copies are much faster, so we
only skip one in that case.
memory-mapped or i/o-mapped access to the device registers, and always
choose memory-mapped if it is enabled. In particular, do _not_ explictly
disable the space we decide to not use, as this confuses some versions
of Alpha console software (which are arguably buggy because of this
problem).
Also, fix a logic error pointed out by Ross Harvey <ross@teraflop.com>
that would cause memory-mapped access to never be enabled.
unmounting all of the file systems. If we encounter a condition where
all of the dirty buffers could not flush, then don't unmount file systems,
since it might be likely to wedge.
- MIT syntax to Motorola syntax moveml register lists (for better readability)
- comment alignment
- remove commented out debug or alternate code from early DraCo support
development.
(I wanted to do this stuff for a long time, but always had "more important"
things to do.)
