What is CoreView?
-----------------

CoreView is a small but fast memory viewer. With help of CoreView you
may look through the memory of your computer. CoreView also has
facilities for searching memory for specific strings or BIOS
extensions.

CoreView is particular a great tool if you are going to install new
hardware in your computer. Often you have to set jumbers on the add-on
card to install its BIOS into the right address space. But WHAT is the
right address space? With CoreView you may browse through ROM at C000h
thru F000h and look for empty slots.

CoreView is also capable of viewing memory in real time. What do we
mean with that? You may enable a function we call "timed display".
While this function is on, CoreView continously updates the screen with
data from memory. If any bits change, you will see it immediately on
the screen.


Q quick tour through the CoreView functions
-------------------------------------------

CoreView has many functions. As all functions are easy to use, we will
only use little space to explain them. You may call the help screen
inside CoreView by hitting Alt-H from the main screen. This help
screen summarises most of the functions.

First of all you may scroll through memory. To do this, you use the
arrow keys, Home, End etc. All PCs are capable of addressing at least
1 Mb of memory. With CoreView you may inspect this 1 Mb address space.
By using the arrow keys, PgUp, PgDn, Home, End and many control keys,
you may browse through this 1 Mb address space. At the bottom of the
PC memory there is always RAM installed. When you go to higher
addresses, the PC has ROM installed. RAM is memory which may be
changed by the CPU. ROM is Read Only memory, which means it may NOT be
changed. If CoreView encounters a ROM area, you will see a star (*)
right after the address. This star tells you, that you are currently
looking at ROM locations.

If you are using a colour monitor, you may have noticed that some bytes
are high-lighted while others aren't. All standard figures and letters
are shown in a bright colour by CoreView to make it easier for you to
recognize human-readable strings.

If you want to search for a specific string, you may do that. Hit
Alt-S to enter the search input screen. Enter the string you want to
search for. In the upper input window you may enter all characters
between 20h and FFh. If you also need to search any of the control
characters, you should hit the Tab key once, and enter the characters
as two-digit hex numbers. Hit Enter to begin the search or hit Esc to
abort.

You may choose to search for an exact match, or you may search for a
match, which is case-insensitive, eg. upper- and lowercase letters are
treated equal. Use Alt-C in the main screen to change the search case.

If CoreView finds your search string, and you want to repeat the search
for the next copy, then hit Alt-R to repeat.

CoreView displays a search message in the lower right corner of the
screen, while it's searching. The actual search is NOT interruptable.
On 386s a 1 Mb search takes approximately 2 seconds. On XTs and other
relatively slow computers, the search may take 15 seconds or more to
finish.

If you want to jump to a total different address, you may enter it into
the address window. When you hit Enter, CoreView is set to this new
address. You may also pick up the current address you are looking at,
and put it into the input box. Hit Ctrl-Enter to read the address from
the current window position. If you want to normalize this address,
just hit Alt-N. What do we mean with 'normalized address'? A
normalized address, is an address with an offset part always in the
range 0000 thru 000Fh.

CoreView provides you with two functions to specify how data are shown.
If you press Alt-W memory is displayed in wide format. This allows you
to see more data on a single screen. To switch back to the standard
hex display, hit Alt-W once more. Alt-A acts as a filter. If you
press Alt-A (ASCII), only ASCII characters are displayed. This filter
is useful when you are looking into text strings and don't want the
code displayed. Most code contains opcodes outside the ASCII range.
