- 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.
