CARD SELECTION
The Card List box displays the cards currently supported by the PCMSCD
database. Cards are referenced by their ID string. When a card is
inserted, PCMSCD tries to match the CIS ID string of that card to the
ID string of one of the cards in the database. When a match is found,
the data for the identified card is used to configure the card.
When you select a card from the list, you will be presented with that
card's data, which you can edit if you wish. If you select NEW CARD,
you will be asked to indicate what resources will be used by the card,
and then you can fill in the parameters.
The entire Card List may not be visible; use the arrows if necessary.
There is room for twelve New Cards in this version of PCMSCD.EXE.
Please note that if the New Card requires more than simple enabling
of resources (Memory, IO, IRQ), a more complex driver may be necessary.

EDIT PARAMETERS
This screen is used to view, enter, or modify the parameters of the
chosen card. These parameters can be obtained from the card's
documentation or from the CIS of the card. Future versions of SCDEDIT
will register with Card Services and make the entry of this data easier.
Memory Windows and IO Address Windows each require three fields: Base,
Size, and Path Width.
The Memory Window Base is a two-digit hex number that represents the
upper nibble of the segment address of where the window starts.
The Memory Window Size is a two-digit decimal number which represents
the number of 4K blocks to use at the Window Base. The maximum value
is 16, or 64K.
The Memory Window Path width can be toggled between 8 and 16 bits.
The IO Window Base is a three-digit hex number that represents the
beginning port address of where the IO Window starts.
The IO Window Size is a two-digit decimal number which represents the
number of consecutive ports to use at the IO Base.
The IO Window Path width can be toggled between 8 and 16 bits.
The Card IRQ is the IRQ the PCMCIA card uses to notify its driver.
The Major and Minor Version Numbers must match those found in the ID
String of the PCMCIA card's CIS. They are two-digit hexadecimal.
The Option and Status Registers tell the PCMCIA card to internally
use a particular setup. These values must match those found in the
CIS corresponding to setup you wish to use. Note: Some cards may not
require the Status Register.
With the Card Status field it is possible to disable the card's
database entry. PCMSCD will bypass this card when searching the
database.
.3
ID STRING COMPILATION
ID Strings are what PCMSCD uses to differentiate one card from another.
These strings are found in the CIS of the PCMCIA card, in the VERS_1
tuple. The format of the CIS string is as follows: The first byte is
the Major Version Number, the next is the Minor Version Number.
Next comes a series of ASCIIZ strings. It is these strings that should
be entered into the ID fields.
These fields are 35 bytes wide. The zero terminators of the strings
will be supplied by SCDEDIT.

CREATE NEW CARD
With this screen it is possible to select the resources to be used by
the New Card. The Status Register is not necessary on all cards, refer
to the New Card's documentation.
All cards have the Option Register and ID Strings so these choices do
not appear in the list.
