0

- if CF card was detected and successfully initialized 

- 

1

- if FAT16 boot sector was not found 

- 

255

- if card was not detected 

Initializes CF card, reads CF FAT16 boot sector and extracts data needed by
the library.

Nothing.

function Cf_Fat_QuickFormat(var cf_fat_label : string[11]) :
byte;

- 

0

- if CF card was detected, successfully formated and initialized

- if FAT16 format was unseccessful 

- 

255

- if card was not detected 

Formats to FAT16 and initializes CF card.

Parameters : 

- 

cf_fat_label

: volume label (11 characters in length). If less than 11 charac

ters are provided, the label will be padded with spaces. If an empty string is 
passed, the volume will not be labeled. 

Note: This routine can be used instead or in conjunction with the Cf_Fat_Init routine.

Note: If CF card already contains a valid boot sector, it will remain unchanged
(except volume label field) and only FAT and ROOT tables will be erased. Also,
the new volume label will be set.

Nothing.
