@CHIP-RTOS C Library - External Disk API
Header File: #include <EXTDISK.H>
Here is the CLIB API for an external disk B: and D: drive.
This interface allows you to add an external B: or D: drive. This drive must be
block (sector) oriented. Each sector should be 512 bytes long. The
application must provide a software interrupt 0xB1 function for drive B:
or 0xB2 for drive D: to read and write these sectors on this drive.
On SC1x systems, the maximum disk size is about 2 Gigabytes. (This
limitation is due to the FAT16 disk format used on SC1x systems.)
SC1x systems support only drive B:
The SC1x3/SC2x systems support FAT32 format. The maximum disk size
on SC1x3/SC2x systems is about 8 Terabytes.
The maximum file size is 2**32 bytes minus one cluster (=32 kbyte), which
is about 4 Gigabyte. SC1x3/SC2x systems support drive B: and drive D:.
