As far as I know Borland TURBO C does not use int 21.1c for anything in
absread() / abswrite(). You have to find out whether "> 32 MB" access
style is needed YOURSELF.
int readbig(Word drive, Dword which, Byte near * buffer)
{
struct bigdisk buffer2;
buffer2.count = 1;
buffer2.sector = which;
buffer2.buffer = (Byte far *)buffer;
return absread(drive, 1, -1, (void *)&buffer2);
}
struct bigdisk /* WARNING: Must not be padded for alignment by the compiler */
{
Dword sector;
Word count;
Byte far *buffer;
};
This is how you would read > 32 MB in TURBO C...
Of course there is no FAT32 disk I/O support at all in Turbo C :-).
