int scsi_partsize(unsigned char * buf, unsigned long capacity, unsigned int * cyls, unsigned int * hds, unsigned int * secs);
buf

capacity
size of the disk in sectors
cyls
put cylinders here
hds
put heads here
secs
put sectors here
determine the BIOS mapping/geometry used to create the partition table, storing the results in *cyls, *hds, and *secs
-1 on failure, 0 on success.
