=> R0 = reason code
Other registers varying according to reason code.
<= Dependant on reason code.
Supports splitting one physical drive into several logical drives.
SCSIFS_Partitions Reason Codes
Code Meaning
0 Set sector offset for partition
1 Lookup drive number for id
SCSIFS_Partitions 0
=> R0 = 0
R1 = SCSI ID
R2 = Sector offset to partition start
Should not be used after mounting the disc, otherwise loss of data is likely to occur.
SCSIFS_Partitions 1
=> R0 = 1
R1 = SCSI ID
<= R2 = SCSIFS drive number
