24. INT 13H, Disk Handler

Use

Disk drive control and I/O. MP2500 supports two ATA drives and as
standard is supplied fitted with one, an internal CompactFlash device
configured as drive C.
MP2500 also supports a diskette drive - a H
connected to COM2, accessed as drive B. A PC's drive A can also be
accessed by using comms and the ORACLE or INTERLINK utility, as
described in Part 2 (see Chapter 10, Utilities). (Note that the H
GT disk drive is no longer available.)

Entry

parameters, as follows.
