The patch is for FD24 to FD38.

The patch changes some loading routines. The FD used to call $0144 to read
sectors, the patch changes it in BDOS-equivalents.
Here's a snippet from the old routine (disassembled from MAG-INIT.BIN):
#D27C:    LD    A,(#D325)
                OUT    (#FE),A
                LD    HL,(#D31F)
                LD    DE,(#D321)
                LD    BC,(#D323)
                XOR    A
                CALL    #0144
                LD    A,B
                CP    #00
                JP    NZ,#D27C    ;repeat if loading failed
                JP    #D24D

I hope this helps...

Greetz,

Arjan
