In ide.h: #define INITIAL_MULT_COUNT 0
In ide-disk.c: drive->mult_req = INITIAL_MULT_COUNT;
However, for me this gives me (during idedisk_setup):
hda:hda: set_multmode: status=0x51 { DriveReady SeekComplete Error }
hda: set_multmode: error=0x04 { DriveStatusError }
so I set in ide.h #define INITIAL_MULT_COUNT 32
Alternatively, part of Andre Hedrick's ide_2_2_12_19990925 patch can be
used by doing the following:

drive->mult_req = INITIAL_MULT_COUNT;
if (drive->mult_req > id->max_multsect)

Is this unwise for me to do?
