you need to modify linux/include/linux/libata.h and change

#undef ATA_ENABLE_ATAPI /* define to enable ATAPI support */
#undef ATA_ENABLE_PATA /* define to enable PATA support in some */

to

#define ATA_ENABLE_ATAPI /* define to enable ATAPI support */
#define ATA_ENABLE_PATA /* define to enable PATA support in some

for the 9300 atleastalso add ide1=noprobe to grub
