IBM microdrive

Hi,
I want to use a IBM microdrive as a slave on a PC-104 plus stack. As given
in the qdn support documentation I start the devb-eide driver with slave
functionality

devb-eide eide ioport=0x240,irq=0x04, slave &

ioport and irq are obtained from pin

but the devb-eide complains about ata_ccb error.
I read somewhere that this si a problem with DMA enabled, but I have not
enabled DMA. Any help would be appreciated

Thanks
Srikanth
