XXX: Linux driver has a hack not to probe the slave drive. We just
create a phantom drive:
wdc0 at pcmcia0 function 0: < , Memory Card Adapter II, V1.00>
wdc0: i/o mapped mode
atabus2 at wdc0 channel 0
wd1 at atabus2 drive 0: <Memory Card Adapter II>
wd1: drive supports 1-sector PIO transfers, LBA addressing
wd1: 241 MB, 965 cyl, 16 head, 32 sec, 512 bytes/sect x 494080 sectors
wd2 at atabus2 drive 1: <>
wd2: drive supports 1-sector PIO transfers, chs addressing
wd2: 0, 0 cyl, 0 head, 0 sec, 512 bytes/sect x 0 sectors
wd2: 32-bit data port
wd2: disk label read failed
wd2: disk label read failed
