$ man bootparam
   The 'hd=cyls,heads,sects[,wpcom[,irq]]' options
       These options are used to specify the physical geometry  of  the  disk.
       Only  the  first  three  values are required. The cylinder/head/sectors
       values will be those used by fdisk.  The write precompensation value is
       ignored  for  IDE  disks.  The IRQ value specified will be the IRQ used
       for the interface that the drive resides on, and is not really a  drive
       specific parameter.
  [...]
   The 'hd=noprobe' option
       Do not probe for this drive. For example,
 
              hdb=noprobe hdb=1166,7,17
 
       would  disable  the probe, but still specify the drive geometry so that
       it would be registered as a valid block device, and hence usable.


I don't know if this is useful but hope it's help. Try to set the same
values as the BIOS.
