hd=dtc2278

If you have a DTC2278D IDE interface this option

causes the driver to attempt to enable the second

controller as well as faster transfer options.

hd=noprobe

If the machine has an old IDE drive that suffers from

being probed this option will keep that disaster from

happening. For example, if the drive is hdb then the

following will allow the drive to not be probed but also

provide the drive information for proper identification of

the drive: hdb=noprobe hdb=1166,7,17 will do the trick.

hd=nowerr

As some drives appear to have the WRERR STAT bit

permanently stuck, this option allows the drive to work

anyway.

hd=cdrom

If there is an ATAPI compatible CD ROM installed on

one of the IDE controllers and it is not recognized by

the kernel, this option will allow the kernel to recognize

the drive.

xd=type,irq,iobase,dma chan

If the system has an old 8 bit xt card, the driver probes

the card for a BIOS. If none is found, or the sig 

nature is not recognized, then the drive will not be

recognized. This option will allow the recognition to

occur. type specifies the card manufacturer and has

the values: 0=generic; 1=DTC; 2,3,4=Western Digital;

5,6,7=Seagate; 8=OMTI. irq, iobase and dma chan

are all required parameters, so don't leave any of them

unspecified.
