Forcing IDE to work in PIO mode

Forcing IDE to work in PIO mode

[Muruga Ganapathy]

Hello, 

How do I force the IDE to work in the PIO mode by including the 
option like "hdb=noprobe" in the setup.c?


My kernel version is 2.6.6

Thanks

Hello !

I would have thought "ide=nodma" at the command line would have worked

Thanks

Thanks Manish for the information.  
 
BTW, do you have patch to make the swarm IDE work in 2.6.6-rc3

I had posted a patch to this mailing list a few days back. The patch 
applies cleanly to the current tree and is currently checked in: 
drivers/ide/mips/swarm.c

Using this patch, Broadcom SWARM IDE works well

Thanks

[Muruga Ganapathy]

Manish, 

Thanks for the pointer.

I am looking for the PCMCIA-IDE driver for the SWARM board in 2.6.x
I did see this driver in 2.4.26/27 but not in 2.6.10.

Do you have any suggestions on porting the PCMCIA-IDE driver from 2.4.27
to 2.6.x?

Regards
G.Muruganandam

Please point me to the 2.4.26 or 2.4.27 code that you are referring to

Re: Forcing IDE to work in PIO mode

[Manish Lachwani]

The pcmcia support for the SWARM is provided by 
drivers/pcmcia/sibyte_generic.c in 2.4.26

This file (and may be others it depends on) does not exist in 2.6

Thanks
