PDC 20276 RAID support in 2.4.18

Arjan and others,

I have added support for the PDC 20276 used on Gigabyte GA-8IHXP (and 
possibly other motherboards) to the ATARAID feature of the linux 2.4.18 
kernel.  I have tested that the pdcraid.c code works with this device.

I suspect you can drive this patch into the mainline kernel, but if you 
know of a better person, please advise.

Thanks!

What's wrong with the PDC 20276 support in the 2.4.19preX and rc kernels?

Best regards,

hi ya steve

how was the system tested ???

-- my simple raid-compatibility test is:
	( assuming raid1 or raid5 setup on ide disks )

- pull out /dev/hda
	- see if it boots

- pull out /dev/hdc  ( the other boot disk )
	- see if it boots

- plug a virgin ( unformatted/unpartitioned disk )
  into either /dev/hda or /dev/hdc
	- see if it boots and resyncs itself

if the system doesnt boot or doesnt resync ( all by itself )
than i'd see its a problem and need more fixing... and tweeking

- i disable all onboard ( motherboard/firmware based raid )

have fun
alvin

the pdc 202xx series chips are great for sw raid5...
( inexpensive, functional and works in the promise/maxtor pci cards )
