Folks,

I have updated the help for the Promise controller cards to match the code 
and provide a bit more information.

Enjoy.

Thanks Ruth.

I've taken your work and formatted it for the drivers/ide/Kconfig file
in 2.5. Here's the patch.

This was made against the current 2.5 tree.

This is probably okay.

I've seen this "up to 4 more EIDE devices sharing a single
interrupt" also in comments for HighPoint controllers...

I think all such comments are bogus.

I think this comment is highly specific to Ultra33 cards...

Also if you use this driver and choose to override BIOS you can probably
use as much cards as you want (currently driver limits it to 5,
but this is easy to change).

There is already confusion here, please don't make it worse ;-).

Ultra33? This is driver for new Promise controllers.

Please read recent "IDE/Promise 20276 FastTrack RAID..." thread.
Also ataraid driver is not ported to 2.5 yet.

The device names are taken from the driver source and where possible confirmed 
from the Promise web site (looking in BIOS files).

In this case I kept the old comments, as I wasn't sure that they were 
incorrect. I will have a go at rehashing this paragraph.

It is true that I have never needed it for either of the Ultra 100's I have, 
although having it enabled didn't seem to hurt.

As above, this is duplicated from the original help. So I'm not making things 
worse. That said I am hoping to make things better.

I will change it to make it clearer that the statements about Ultra33 are 
specific to Ultra33.
Are you telling me that I should change it to be unlimied # cards?

OOps... will fix.

I will: I hadn't noticed it.  [ looks ] So there is another patch for the  
(ugh!) 'special feature' -- do you want me to:
 - integrate that patch with mine & resubmit
 - take input from that patch into mine & resubmit
 - go away :-(

Does ataraid work well on 2.4? I have never used it as I have preferred the 
user-space tools available for Linux-raid. On 2.5 KConfig as ataraid doesn't 
work I guess the right thing is to always configure as non-raid, so not 
requiring a user-question and therefore no help.

I have updated my Configure.help patch in ways that I hope address your 
concerns above. I can see from Steven Drake's patch that I should also modify 
Config.in: should we continue I will do that & send a patch for it.

If we come to consensus on this patch I will update Steven's KConfig one also.

Promise binary drivers can be used in 2.5.

You don't. This patch looks (almost?) exactly as previous one.

You can always split your patch to get non-controversial parts accepted
first.  I will also try to correct this patch when I have some time.

Ok. I will carry on. In my reply to the thread you pointed me to, I have 
proposed some other choices.

The answer seems to be that people are happy with ataraid in 2.4, apart from 
Promise who would prefer it didn't exist :-)

It wasn't. This is what it looks like without 'diff' stuff around it. I have 
removed refs to Ultra33 in the new bit, and rewritten the main paras in both. 
However, as I said I did an alternative version in the other mail that you 
might prefer. However that didn't actually have as much information in it 
(e.g. stuff about using DMA by default, BIOS version problems):

PROMISE PDC20246/PDC20262/PDC20263/PDC20265/PDC20267 support
CONFIG_BLK_DEV_PDC202XX_OLD
  Promise Ultra 33 [PDC20246]
  Promise Ultra 66 [PDC20262]
  Promise FastTrak 66 [PDC20263]
  Promise MB Ultra 100 [PDC20265]
  Promise Ultra 100 [PDC20267]

  This driver adds support for the older series of Promise EIDE disk
  interface devices. Each device supports up to 4 disk drives that
  can use UDMA disk access (33MHz for Ultra 33 up to 100MHz for Ultra
  100).

  If multiple cards are installed you might have problems booting if
  the BIOS versions for the cards are different. Therefore the driver
  attempts to do dynamic tuning of the chipset at boot-time.

  If you are using an Ultra 33, BIOS version 1.25 or newer is required
  to support more than one card and you should say Y to "Special UDMA
  Feature" to force UDMA mode for connected UDMA capable disk drives.

  If you say Y here, you need to say Y to "Use DMA by default when
  available" as well.

  If unsure, say N.

PROMISE PDC202{68|69|70|71|75|76|77} support
CONFIG_BLK_DEV_PDC202XX_NEW
  Promise Ultra 100 TX2 [PDC20268]
  Promise Ultra 133 PTX2 [PDC20269]
  Promise FastTrak LP/TX2/TX4 [PDC20270]
  Promise FastTrak TX2000 [PDC20271]
  Promise MB Ultra 133 [PDC20275]
  Promise MB FastTrak 133 [PDC20276]
  Promise FastTrak 133 [PDC20277]

  This driver adds support for the older series of Promise EIDE disk
  interface devices. Each device supports up to 4 disk drives that
  can use UDMA disk access (100MHz for Ultra 100 up to 133MHz for
  Ultra 133).

  If multiple cards are installed you might have problems booting if
  the BIOS versions for the cards are different. Therefore the driver
  attempts to do dynamic tuning of the chipset at boot-time.

  If you say Y here, you need to say Y to "Use DMA by default when
  available" as well.

  If unsure, say N.

Steven,

Thank you for this. I have not migrated to 2.5 yet so Kconfig is a brave new 
world :-)
