max number of ide controllers?

max number of ide controllers?

[Charles Wilkins]

[-- Attachment #1: Type: text/plain, Size: 447 bytes --]

I have been running with the 2 onboard VIA ide hd controllers (ide 0 and ide 1) along with a creative labs ide contoller on a SB32 soundcard (ide 3). This has had the cdrom and zip drive.

I just added a Promise Ultra100 and it has assumed the role of ide 3 and ide 4. The onboard controllers are still ide 0 and ide 1, but the creative labs controller isnt coming up.

Is there a max number of ide controllers that linux-2.2.18 can support?

Maybe set the new dual controller to be IDE 2,3 and have the SB32 as IDE4.
Also, you can check /proc/ioports and /proc/interrupts to see if there
actually are conflicts with the port ranges or interrupts of your card.
I'm guessing not, because it worked before, but you never know.

IDE cards actually have 2 port ranges, so it may be that with the new card
you are getting conflicts.  My system shows:

0170-0177 : ide1
01e8-01ef : ide2
01f0-01f7 : ide0

0376-0376 : ide1
03ee-03ee : ide2
03f6-03f6 : ide0

The second ide2 port is in the same place as ttyS2 (com3)...

Cheers, Andreas

The correction has been made. Thank you.

This is good to know.

I also corrected my previous posting regarding which ide controller was
which.

without the promise card.
onboard primary is ide0
onboard secondary is ide1
SB32 is ide 2

with the promise card
onboard primary is ide0
onboard secondary is ide1
promise primary is ide2
promise secondary is ide3
SB32 does not come up

I added this to lilo.conf:
append="ide2=0x168,10" and ran lilo

This is what I got:
ide_setup: ide2=0x168,10
.
.
ide2: ports already in use, skipping probe

The promise controllers then setup as ide3 and ide4, but the SB32 still does
not report.
Any ideas?

I also tried others such as 0x1e8,10 and 0x180,10 and they did the same
thing.

I am running kernel 2.2.18 with ide.2.2.18.1209.patch as well as the latest
