Multiple IDE Controllers 10
hornerj asks: "I was just reading the highlights on the 2.4 kernel and I see that Linux currently has support for more than 4 IDE devices. I have always been told that multiple controllers was a thing of the past and that finding a good controller was impossible. Where can I find more information on installing a second IDE controller, for my 5th, 6th, 7th, and 8th devices, and where can I find out which IDE controllers are supported? I haven't seen the HOWTO for multiple IDE controllers yet. Is there one?
Thanks.

FWIW, the BIOS "implementation" is similar to motherboard SCSI. There's that entry that says "boot from A/C/SCSI" except now it's the extra IDEs. Then, when you boot, after the normal drive detection , there is the extra drive just like the "Hit Ctrl-A" SCSI boot.
see the motherboard at http://www.bp6.com/ [bp6.com]

Promise [promise.com] also makes ATA66 controllers, among them IDE RAID (!).
Linux support? No idea...

Uniform IDE Patch && upto 20 IDE devices (Score:2)
It works fine on my newer via chipset motherboard, but doesnt work on my old intel hx chipset. So having multiple ide cards must need some level of bios support.
Support for it and the promise card are via the uniform ide patch.
There is also a patch to support upto 20 or so devices, from what ive read (etiehr the linux kernel or linux-raid mailing list) it isnt a big deal to support more ide devices.
If you look on your local kernel mirror under people/hedrick you will find the uniform ide patch.
I've used up to 3 IDE chains on one machine before (Score:2)
As far as I know Linux supports just about everything out there in the IDE controller world. The Promise PCI UDMA controllers definitely work and have acheived quite a bit of popularity. They cost $20-30 and have 2 controllers on a board. Lots of people are using them to build cheap software RAID solutions.

I have a Promise ultra/66 on my p100
i was using the 2.3 branch of the kernel(i belive that is were ultra/66 support starts)(there is also a patch aval for current kernels(i think), search for ultra66 at redhat to find the patch maintainer).
I was able to use both controllers (the ultra/and integrated hdcont) with no problems -xcept an the kenel being a bit unstable at times.
