Their marketing is deceiving and fraudulent. Their software raid is less flexible then Linuxes, and it's performance is inferior. The only advantages of a promise 'raid' controller is cross-OS compatibility and a simplified booting process. Promises Linux 'drivers' are proprietary and a violation of the GPL. Because their drivers are closed source, you can not debug any kernel with it loaded and you will not be compatible with future upgrades to your kernel without promises good will. Because of these reasons, it would be advantageous for Linux to understand promises boot signature and allow Linuxes built in raid driver to be used on promises 'raid' disk. Allowing for the cross-os compatibility and easy booting but retaining the flexible, high performance and open source of the Linux code. Unfortunately, promise is more concerned with living their lie then providing a high quality product to their customers and refuses to provide the tiny bit of needed information. - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
Re: Promise RAID controller howto?
Hi, as far as I can see (you're talking about the "rel.tgz" archive from the LinuxBETA directory, don't you?), this is just glue code for their binary only "ftlib.o" driver. No real open source here. Maybe Andre can work something from the header structures. But then again, the archive is dated 9/28/2000, it's not exactly new...

Re: Promise RAID controller howto?
Hm i have the Promise raid source for 2.2 kernel modules so what do you mean by opensource signatures i have it working for 2.2 kernels but i can't get it to work properly in 2.4 So if someone want to look at the source !!! it can be found on www.promise.com Assie Andre Hedrick schreef: > On Tue, 27 Mar 2001, Henning P.

FreeBSD supports this ATA-RAID. I have got a printout of the sources here. From where did they get the permissions/code/docs... to put it into their kernel? Currently I am working on kernel 2.4 RAID support for HPT370 (also included in FreeBSD). I hope it will work soon. I want to upgrade to debian-woody. regards, Wilfried PS: You are right, these IDE-RAID "controllers" are pain. - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/

Promise RAID controller howto?
Hi, I know, that this is a FAQ and the Promise RAID controller card is not yet usable as a RAID board under Linux 2.x but is there a way to use the controller just like the UltraATA 100 controller? I know, that "input high == UltraATA core, input low = RAID core" according to Andre Hedrick but I really don't care about the RAID core. I want to use this controller to drive JBOD. Can one do this? The disks need not to be interchangeable to other controllers. Just be accessible. 2.2 solutions preferred, 2.4 ok. Regards Henning -- Dipl.-Inf. (Univ.) Henning P.
