PCI RAID controller

I have recently purchased a cheap ATA RAID controller its a PROMISE 66mhz RAID controller, and i was wondering what drivers i need compiled in the kernel to be able to access my hd, also any links reads are appreciated.

Also is a 66mhz raid card too slow ??

Thank you

ATA Raid support is available in the stock kernels 2.4 and 2.6, you just need to pick the right option in the kernel config.

66 mhz is not the fastest available at the moment, but wether is it to slow is dependent on what you intend to do with it. I have a webserver/firewall running on ata33 and is plenty fast enough for that.

This link has some basic info on the subject, but you could also check the docs at www.linux.org as they have some very good docs on the matter.

good luck

what do you mean 66mhz is not fast enough?

it is the fastest you can get atm..

unless you mean UDMA66 :?:

anyway, I doubt most harddrives really get over 66mb/sec, so you should be right

no kernel really has support for the fasttrack side of things - except a few 2.4 kernels - ck-sources comes to mind.

but if you want to use it as a standard ide controller and use linux software raid, then any kernel will support it, just include promise ide support (and make sure your chipset is listed - like PDC20215.

I suppose just a normal pci controller card + software raid would be the cheapest way and probably even the best method. Hardware raid isn't exactly that great, many times the chipset is quite buggy.
