define "near future"? PROMISE tech (prolly the worlds best IDE/ATAPI controler maker says)

"A driver for linux (RedHat distribution) will be available in the future"

and thats all they say. no idea about ABIT, but linux isnt mentioned anywhere on their pages.

it work right now.... but you have to patch your kernel to support ata66...
i m running redhat 6.1 with a promise 66 ide controler..

if you dont want to patch your kernel (or don t known)
you will have to wait for a linux distribution who will have kernel 2.4

Good news for ya ! look what i found

This is essentially the same as the
Ultra33 with support for the new UDMA mode 4 66 MB/sec transfer speed. Unfortunately it is not yet supported by 2.2.x kernels.

There is a patch for 2.0.x and 2.2.x kernels availabe at http://www.kernel.org/pub/linux/kernel/people/hedrick, and support is included in the 2.3.x development kernel series at least as of 2.3.3.

what you have to do is plug your hd on you ata33 (motherboard connectors)
install linux-patch linux for ata66-plug something on the promise66-check if the linux can mount the device that is on the promise 66.
if it s work remove the hd from the ata33 to the ata66.
and it should work
