This is a Promise Ultra133 card.
It words perfectly under debian, and problerly also other distros.
Pls note. You are able to install more then just one card to your computer.
This enables you to have +8 harddisk/CD-ROM/DVD drives on your computer.
Just note, that the linux kernel is able to see this devies during startup, but if you have more then 8 devies, they are not automaticly added to /dev/hdX.
So use /dev/MAKEDEVICE /dev/hdX, where X marks the location of your newly added drive.

Then use the normal procedure with fdisk/mkfs/fstab

This controller has worked seamlessly with the above distributions while plugged into a PCI slot on this Asus K7V motherboard. This is with various Western Digital and Maxtor hard disk drives hanging off it.

This is a great controller card. Once I installed the card the system recognized it and there were no drivers that needed installed.

I had a little trouble when I first installed it due to bios settings. The system was a unstable and during file transfers would lock up. Took me back to the windows days. :) After I set the bios for hard drive ata settings, boosting them up the thier max, then the system stabilized and has run great since.

I still give the card a rating of 10 since it was settings on the motherboard that were causing the instability. Once they were set correctly the system and the controller have performed excellent ever since.

Promise Ultra 133 TX2 - Worked without a hitch, right out of the box. Never needed a driver (can't say the same for XP!) Highly recommend! Running with 200GB Maxtor DiamondMax.

i have the promise fasttrak 20270 series, and it work straight away after plugging it onto my ecs p4s5a motherboard.

The device connecting to it is 1x 200gb WD jb and 1x 250gb WD jb series hdd running on span(jbod) mode.

I've tracked this down further now, and have found in google groups, the linux kernel group and the linux ide group, that there is in fact a problem with the driver for the later model Promise controllers.
