I have two of the Promise SATAII150 TX4 PCI cards [1] and have managed 
to get them to work with the v2.6.9 kernel [2].  I was able to do this 
by following some of the steps given in the thread [3] posted in a 
message sent about the same card but in chipset/motherboard form [4].  
The following are the parsed results of an 'lspci'.

The following are the parsed results of an 'lspci -vvn'

I had to create a fully patched Fedora Core 3 kernel SRPM in order to 
enable this card.  Following is only the patch to the kernel itself.

I hope that this, at some point, can be included in the full 2.6 kernel 
tree.  I have three ports in use on the 02:0a card while I have two 
ports in use on the 02:0d card.  I've been using them since Friday 
night, 20041119.  This is, of course, only possible thanks to the very 
usable code for the Promise driver provided by Jeff Garzik and/or Red Hat.

Thanks,
Peter Smith
