Have you tried using the special kernel that I compiled for this 
controller?   I also posted modules for the same 2.4.31 kernel.

v - via
p - promise
s - sis

The kernel has drivers for these three common fast IDE controllers.

If you connect the hard disk to the add-in controller it is no longer hda, 
it is probably hde (or f, g or h).  You will need to make the devices with 
mknod - hde, hde1 2 ... 8.

BL does not even come with extended partitions for anything but a.
(I see hda1 through 9 in BL2, but had to make my own hdb5 and hdb6).

I forget what happens if you disable the onboard controller (other than 
the CD-ROM drive is said not to work with the add-in controller).  It may 
change the drive letters so the primary master on the card is hda again.

I think even with the correct drive designation I needed the driver in the
kernel in order to boot linux from that partition, otherwise it would not 
find the drive.  (The onboard VIA and SIS controllers worked without the 
special drivers, but at about 1/10 expected speed.  I think one or maybe 
both of these would work only compiled into the kernel, unlike the nforce 
which could be added as a module but was not very fast).

I think I flashed the BIOS on this card, I forget why.  Read my postings.

I am not an expert but I hope this helps.  I spent days searching the 
internet for the answer.
