Hi,

Sorry if I'm duplicating the issue, but I've searched the list and didn't find 
a similar report. I've just compiled 2.6.20-rc4 and I have trouble booting. 
After some investigation, I find out that my IDE chipset is being discovered 
as SATA, so my hard drive is not /dev/hda, but /dev/sda. When I passed the 
correct root=/dev/sdaX option to the kernel, it booted fine and everything 
seems to be working. But it puzzles me why, this motherboard doesn't even 
have a SATA chipset. Is this abug or a new feature? :) My IDE chipset is:

00:09.0 IDE interface: nVidia Corporation nForce2 IDE (rev a2)

Regards,
DImitar G. Katerinski

It seems you compiled in support for "PATA", more specifically for:

> 00:09.0 IDE interface: nVidia Corporation nForce2 IDE (rev a2)

"<*> AMD/NVidia PATA support (Experimental)"

in the "Serial ATA (prod) and Parallel ATA (experimental) drivers" menu 
under "Device Drivers". PATA is what is also known as IDE and the PATA 
drivers are a new set of IDE drivers, using the same infrastructure as 
SCSI and SATA (and USB, and ..). Yes, they're newly integrated in 
2.6.20. One of the advatages of these new drivers are better error 
handling than the old IDE driver.

I'm using that same specific driver by the way (on amd756) and it's 
working very nicely for me.

Rene.
