PCI IDE Adapter for PPC/Linux

[James F Dougherty]

(LOL) .... I have the Promise Ultra-66..... since it's
not working, this is what prompted me to look for an
alternative ..

I have ported MontaVista HHL (Linux 2.4.2) to
a custom processor board, and have been
trying to run fdisk to setup a mountable root
drive.

Kernel is 2.4.2, with the Promise driver compiled in.
I boot up, and it finds the card, and sometimes hdb
is showing up in DMA mode ...

Now, when I run fdisk .... it either cannot find the device (when
compiled kernel with INCLUDE_DEVFS

mousse-(17):[11:31pm]: [/>devfsd /dev
Started device management daemon for /dev
mousse-(18):[11:31pm]: [/>fdisk /dev/hda
modprobe: Can't locate module /dev/hda
modprobe: Can't locate module /dev/hda

Unable to open /dev/hda
mousse-(19):[11:31pm]: [/>fdisk /dev/hdb
modprobe: Can't locate module /dev/hdb
modprobe: Can't locate module /dev/hdb

Unable to open /dev/hdb
mousse-(20):[11:31pm]: [/>

Or, when I run with a standard dev filesystem and the device
files created with scripts/MAKEDEV.ide it gives me an error,
cant find module block-3 blah blah blah...


Any ideas?
