Hi Simon,

Forget about these old patches. Go to my PCI page:

http://www.cpu.lu/~mlan/linux/dev/pci.html

and get yourself my latest patches for either 2.2.15 (kernel.org) or
2.3.99-pre7 (linuxcare.au) kernels. For 2.2.15, you need Andre's patches
in addition to mine. Apply his IDE patches first.

To all those interested: there are new patches up for 2.2.15; I screwed
up with the older ones. Went back to an old version of my PCI patches.
Damn ;-)

Great! It's working without a hitch (but with a few kernel args!).

Which ones are those? I need none; I could do with idebus=xx for bus
frequency; but the default is ok...

I use an IMS TwinTurbo card driver that I can't get to work in 2.2.15, so I'm
stuck with 2.2.12. I've had to add some hde=noautotune and
hde=4092,13,63 for an old Seagate ST32122A. None of those was needed
with 2.2.15.

I have to say that I can't put my card in slot 3 or 4, but only in 1 or
2. Not an issue for me but you may want to know ...

What was your machine again? There might be an issue either with bus
mastering (some brain-dead designs don't allow bus masters in all slots;
the Promise is a bus master) or with multiple PCI buses. In the first
case there's nothing you can do; in the second case I might have screwed
up my patches....

It's a Umax J700/180. lspci:

00:0b.0 Host bridge: Apple Computer Inc. Bandit PowerPC host bridge (rev 03)
00:0d.0 Unknown mass storage controller: Promise Technology, Inc.: Unknown device 4d38 (rev 01)
00:0e.0 Display controller: Integrated Micro Solutions Inc. IMS9129 (rev 01)
00:0f.0 PCI bridge: Digital Equipment Corporation DECchip 21052 (rev 01)
00:10.0 Class ff00: Apple Computer Inc. Grand Central I/O (rev 02)

Also, the Promise Card is the only one IDE controller on my Mac, but it
gets detected at ide2 and ide3. Not an isssue for me neither :-)

CONFIG_BLK_DEV_OFFBOARD=y in your .config; the option is 'Boot off-board
chipsets first'. I guess reserving two IDE buses that are not actually
probed is braindamaged PC legacy ;-)

Be carefull when actually activating this, as your disks will change
devices, and your /etc/fstab will be out of sync!

OK. thanks.

I've never had those problems with my Maxtor disk....

Aha. I suppose this bridge goes to bus 2, with slots 3 and 4. Either the
PCI code doesn't (for some unknown reason) support that bus, or it is
not master-capable. Can you send an lspci with some card in slot 3 or 4?
