ide-core.o & libata.o ICH5

  Can anbody tell me the correct insmod sequence for the initrd disk to
get my drives up and running on an intel ICH5 chip in native mode?

I am running an ASUS P4P800 SE MB. It has two SATA ports with maxtor
6Y160M0 160GB hard drives. It also has two parallel ATA ports. One with
a dvdwriter and a fried 140 GB maxtor disk from my crashed 486 server
machine.

I want to boot off of my SATA disks and move the recoverable parts of
the fried disk  to another backup hard drive on the other (primary)
parallel ide channel.

I am currently running the bios setting in compatability mode with the
two sata disk configured as the primary channel, and have downloaded
various 2.4 versions of kernels and various patch kits to no avail.

Right now I can boot kernel 2.4.27 with the bios in compatability mode
and all of the ide stuff compiled into the kernel. When I switch the
bios to native mode and compile in the kernel with scsi support, libata
and piix the kernel crashes with with a stack dump that locks up the
screen so I can't scroll back to see what happened. I suspect that it
might have something to do with the bad "hdc" disk Maxtor 4R120L4 that
gives me "hdc: dma_intr: error=0x84 {DriveStatusError BadCRC)" and "hdc:
dma_intr: status=0x51 {DriveReady SeekComplete Error }" when in
compatability mode. This is a "SMART" drive where the bios tells me to
back it up and remove it.... which I am attempting to do.

I tried to compile just the scsi stuff and leave ide-everything out of
the kernel completely... that didn't work. Stack Dump. No hard copy
saved. Don't know how.. and to lazy to insmod carbon-record.o.

So then I tried to compile everything as modules with both ide and
libata together, hoping that I could configure two different "initrd
disks"... one for compatibility mode that I know is working for backup
and migration purposes, and the other with libata to test the native
mode.... No luck there either. The system locks, or can't mount
root=/dev/hda3.

Except for the last two months I haven't compiled a kernel in three of
four years or more. I am upgrading my server from 100MHz 486 w/ 200+gigs
 to a 300MHz pII, and my worstation from a pII/100MHz to a pentium-4
3.2GHz 1GB ram. All my machines were running RedHat 6.1.92 kernel
2.2.15. I am running RedHat 8.0 on this machine (pentium 4) with the 2.4
kernel set. Currently kernel-2.4.27 with patch 2.4.27-rc3-libata1.patch.

The first problem is that nomatter what... the RedHat mkinitrd always
does the "Right Thing" and includes ide.o into the initrd disk. I
suspect this is what causes me the system hangs when I switch over to
native mode in the bios. The last message I get is "hda: attached
ide-disk driver." and then "hda: host protected area =>1" and nothing
else...

The other confusing thing is that the kernel always seems to say
attaching ide-disk....( or maybe it was ide-scsi ) even when the
ide-disk.o is not included in the linuxrc scripts... but it may have
been included in the /lib directory.

Another confusing thing is where to put the kernel parameters, or how to
find out what parameters the different modules accept. I tried.
insmod ide-core.o idebus=66 hdd=ide-scsi
insmod ide-disk.o idebus=66 hdd=ide-scsi
insmod piix.o idebus=66 hdd=ide-scsi
insmod ide-detect idebus=66 hdd=ide-scsi
Not one module accepts the parameters, the commands are already kernel
boot parameters, and the ide-bus always configures at 33Mhz.?????
This gives me a message that ide0 is already in use, hda and hdb never
get probed and the boot dies cause it can't find the "init" program on
root=/.

I tried to make an initrd recovery disk that had copies of /bin /sbin
/etc and /lib that would give me a bash prompt... but that didn't work
for me either. It still says that it either can't mount root=/dev/ram or
INIT is not found.... Now that I think about it... the RedHat 8.0
mkinitrd puts everything into /bin and creates a symlink that points
/sbin to there. I'll try putting /sbin/init where it belongs and try
that. The idea here is that if I can get a prompt on tty1 after the
kernel boots using a ram disk then I can try probing the modules in
different orders until I find the sequence that works correctly.

I would be happy to help out with testing the libata stuff, if I could
only just get it to boot up.
