One of the kernels has that compiled in, along with drivers. It's a
one-size-fits-all kernel, tested on many machines.
I really doubt if libata alone would do much for me, as the disk and
bios doesn't really want to know about ata at all. We're 1998 here,
remember. ATA has to be disabled for this to read the disk at all.

I did chase for an old 2.4.18 kernel from my last laptop, and that halts
at the same place with a complaint about devices, (Can't open an initial
console) so I'm tarring the 2.4 /dev directory (7.5MB) bzipping it
(86k!!) and sending it over and I'll try that next. I'll probably go
down in flames later in the boot, but we'll see...

Nearly identical IDE messages - all the lines about PIIX4 as before,
then
hda: 6332256 sectors (3242MB) w/128Kib Cache, CHS=6282/16/63, DMA
Partition check:
 hda: [PIBL] [785/128/63] hda1 hda2 hda3 hda4 (That's right - there's
more of them now.)

Well, I got rid of the 'initial console' error. I still get to
EXT3-fs mounted root (ext3 filesystem) readonly
Freeing unused kernel memory: 220k freed
__WE HALT HERE__
No initial console error (it evidently was opened) and then ???
http://www.redhat.com/docs/manuals/linux/RHL-9-Manual/ref-guide/s1-boot-init-shutdown-process.html
end of section 1.2.3

Evidently some failure to launch init.

1998 is well into the world of ATA (IDE is just a confusing othername)

Boot the kernel with initcall_debug=1

and it will spew a list of each initializer as it calls it, you can then
see which is the last called and look it up in the symbol table

Yeah I read it as 'faster ide' but the board/disk won't do it. The disk
seems up to it, but something else is dodgy.

That's the sort of thing a luser like me needs to know! 
/busies himself compiling a _working_ 2.6.22.6 kernel without gigabytes
of network stuff clogging buffers and with symbols in . . . split & load
by floppy, Reassemble.

Much later:
These initcalls all came in, ran for a 0-5 milliseconds, and returned
zero unless otherwise stated. There are more, but they're at the
beginning of the kernel, when it's setting itself up. I can copy the lot
if needed.

The above output seems to indicate that the kernel is still relying on
drivers/ide instead of libata. To change this, I'd suggest setting
"CONFIG_IDE=n" and "CONFIG_ATA=y" in your .config before compiling the
kernel. Also, make sure everything that starts with CONFIG_ATA,
CONFIG_PATA, CONFIG_SATA, and CONFIG_SCSI is set to "y".

OK, managed this at the second attempt.
Checked the .config with grep . I even thought of converting hda to sda
in fstab & grub. First time I failed to compile in ext3, so I got
'couldn't mount root' stuff. This time I'm using the system above the
1024 cylinder limit, so I'd expect that 'couldn't mount root' again if
it couldn't read it. Apparently the 1024 cylinder thing was a red
herring.

We wait at exactly the same place. Typing onscreen works. I'll spare you
all the initcalls, and just mention the relevant ones

Adding init=/bin/bash is no better.

Just to nail the possibility, I also did a chroot into the system I
built (here on an Athlon which is on that laptop) and ran the init
program. I got one very surprised and confused init, but it ran until I
killed it. 

I'm hoping just for a diagnosis - "X is wrong" I gather the ide stuff is
old, but ok

So its the user space which is broken. Make sure the user space has the
right /dev etc - and is for the right CPU - a 200MHz pentium means you
need i386 or i586 binaries. i686/athlon binaries would produce the effect
you report.

Remember this? The problem appears to have been uClibc-0.9.29.

Dropping the system to uClibc-0.9.28.3 and building the minimum as a
proof of concept, I'm running with init=/bin/bash. This is using the
same 2 kernels, one compiled under uClibc-0.9.29, and one under glibc
(not installed there) which seems to indicate that the kernel is fairly
libc independent. I have both systems on that laptop currently.
Hda3(with uClibc-0.9.28.3) boots whereas the same system on hda4
(uClibc-0.9.29)does not.

It's actually quite audible whether it works or not, as you barely hear
the hard disk on the dodgy one at all, while the good one gives it a
thrashing before coming up with. It's either that libc or some i686 code
sneaked through to the old pentium. If I knew a handy way to check that,
I'd do for it.

I agree that the problem is in userspace. I can think of two
diagnoses:

1) The userspace components of the distro you’re using are
mis-configured. To eliminate this possibility, boot the computer from
Debian installation floppies:
 
http://http.us.debian.org/debian/dists/unstable/main/installer-i386/current/images/floppy/

See installation instructions below:
http://www.debian.org/releases/stable/i386/apas02.html.en#howto-getting-images-floppy

At one point during the Debian installation, you’ll be able to press
“Alt-Ctrl-F2” and get a console. From here you can manually mount the
various partitions. If you can mount and read the partitions, then
everything is fine and you can go ahead and install Debian or another
distro. If any step fails, try to capture the output of the ‘dmesg’
command from the console and email it to the list.

2) If mounting fails, your drives might be formatted with a
proprietary Disk Drive Overlay (DDO). You would have to either a)
remove the DDO using the same proprietary software that installed it;
or b) reformat the disk.

I did use a uname hack, so the last kernel tried was compiled for i486

It doesn't find the time source or the PS/2 mouse very easily, so if IDE
relies on that, that could be the issue. The ide messages all come in a
bundle. Ide1 has no devices.

Booting the same kernel on a newer box gives me these differences.

I suspect a 1024 cylinder limit problem. The kernel lies above cylinder
4000 and I have no way of finding out where. But grub finds it, loads
it, and boots it! The only other access is under tomsrtbt, which won't
chroot into the new system. Windows 2000 also boots from a grub boot
floppy, but I have to kill that (and my usb connection with it) to come
in under 1024 cylinders. Bios are the latest revision afaict.

Please cc me on this as I am not a programmer and am not on the list.

Let me give you a laugh on this, and you can tell me if anyone can solve
it quickly or slowly.

I got fed up with this, and dumped windows. I feared that the correct
cylinders value was getting through lba to nobble access above 1024
cylinders. So I repartitioned and got the entire thing below the most
pessimistic 1024 cylinders; It's all below the 504MB limit.

The same thing exactly happens, which would indicate that 1024 cylinder
problem was not the cause. I've also lost usb access, because my shiny
new system won't boot, and windows has been overwritten.

That leaves me curious as hell as to what's going on.
